We were asked a few times about trying out Liberapay. It is different from other recurring funding platforms (such as Patreon and Tipeee) that it is managed by a non-profit and have lesser fees (from what I understand, there are payment processing fees, but they don’t add their own fees) since they fund themselves on their own platform (also the website itself is Free Software).
Though we liked the concept, until now we were a bit reluctant for a single reason: ZeMarmot is already on 2 platforms (we started before even knowing Liberapay), and more platforms mean more time spent to manage them all, time we prefer using to hack Free Software and draw/animate Libre Animation.
Nevertheless recently Patreon made fee policy changes which seem to anger the web (just search for it on your favorite web search engine, there are dozens of articles on the topic) and as most Patreon projects, we lost many patrons (at time of writing, 20 patrons for $80.63 of pledge left in 4 days, more than 10% the patronage received from this platform!).
So we decided to give Liberapay a try. If you like ZeMarmot project, and our contributions to GIMP, then feel free to fund us at:
both EUR (€) and USD ($) donations are accepted, which is cool;
there are no news system so one has to get them oneself (for instance reading the project blog or twitter);
all patrons are fully anonymous (which means they won’t appear in credits of the movie);
localization is supported (right now our page is only in English, but we will make a French version soon!).
Now this is just another platform, we are not abandoning Patreon and Tipeee. Don’t feel like you have to move your patronage to Liberapay if you don’t want to. From now on, this will just be one more option.
Finally we remind that ZeMarmot project is fully managed by a non-profit registered in France, LILA. This means there are also other means to support the project, for instance with direct bank transfers (most European banks allow monthly bank transfers without any fees, so if you are in the EU, this may be the best solution), or Paypal (though for very small amounts, fees are quite expensive, they are quite ok for most donations), etc. To see the full list of ways to fund LILA, hence ZeMarmot and GIMP: https://libreart.info/en/donate
Too long, didn’t read? In a few words: our GIMP development + ZeMarmot production is currently funded barely above 400 € per month, this doesn’t pay the bills, my main computer broke today and Aryeom’s graphics tablet has been working badly for some time now. We are a bit bummed out.
So we call for your help!
You can fund GIMP development and ZeMarmot production on Patreon or Tipeee! Read below for more.
If you read us regularly, you know that I am hacking GIMP a lot. We are just a handful of regular developers in GIMP, I am one of them. My contributions go from regular bug fixes to bigger features, maintenance of several pieces of code as well as regular code review from contributed patches. I do this in the context of ZeMarmot project, with Aryeom Han, director and animator. We draw on and hack GIMP because we believe in Free Software.
On the side, I also contribute to a lot of other Free Software.
Our absolutely-not-hidden goal is to be able, one day, to live from hacking Free Software and creating Libre Art. But clearly there is no denying that we are currently failing. With about 400€ a month for 2 people, association LILA can barely pay a few days a month (by the rules, which means a good part of the sum even goes to non-wage labour costs). These 400€ are not even the monthly rent we pay for our 1-room flat (31 m², in the far suburb of Paris); so you would assume well that we don’t live from it. We mostly live off savings and other things to pay the bills. These “other things” also use time we would rather spend on drawing and coding.
We would indeed enjoy working full-time on ZeMarmot, creating Free Software and Libre Art for everyone to enjoy. But we are very far from this point.
The main reason why we have not stopped the project already is that we promised we’d release the pilot. Funders are counting on us. Of course the other reason is that we still hope things will work out and that we will be able to live from what we love. Still the project is done at slow pace because we can’t afford to starve, right? So we are at times demoralized.
This is why I am doing this call. If you can afford it and believe that improving GIMP is important, then I would propose to fund ZeMarmot which supports paid development.
Similarly if you want to see more Libre Art, and in particular cool animation films, and maybe later other movies under Libre licenses in professional quality, then I again propose to support ZeMarmot.
