Kinda, it required central alignment. You can freely move separate frames with mouse to manually set any kind of alignment, and probably more, I don't know about all options yet. And of course CC has its own effects that may help to make better animations, after all it was made to create animations not only from sprites sheets.
I couldn't figure out the Animation CC BS, peace of sh!t, sorry excuse for a software
We don't need it anyway, we're making movies, not flash animations so for us it's either AE or Premiere.
I don't think we have a better option than using grayscaled animation as alpha. I suppose a pro artist could make a perfect alpha webm manually, but that's an overkill.
AE makes a movie from png files with 3 clicks of a button and a
perfect mask (I mean it, perfect one) with another 5 clicks. Two resulting files (movie + mask) turn out only slightly smaller than the original .pngs but I haven't looked into optimization yet.
1) Get After Effects.
2) Get Media Encoder.
3) Get .webm plugin for Media Encoder.
4) Import .png files into AE. Don't use sequence import, just the files. Create a composition (here you click the sequence check-button) from the files using the largest file for size (manually look for it..., there might be a script for this but I haven't looked for on yet).
5) Make sure FPS/Alignments are to your liking (FPS is a bitch and there doesn't seem to be an option to setup alignments vs the canvas for all files properly
).
6) Export the movie to ME.
7) Go to effects and under Channel, pick Set Channels. Set Red Channel to Alpha and turn off Green, Blue and Alpha Channels.
8 ) Export the mask to ME.
9) Setup the files in ME so the format is webm. Take parameters from the original file. Bitrate on Alpha channel can prolly be low to beat down the size a bit.
I've tested it in Ren'Py already, it works great and looks really, really good but unless there is a better way to optimize webms, we can just use Ren'Py animations directly, especially in cases with smaller files.
Afterthought... maybe we can remove alpha channel from movie. It's prolly useless. If that can improve the size...
