EbSynth

EbSynth is VFX software for creative video transformations, retouching, and rotoscopy

EbSynth lets video artists change an entire clip by editing a single frame. You paint or retouch one keyframe and the software propagates that change across the timeline, which removes the manual tracking normally required for touch-ups, digital makeup, and colorizing. The same mechanism turns a filmed performance into hand-drawn animation or adds painterly texture to line art.

Notably, the makers say the keyframe propagation does not use AI; it is a texture-synthesis algorithm that works only from your video and keyframes, even though the tool sits in this directory's video generation category. EbSynth is made by Šárka Sochorová and Ondřej Jamriška at Secret Weapons, its FAQ covers which browser to use, and a ten-minute tutorial shows how to get started.

The free tier with paid plans is spelled out on the site: the free plan includes all core functions with 720p MP4 export, the Pro plan adds 1080p and 4K exports, PNG with alpha, and priority processing, and a Studio plan provides a Windows desktop app so footage never leaves your machines. Animators and VFX editors who want to skip frame-by-frame work should watch the tutorial and try the free plan first.