And so why is this post released today? The situation has been hard for months now, but today it is dire: my laptop just broke. It just won’t turn on. All my data are safe since I do regular backups (and I think the hard drive is still ok anyway), but I don’t have a computer anymore to work on (I am writing this on a 8-year old 32-bit netbook which barely stands opening a few browser tabs!).
On her side, Aryeom’s graphics tablet has had issues for months. As you may remember, we partly dealt with them, but the tablet regularly shuts down for no reason, we have to remove and put back the battery or similar annoying “workarounds”. And we fear that we have to buy a new one soon.
So that’s what triggered this blog post because I realize how precarious is our situation. We barely get funding for living bills, we eat our savings and now we have (expensive) material issues. So we are calling you all who like Free Software and Libre Art. Do you believe ZeMarmot is a good thing? Do you believe our project has any meaning and that it should continue for years and years? We believe this, and have believed it for the last 2 years where we have been trying. If you do too, maybe help us a bit, relatively to your means. If you really can’t afford it, at least you can spread the word.
ZeMarmot is a wonderful experience for us, and we really don’t want it to have a bitter end (though we won’t regret a second of it).
Note: this is a copy of a post initially posted on Patreon and Tipeee.
Last month, we released the third development version of GIMP, version 2.9.6, as preparation of the next stable version, GIMP 2.10.
Same as for previous versions, ZeMarmot project was one of the major contributors with 274 commits (out of 1885 total for this release) by Jehan, 4 by Aryeom (some icons, a new paint dynamics “Pressure Size” very useful for flat coloring, and the splash image for this development version), and even for the first time, 3 commits by Lionel, a board member of LILA association. Hence about 15% of GIMP 2.9.6 was brought to you by ZeMarmot! 🙂
To get some more insight, you can have a look at the official announcement. And if you want to get the full and accurate list of Jehan’s contributions in particular, it is available on the source repository.
Brought to you in 2.9.6 by ZeMarmot
made libgimp as thread-safe, which basically means simplify plug-in developer work to have plug-ins using several cores (now all desktop computers are multi-core);
display angles when drawing lines;
code review for WebP image support, as well as some improvements and fixes (and even a patch upstream on libwebp library);
capability to switch exclusive visibility of layers inside layer groups only with shift-click (feature requested and tested/used by Aryeom for a few months before adding it to GIMP);
contributing to the Darktable and RawTherapee developers efforts for our new “raw” plug-in allowing importing RAW files through these third-party software and into GIMP (GIMP project advocates for cooperation with other Free Software);
contribution to allow GIMP to follow GEGL multi-thread limit (once again to have a better usage of modern computer processors but now in GIMP core in particular);
various improvements of PDF support, in particular multi-page PDF export from layers (this is the part where Lionel from LILA made his first steps as a developer with Jehan’s help!);
code review and fixes for improved support of PCX images import and export;
capacity of plug-ins to be installed in their own subdirectory, which should in the long run allow to get rid of the “DLL hell”, in particular on Windows system, a very common issue where some plug-ins embed libraries breaking other plug-ins;
change various defaults values to get to up-to-date standards (bigger default font size, fullHD as the new default image dimension, 300 PPI default resolution instead of 72…);
intelligent adaptation of physical dimension precision based on printing resolution to allow better precision in various parts of the software (measure tool, status bar, etc.);
capacity to choose the icon size, allowing to adapt GIMP on smaller or bigger screen and in particular high density screens, etc.;
auto-detection of native resolution of your screen to choose better default icon size (this default choice can still be changed, cf. previous point; but at least you should get better defaults);
vector icons by default for the various size support;
welcome new code contributors by adding a vim coding style file and integrating contributed emacs and kate coding style files;
Flatpak package for GIMP;
and much more! Bug fixes and minor features by the dozens!
Flatpak for creators on Linux?
