EbSynth

EbSynth is a web-based VFX tool for creators, artists, and VFX professionals who want to transform video by editing one or more keyframes and propagating those changes across an entire shot.

Key capabilities include:

• Keyframe propagation using optical flow and a texture-synthesis approach (not generative AI) to preserve texture coherence, contrast, and detail while applying painted edits across frames
• A Photoshop-like editor with timeline, layers, brushes, and masks for selective stylization, retouching, digital makeup, colorization, and rotoscoping workflows
• Optional AI keyframe generation (“Generate Image”) to create or iterate on keyframes
• Exports to MP4 (Free up to 720p, Pro 1080p and 4K) and PNG with alpha (Pro), plus priority processing (Pro)

Pricing: Freemium. Free ($0, all core functions, 720p MP4); Pro ($20/month); Studio ($200/month per seat, local Windows desktop app); custom deals on request.

What makes it notable: it focuses on fast, controllable keyframe-driven video stylization where propagation does not rely on training-data-based generative models, and the Studio tier runs EbSynth locally on Windows so footage never leaves your machines, with full data privacy for NDA-bound productions.
