What is EbSynth?
EbSynth is a video special effects tool. Its official website describes itself as "VFX software for retouching, rotoscoping, and stylization", and its core feature is "Change your video by editing one frame" — just draw the key frames well, and leave the rest to it to propagate along the timeline. It was developed by Šárka Sochorová and Ondřej Jamriška at Secret Weapons.
Who is it for?
- Animators and independent creators who want to convert live-action footage into hand-drawn style.
- Post-production staff who need frame-by-frame retouching and error removal.
- Restoration specialists who colorize black-and-white or old footage.
- Production teams with confidentiality requirements who cannot upload materials to the cloud (Studio local solution).
- Art directors and storyboard designers who need to quickly test effects in a browser.

How to use EbSynth
- The official website's FAQ clearly states: The propagation of keyframes along the timeline does not use AI, but a texture synthesis algorithm.
- It only relies on your videos and key frames, and does not use generative models trained on external datasets.
- The more complete and aligned the keyframes are with the original frame structure, the more stable the propagation results will be.
- only drawing partial areas is prone to drifting.
- For large projects, it is recommended to use Chrome and confirm that a dedicated graphics card is used on the laptop.
- The official website states that this is the most reliable option for memory-intensive processing.
- If your project involves sensitive information, prioritize the locally run solution of Studio.
- Subscription and cancellation rules are subject to the official website's specifications.
- cancellations take effect at the end of the current billing cycle.
- prices are subject to change.
- please re-verify before commercial use.