For the creators who use GIMP on a GNU/Linux operating system, you may have heard of Flatpak, the generic application package system. Since we also exclusively use Linux, it felt important that GIMP be available in a timely manner (with distribution package systems, it is not unheard of to have to wait months after actual release to get some new version!). We take the opportunity of the release of 2.9.6 to test a first public Flatpak package. Since we don’t have a stable server, we made it available to our Patreon and Tipeee contributors only for the time being, then will try and make it available for everyone very soon!
For information, Windows already has a GIMP 2.9.6 installer available; and a MacOS package should hopefully soon get uploaded (it will depends on this package maintainer who has some family priorities right now). These are not maintained by us. » See the download page! « 🙂
Thanks and “en route to GIMP 2.10”!
I hope you appreciate our contributions to GIMP! Know that these are all thanks to our contributors, be them Patreon or Tipeee, in previous crowdfundings or the ones who make direct donations.
It is not easy everyday because we seriously lack funding, and we have had some blues more than once. ;-(
Yet the many of you who never failed us and continue to support us give us some courage.
Thanks to you!
We will continue in order to bring you an awesome stable GIMP 2.10. 🙂
This is the second video to present GIMP Motion, our plug-in to create animations of professional quality in GIMP. As previously written, the code is pretty much work-in-progress, has its share of bugs and issues, and I am regularly reviewing some of the concepts as we experiment them on ZeMarmot. You are still welcome to play with the code, available on GIMP official source code repository under the same Free Software license (GPL v3 and over). Hopefully it will be at some point, not too far away, released with GIMP itself when I will deem it stable and good enough. The more funding (see in the end of the article for our crowdfunding links) we get, the faster it will happen.
Whereas the previous video was introducing “simple animations”, which are mostly animations where each layer is used as a different finale frame, this second video shows you how the plug-in handles animations where every frame can be composited from any number of layers. For instance a single layer for the background used throughout the whole animation, and separate layers for a character, other layers for a second character, and layers for other effects or objects (for instance the snow tracks in the example in the end of the video).
It also shows how we can “play” with the camera, for instance with a full cut larger than the scene where you “pan” while following the characters. In the end, we should be able to animate any effect (GEGL operations) as well. This could be to blur the background or foreground, adding light effects (lens flares for instance), or just artistic effects, even motion graphics…
All this is still very much work-in-progress.
One of the most difficult part is to find how to get the smoother experience. Rendering dozens of frames, each of these composited from several high resolution images and complex mathematical effects, takes time; yet one does not want to freeze the GUI, and the animation preview needs to be as smooth as possible as well. These are topics I worked on and experimented a lot too because these are some of the most painful aspect of working with Blender where we constantly had to render pieces of animation to see the real thing (the preview is terribly slow and we never found the right settings even with a good graphics card, 32GB of memory, a good processor, and SSD hard drives).
One of the results of my work in GIMP core should be to make libgimp finally thread-safe (my patch is still holding for review, yet it works very well for us already as you can see if you check out our branch). So it should be a very good step for all plug-ins, not only for animation only.
This allowed me to work more easily with multi-threading in my plug-in and I am pretty happy of the result so far (though I still plan a lot more work).
Another big workfield is to have a GUI as easy to use, yet powerful, as possible. We have so many issues with other software where the powerful options are just so complicated to use that we end up using them badly. That’s obviously a very difficult part (which is why it is so bad in so many software; I was not saying that’s because they are badly done: the solution is just never as easy as one can think of at first) and hopefully we will get something not too bad in the end. Aryeom is constantly reminding me and complaining of the bugs and GUI or experience issues in my software, so I have no other choices than do my best. 😉
You’ll note also that we work on very short animations. We actually only draw a single cut at a time in a given XCF file. From GIMP Motion, we will then export images and will work on cut/scene transitions and other forms of compositing in another software (usually Blender VSE, but we hear a lot more good of Kdenlive lately, so we may give it a shot again; actually these 2 introduction videos were made in Kdenlive as a test). Since 2 cuts are a totally different viewpoint (per definition), there is not much interest on drawing them in the same file anyway. The other reasons is that GIMP is not made to work with thousands of high-definition layers. Even though GEGL allows GIMP to work on images bigger than memory size in theory, this may not be the best idea in practice, in particular if you want fast renders (some people tried and were not too happy, so I tested for debugging sake: that’s definitely not day-to-day workable). As long as GIMP core is made to work on images, it could be argued that it is acceptable. Maybe if animations were to make it to core one day, we could start thinking about how to be smarter on memory usage.
