EbSynth vs Katana

EbSynth is VFX software for retouching, rotoscoping, and stylizing video. You provide a guiding video and keyframes, then it carries visual changes through the sequence with a texture-synthesis algorithm. Listed uses include painting over footage, retouching or colorizing video, and adding painterly texture to animation. The optional Generate Image feature creates keyframes with SDXL 1.0. The Free plan costs nothing and includes core functions, 720p export, and MP4 output. Pro costs $20 a month and adds 1080p and 4K exports, PNG with alpha, and priority processing. Studio costs $200 a month per seat, with local processing, command-line access, a Windows desktop app, and footage kept on your machines. Web rendering temporarily uploads videos and keyframes, then deletes them after returning results.
