EbSynth

What EbSynth is

EbSynth is VFX software for retouching, rotoscoping, and stylizing video. You provide a guiding video and keyframes, and it carries visual changes across the sequence using texture synthesis rather than generative models trained on external datasets. Uses include painting over footage, retouching or colorizing it, and adding painterly texture to animation. An optional Generate Image feature uses SDXL 1.0 to create keyframes. The free plan includes core functions, 720p export, and MP4 output. Pro costs $20 per month and adds 1080p and 4K exports, PNG output with alpha, and priority processing. Studio costs $200 per month per seat, with local processing, a Windows desktop app, and command-line access for offline pipelines. For browser projects, EbSynth recommends Chrome, especially for large, long, or high-resolution work, and a laptop’s dedicated graphics card. Videos and keyframes are temporarily uploaded for rendering and deleted after results are returned; the site says they are not shared or used for AI training. EbSynth is available on desktop devices.