On the other hand, cuts are usually just a few seconds long which makes a single cut data pretty reasonable in memory. Also note that working and drawing animation films one cut at a time is a pretty standard workflow and makes complete sense (this is of course a whole different deal with live-action or 3D animation; I am really discussing the pure drawn animation style here), so this is actually not that huge of a deal for the time being.
To conclude, maybe you are wondering a bit about the term “cel animation”. Someday I guess I should explain more what was cel animation, also often called simply “traditional animation” and how our workflow is inspired by it. For now, just check Wikipedia, and you’ll see already how animation cels really fit well the concept of “layers” in GIMP. 🙂
Have a fun viewing!
Reminder: my Free Software coding can be supported in
USD on Patreon or in EUR on Tipeee. The more we get
funding, the faster we will be able to have animation
capabilities in GIMP, along with a lot of other nice
features I work on in the same time. :-)
Mid-July, we finally published publicly the code of GIMP Motion, our software for animations in GIMP. It is available on GIMP official source code repository under the same Free Software license (GPL v3 and over).
We don’t have a public GIMP release containing this plugin yet. Hopefully it should happen soon, but the code is still much too experimental and incomplete. We are using it daily internally and you are welcome to do so as well, but the released version will be much better. 🙂
So it means that for the time being, if you want to play with it, you will have to build it yourself from source, or wait for someone to make a build (we may provide one at some point).
The video above describes some of the base features for simple animations, such as storyboards/animatics and most common needs for animated images (GIF, Webp…). What we call “simple animations” is when you mostly have several images which you want to succeed at one another. No complex composition with background and character layers for instance. New features will still happen, for instance for panning/tilting/zooming on bigger panels (very common on storyboards as well), and adding various effects (a keyframed blur for instance would be a common movie effect).
We will soon publish a second part video where we will describe the more advanced features for complex animation (the ones with layered background/foreground/characters). Because we just scratched the surface of what we will be able to do with this plugin. 🙂
In an animation film, obviously the design does not refer only to characters. There can be props design when applicable, and of course background design. As an example, the most interesting case is how we designed ZeMarmot’s home! At least the outside part of its burrow, since we never see the inside (unlike in the initial comics attempt).
And obviously on the bottom of this tree, there was a marmot burrow hole.
We thought that was just too cool. Most burrow holes are just in the middle of the landmass, but this felt like a “special hole”. Our main character is not a special marmot, it’s not a hollywood leader, chief of the marmot clan or anything, but still… it’s our hero, right? It’s not just any marmot, its ZeMarmot! So we wanted to give him a special burrow. Therefore ZeMarmot now lives under a cool tree. Only difference is that we didn’t set it on a hill but in a plain, since plains are also very common setups for marmots in the alps.
Here is how the burrow entrance looks in our storyboard:
Then with clean lines:
Finally adding some colors:
Note that this last image is still work-in-progress. Aryeom said she is not fully happy with it yet. I thought it was still nice to show you the progression from our research photos to storyboard sketchs, drawing and coloring, with all the thinking we made on why and what.
Hope you enjoyed this little insight in our work! 🙂
While production on the animation is still going full-steam, we thought we could show what exactly this is about. How do you go from static images to animated ones? Well this is all like progress layers, one step after another.
The Storyboard, then the Animatics
We have already talked about these at length so we won’t do it again. Feel free to check out our previous blog posts on the topic. These are the first 2 layers: comics-like static images (storyboard), and static images displayed in video (animatics).
