EbSynth

Transforms videos by propagating edits from one or few keyframes using texture synthesis. EbSynth is VFX software for creative video transformations, retouching, and rotoscopy. The core propagation uses a texture-synthesis algorithm that matches patches from keyframes to video frames without external training data or generative models. An optional AI feature exists only for generating keyframes. Chrome is recommended, especially for larger projects, as it handles memory and processing more reliably than other browsers. The free plan includes the full core experience with no time or functional limits, though Pro unlocks higher resolutions and extras. Choose keyframes at clear poses, avoid mid-movement frames, separate moving elements into tracks, and use well-lit source video with visible texture for better optical flow. But high-res rendering and PNG sequence export require the Pro plan. Free works for standard resolutions. Projects stay on your computer. Temporary uploads occur for rendering and are deleted immediately afterward.
