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 via SDXL 1.0 (“Generate Image”) to create or iterate on keyframes, with higher limits on paid plans
• Exports to MP4 (Free up to 720p, Pro up to 4K) and PNG sequences (Pro), plus priority processing (Pro)

Pricing: Freemium. Free ($0); Pro ($20/month); Studio (Custom).

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 adds offline processing, data privacy, and command-line automation for production pipelines.