In the digital world, “keyframes” is used with different meaning. On video formats, it is usually used to distinguish a standalone image in the stream with partial images which cannot be displayed by themselves. On 3D or vector animation software nowadays, it is usually used as extreme points in smooth transition which are computed by algorithm (interpolation). This is more or less the definition given by Wikipedia: “A key frame in animation and filmmaking is a drawing that defines the starting and ending points of any smooth transition.”
This definition is a little too “mechanic” and tied to modern way of animating with vector or 3D (actually it is not entirely true even in 3D and vector but this is what one might think when discovering interpolation magic). Key frames are actually simply “important images” as determined by the animator in a purely judgemental way. Keyframing is part of the art of the animator, more than a science. It is true that they are often starting/ending points of movements, but this is not a necessity. Also called sometimes “key poses”, these are what the animator feels make the movement good or not, in one’s guts as an artist.
Pose to Pose vs Straight Ahead animation
When animating, there are 2 main techniques. The first method is to decompose the movement in key poses (keyframes) as a first step. Then later, when it looks good, you complete with intermediate frames (inbetweens). This is the pose to pose method and demonstrated a bit in the above video.
When you are a big studio, keyframes would usually be drawn by the main animators, and the inbetweens would be left to the assistants (less experienced animators). This allows to share the work with more multitasking. In ZeMarmot‘s case unfortunately, Aryeom does everything, since we don’t have the funds to hire more artists as of yet.
The other method is called “Straight Ahead” and consists on doing all frames one after another without prior decomposition. Timing is much harder to plan with such a technique and you may end wasting more drawing. On the other hand, some animators prefer the freedom it gives and by making movements less perfect, you can also avoid them being too mechanical (in other words, perfect movement are not always what you are looking for when you want to represent living being in their whole perfect imperfection).
Observing Aryeom, she uses both methods, depending on the cuts, as is the case for many animators.
Hopefully you appreciate this insight on the work behind animating life, and this small video where we display the same pieces of a scene at different steps in the work-in-progress, first one after another, then side by side.
You will notice that we mostly show always pieces of the same scene since we really want to try and avoid any spoiler as much as possible. 🙂
This is spring, time of cherry blossoms and warmer weather (well for people in north hemiphere only!). So Aryeom drew a new header image for our blog (as usual drawn in GIMP under Creative Commons by-sa).
How are going your last days of 2016 so far? It’s been a strange year? Well let’s not diverge, and focus on ZeMarmot, then, shall we? First be aware that our dear Director, Aryeom Han, is getting a lot better. She was also really happy to get a few “get well” messages and say thanks. Her hand is still aching sometimes, in particular on straining or long activities, but on the whole, she says she can draw fine now.
Reminding the project
I will discuss below what was done in the last months, but first — because it is customary to do so at end of year — I remind that ZeMarmot is a project relying on the funding by willing individuals and companies, with 2 sides: art and software.
I am a GIMP developer, the second biggest contributor in term of number of commits in the last 4 years and I also develop a plugin for digital 2D animation with GIMP, which Aryeom is using on ZeMarmot. I want to get my plugin to a releasable state by GIMP 2.10.
Aryeom is using the software to fully animate, draw and paint a movie, based on an original story which I wrote a few years ago, about a marmot who travels the world for reasons you will know when the film will be released. 🙂 Oh and the movie will be Creative Commons by-SA of course!
Up to now, our initial crowdfunding (~ 14 000 €) has allowed to pay several months of salary to Aryeom. I have chosen to not earn anything for the time being (not because I don’t like being paid but because we cannot afford it with current funding). Some of it is remaining but is kept to pay the musicians.
Now we are mostly relying on the monthly crowdfunding through the Patreon (USD funding) and Tipeee (EUR funding) platforms. But all combined, that’s about 180 € a month, which amounts to barely more than a day of salary (and with non-wage labour costs, that’s not all of it for Aryeom). 1 day per month to make a movie, that’s far from enough, right?
