Hi all!
We're a team of friends who do research in computer graphics and turn it into artistic software. We love VFX and traditional animation and we want to give you tools that support your creative work and reduce some tedious tasks. In return, we would like to see more hand-drawn movies in theatres. Just kidding, we know that takes two lifetimes and a firstborn. Actually...
Our first 'secret weapon' is called EbSynth and it automates rotoscope. In arbitrary style. Paint the keyframes, EbSynth does the in-betweens. You could also think of it as free 2D tracking. Change the hair color in one video frame, EbSynth turns you into Billie Elish for the rest of the footage. You can also add texture or shading to a flat 2D animation or enhance 3D renders with brush strokes.
You can try it out, there a free beta to download: ebsynth.com
Have fun! :)
