Dover, Delaware, USA
What it is
EbSynth is desktop VFX software for retouching, rotoscoping, and stylizing video. Provide a guiding video and keyframes, and it carries visual changes through the sequence using texture synthesis—not generative models trained on external datasets. Described uses include painting over footage, retouching or colorizing it, and adding painterly texture to animation. An optional Generate Image feature can create keyframes using 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 and provides local processing, a Windows desktop app, and command-line access. The site says browser uploads are temporary and deleted after rendering; it also says videos and keyframes are not shared or used for AI training. Chrome is recommended for larger or demanding browser projects.