My dream? I wish we could some day consider ourselves a real studio, with many paid artists, producing cool Libre Art movies going to the cinema (yes in my crazy dream, Creative Commons by-sa films are on the big screen!), and developers paid to improve Free Software so that our media-making ecosystem gets even better and for everybody to use!
But right now, that’s no more than an experiment mostly done voluntarily.
Do you like my dream? Do you want to help us make it real? You can by helping the project financially! It can be the symbolic coin as the bigger donation, any push is actually helping us to make things happen!
Not sure yet? Feel free to read more below and to pitch in at any time later on!
Note that not only the money but also the number of supporters is of great help since it shows supports to bigger funders; and for us that’s good for morale too! A good monthly crowdfunding can also help us find producers without having to abandon any of the social and idealistic aspects of the project (note that we have already been contacted by a production who were interested by the film after the crowdfunding but we refuse to compromise too much on the ideal).
We illustrated Aryeom’s work by 2 videos presenting extracts of her work-in-progress. In this first video, she shows different steps in animating a few cuts of the main character:
In this second video, we examine some cuts of another character, the Golden Eagle, main predator of the marmot:
There are a lot which can be said on these few minutes shown about the work of “animator”. Many pages of books on the art of animating life could be filled from such examples! We will probably detail these steps in longer blog posts but I will still explain the basics here.
Animating = giving life
Aryeom says it in the first video and you can see it in several examples in both videos. When your character moves from A to B, you are not just “moving” it. You have to give the impression that the character is acting on oneself, that it is alive, inhabited, in other words: animated.
This is no surprise one of the most famous book on animation is called “The illusion of life” (by Frank Thomas and Ollie Johnston), also the bedside book of Aryeom. Going this way has a lot of ramifications on the animator job.
Believable, not realistic
Before we continue, I have to make sure I am understood. Even though realistic animation is also a thing (Disney comes to mind), making a good animation is otherwise not necessarily about making it “realistic”, but instead about making it “believable”.
It is very common to exaggerate some movements for various reasons (often because it is funnier, but also sometimes because exaggerating it may sometimes look even more believable than the realistic version!), or the opposite (bypassing anatomically-correct movements). There are no bad reasons, only choices to achieve what you want.
Now that this thing is clear, let’s continue.
You can’t just “move an arm”
The very classical example beginners will be given is often: “lift your right arm up”. That’s it? Did you only move your arm and the rest of the body stayed unchanged? Of course not. To stay in balance, your body shifted to the left as a counterweight; the right shoulder lifted whereas the left shoulder lowered; and so on.
A lot of things will change in your body with this simple action. Even your feet and legs may move to compensate the shift of the center of gravity. As a consequence, you don’t “move your arm”, you “move your whole body” (in a configuration where your arm is up).
This is one of the first reason why to just move a single part in a body, you cannot reuse previous drawings and change just this part. No, you will properly redraw the whole body because if you are to fake life, you may as well do it well.
Note: when you say “animation” to computer people, their brain usually immediately wires to “interpolation“, which is the mathematics to compute (among other things) intermediate positions. Because of what I said above, in reality, this mathematical technique is barely used in traditional (even when digital) animation. It is used a lot more in vector and 3D animation, but its role should definitely be minimized compared to the animator work even on these fields. In vector/3D, I would say that interpolation only replaced the inbetweener role (some kind of “assistant” who draw non-keyframe images) from the traditional animation world.
Timing, silence and acceleration
You often hear it from actors, poets, writers, singers, anyone who gives some kind of life: the silence is as important as the noise for their art. Well I would also add the acceleration and the symmetrical deceleration.
You can see this well on this first example of the video 1 (at 0’41). Aryeom was unhappy with her running marmot which was nearly of linear speed. Marmot arrived too fast on the flower. Well he slowed down, but barely. Her finale version, Marmot would arrive much faster with a much more visible slowdown, making the movement more “believable” (we get to the bases!).
