EbSynth review
A focused tool for propagating stylized edits across video sequences.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
EbSynth is visual-effects software for artists and teams that want to propagate visual changes from selected keyframes across video sequences. Users provide a guiding video and edited keyframes, and the software synthesizes the intervening frames. Its workflows cover video retouching, digital makeup, colorizing, rotoscoping, painterly animation, and hand-drawn animation from painted keyframes. The product is available on the web, with Studio also providing a Windows desktop application.
The published plans show a freemium structure. Free includes all core functions, 720p video export, and MP4 format output. Pro costs $20 per month with monthly billing and adds 1080p and 4K exports, PNG output with alpha, and priority processing. Studio costs $200 per seat per month with monthly billing and adds local execution, a Windows desktop app, footage that never leaves your machines, and full data privacy. This makes Free suitable for lower-resolution work, while Pro fits projects needing higher-resolution or alpha-enabled output. Studio is aimed at organizations with offline processing and privacy requirements.
EbSynth’s main strength is its focused keyframe-propagation workflow, supported by optical-flow-based tracking guidance and optional AI-generated keyframes through Generate Image. That focus suits stylized retouching and effects work, including painterly and hand-drawn treatments. It is less suitable for buyers seeking a broad visual-effects suite or wider platform coverage, because its listed platforms are web and Windows and its workflow centers on guiding video plus edited keyframes. Choose EbSynth for targeted stylization, retouching, rotoscoping, and keyframe-driven transformations; choose an alternative when a broader production environment is the priority.