The eagle flight in video 2 (at 1’09) is another good example of a difficult timing as Aryeom went through 2 stages before finding the right movements. With the wrong timing, her flying eagle feels heavy, like it has difficulty to lift itself into the air (what she called her “sick” eagle in the video); then she got the opposite with an eagle she felt more sparrow-like, too light and easy-lifted. She was quite happy with the last version (obtained after 8 attempts) though, and in particular of this very last bit in the cut, when the eagle gets in glider mode. Can you spot it? This is the kind of difference which just lasts for a few hundredth of seconds, barely noticed, yet on which an animator can spend a significant amount of time.
Living still images (aka “line boil”)
A common and interesting effects you find in a lot of animation is about a shaking still image. You can see it in the second video (at 0’33), first cut presenting the proud eagle still on his mountain. Sometimes you want to show a non-moving situation, but just sticking to a still image feels too weird because in real life, there is no perfect stillness. Even if you make all efforts to stay still for a few seconds, you will imperceptibly move, right? So how do you reproduce this? The attempt to stay perfectly still while this being impossible? Well commonly animators will just redraw the same image several times because as much as you can’t stay still, you can’t draw perfectly identical images twice either (you can get very close by trying hard though) and you loop them.
You usually don’t do this for everything. Typically, elements of the background, you accept them to be still much more easily. But this is common for your living character or sometimes to pull main elements which you want to tick out of the background.
Now, loops are very usual in animation. But the higher quality you aim for, the less you have loops. Same as stillness does not exist in life, you never repeat exactly the same movement twice. So even though loops seems to be the first thing many animators will teach (the famous “walking cycles”), you don’t actually use these in your most beautiful animations. When your main character walks, you will likely re-animate every step.
Of course, it is up to you to decide where to stops. Maybe for this flock of birds in the background, far away, just looping (and even copy-pasting the birds to multiply them!) may be enough. Though this is all a matter of taste, time, and money ready to spent on animator-time obviously.
This part has not really started yet, even though it has already been planned (from the storyboard step). But since Aryeom started (first video at 1’06), let’s give some more infos.
Panning and tilting
In animation, where the movement is by essence 2D as well, these refers to respectively a horizontal and vertical camera movement. Why do I need to say “in 2D animation”? Because in more traditional cinema, these will rather correspond to a tracking shot done on rails, whereas panning and tilting refer to angle movements of a static camera. Different definitions for different references. Note that even though 3D animation could be using one or the others, they mostly kept the animation vocabulary.
This gives you a good hint on how characters and background are separately managed. If you have a character walking, you will usually create a single image of the background, much bigger than the screen size, and your camera will move on it, along with the character layers. With fully digital animation, this usually means working on image files of much higher sizes than the expected display size; in traditional physically-drawn animations, it means using very large papers (or often even sticking papers together). As an example, at a Ghibli exhibition, they would display the background for a flying cut of “Kiki’s delivery service” and it would take a full wall in a very large room.
Animation is a lot of drawing
I will conclude the section on animation by saying: that’s a bloody lot of drawing!
As you can see, Aryeom spends time redrawing the same cuts so many times to get the perfect movement that sometimes she becomes crazy and thinks that she is just drawing the wrong animal. The story about the pigeon is a true story and I am the one who told her to add it to the video because that was so funny. Some day, she comes to me and show me her cut she has been working on for days. Then she asks me: “doesn’t it look like a pigeon?”
Hadn’t I stopped her, she was ready to start over.
This is an art where you even draw again when you want to show stillness, and you forbid yourself from using too much shortcuts like using loops. So what do you want: you probably have to be a little crazy from the start, no? 😉
There are actually several “schools”, and some of them would go for simplicity, shortcut and reusage. Japan is well known for the studio Ghibli which goes the hard way as we do, but this is quite a contradiction in the country industry. The whole rest of Japan’s animation industry is based on animating as little as possible. Haven’t they proved so many times that it is possible to show a single still image for 30 seconds, add sounds and voices, then call it an animation?
Sometimes it is just a choice or a focus. Some animation films focus on design rather than believable movements, or scenario rather than wonderful images. For instance, I don’t think you can say that The Simpsons has a wonderful graphics appeal and realistic animation (they even regularly makes meta-jokes inside episodes about the quality of their animation!), but they have the most fantastic scripts, and that’s what makes their success.
So in the end, there is no right choice. Every one should just go the way they wish for a given project.
And this is the way we are going for ZeMarmot!
Just a very short note on music. We have started working with the musicians, remotely and on a physical meeting on December 1st. We have a few extracts of “first ideas” but they won’t do justice to the quality of the work.
I think this will have to wait for much later.
I went so long about animation that I hope I have not lost half of the readers already! If you are still reading, I’ll say what I worked on these last months.
I am trying to do my share on GIMP, to improve it globally, speed up the release of 2.10 and because I love GIMP. So I count 259 commit authorship in 2016 (60 in the last 3 months) + 48 as committers only (i.e. I am not the author, but the main reviewer of a patch which I pushed into our codebase). I commented on 352 bug reports in 2016, making it a habit to review patches when possible.
I have a lot of projects for GIMP, some of the grander being for instance a plugin management system (to install, uninstall and update them easily from within GIMP, and a backend side for plugin developpers to propose extensions), but also a lot of ideas about the evolution of the GUI (this should be discussed topic-per-topic on later blog posts).
Also I have been starting to experiment with Flatpak so that GIMP can provide an official release for GIMP. For years, our official stance has always been to provide a Windows installer, a OSX package, and GNU/Linux… yeah grab the source and compile or use the outdated version from your package manager! I think this situation can be considerably improved with Flatpak and similar technologies which were born these years.
Animation in GIMP
As explained already, I took the path of writing it as a plugin rather than a core feature. Anyway GIMP is only missing a single feature which would make it nearly as powerful: bi-directional notification (basically currently plugins don’t get notified when pixels are updated, layers are renamed, moved or deleted, images closed…). That’s actually something I’d like to work on (I already have a stash somewhere with WIP code for this).
The animation plugin currently has 2 views:
This actually corresponds to the very basic animation logic of 1 layer = 1 frame, which is very common by people making animated GIF (or MNG/WebP now), except with a nice UI to set each image duration (instead of tagging the layer names, a very nasty user experience, feature hidden and found only on some forums or old tutorials), do basic compositing and even comments on vignettes if-need-be. All this with a nice preview in real-time!
This is the more powerful view where you can compose a frame from several images, often at least a background and a character. In the above example, the cut is made from 3 elements composed together: the background, the eagle and the marmot.
You may usually know more of the “timeline” style of view, which is basically the same thing except that frames are displayed as horizontal tracks. I tried this too, but quickly shifted to this much more traditional view in the animation world, which is usually called an x-sheet (eXposure sheet). I found it much more practical, allowing commenting more easily too, easy scroll, and especially more organized. There is a lot you don’t see in this screenshot, but this view is really targetting a professional and organized workflow. In particular with layers properly named, you can create animation loops and line tests of dozens of images, with various timings, in a few clicks.
I am also working on keyframing for effects (using animated GEGL operations) and camera movements.
Well there is a lot done but definitely a lot more I am planning to do there, which takes time. I will post more detailed blog posts and will push the code on a branch very soon (probably before Libre Graphics Meeting this year).
That’s all, folks!
And so that’s it for this end-of year report from ZeMarmot team! I hope you appreciate the project. And if so and can spare the dime (or haven’t done so yet), I remind the project accepts any amount on the links given above. Some people just give 1 Euro, others 15 Euro per month. In the end, you are all giving life to ZeMarmot!
