# EbSynth > VFX software that applies the edits you make on one video frame to the rest of the shot. EbSynth is visual effects software that restyles or retouches a video from a single edited frame. EbSynth is used by painting or correcting one keyframe and letting the program carry that look across the other frames, which suits hand-drawn animation, digital makeup, colorizing and rotoscoping. It runs in a desktop browser, with a free plan available. **Best for:** Artists and editors who want to paint, retouch or stylize a shot by working on a few keyframes instead of every frame. - Official site: https://ebsynth.com - Listed in: [Video Editing](https://trendhub.net/ai-tools/category/video-editing), [AI Video Generator](https://trendhub.net/ai-tools/category/ai-video-generator) - Last checked: 2026-10-09 (facts taken from ebsynth.com) - Source page: https://trendhub.net/ai-tools/ebsynth-restyle-video-editing-one-frame ## Key facts - Platforms: Web, Windows - Pricing model: Freemium - Free plan: Yes - Made by: Secret Weapons ## What is EbSynth? EbSynth is a visual effects program that changes a whole video based on edits made to a single frame. You paint, retouch or restyle one keyframe, and the software carries that change through the remaining frames of the shot. Typical jobs are turning live footage into hand-painted animation, digital makeup and touch-ups, colorizing, rotoscoping, and adding painterly texture to line art. According to the site's FAQ, the propagation step is a texture-synthesis algorithm that works only from your footage and keyframes, not a generative model; an optional Generate Image feature uses AI to create keyframes. EbSynth runs in a desktop browser, with Chrome recommended, and is unavailable on mobile devices. Three plans exist: Free with 720p MP4 export, Pro with 1080p and 4K export, PNG output with alpha and priority processing, and Studio, a Windows desktop app that processes footage locally. ## Key features - **Keyframe Propagation**: Spreads the look of a painted or edited frame over the whole clip using optical flow from the source video. - **Paint Over Video**: Turns a filmed performance into hand-drawn animation once you paint the keyframes. - **Retouch and Colorize**: Applies touch-ups, digital makeup or colour to moving footage without manual tracking. - **Multiple Video Tracks**: Lets separately moving parts, such as a background, a face or the eyes, be handled on their own tracks with different keyframe timing. - **AI Keyframe Generation**: Offers an optional Generate Image function for producing keyframes with AI. - **Export Options**: Outputs MP4 at 720p on the Free plan, and 1080p, 4K and PNG sequences with alpha on Pro. ## Use cases - **Hand-Painted Animation**: Paint a handful of frames of live footage and let the remaining frames follow the same brushwork. - **Beauty and Clean-Up Work**: Fix skin, remove blemishes or add makeup on one frame and have it hold through the shot. - **Colorizing Footage**: Add colour to a keyframe of black-and-white material and extend it over the clip. - **Texturing Line Art**: Give a line-drawn animation a painterly finish from one carefully painted frame. - **Confidential Studio Projects**: Process footage on local Windows machines with the Studio plan when files cannot leave the building. ## Things to know - **Desktop only**: The app does not run on phones or tablets, and Chrome is the recommended browser, particularly for long or high-resolution projects. - **Temporary uploads for rendering**: Video and keyframes go to EbSynth's servers for rendering and are removed afterwards; the Studio plan processes everything offline. - **Core algorithm is not generative AI**: Propagation uses texture synthesis driven by your own footage and keyframes; AI is involved only in the optional keyframe generator. - **Subscriptions end with the billing period**: A cancelled plan remains active until the current billing period is over. ## FAQs ### What is EbSynth? EbSynth is a VFX program that transfers the edits made on a keyframe to the other frames of a video, covering stylization, rotoscoping and retouching work. ### What is EbSynth used for? EbSynth is used to turn footage into painted animation, apply retouching or digital makeup, colorize video and add texture to line art. ### Is EbSynth AI? Partly. EbSynth's FAQ says keyframe propagation is a texture-synthesis algorithm that does not rely on generative models trained on outside data, while the optional Generate Image feature does use AI. ### Is EbSynth free? Yes. EbSynth has a Free plan with all core functions and 720p MP4 export, and the site says it has no time limit. Higher resolutions, PNG output and priority processing need the Pro plan. ### Does EbSynth work on mobile? No. EbSynth states that it is available on desktop devices only, and it recommends Chrome as the browser. ### Does EbSynth store my projects? No. EbSynth says projects stay on your computer; video and keyframes are uploaded temporarily for rendering and deleted after the result is returned. ### Who makes EbSynth? The company behind EbSynth is Secret Weapons, where it was created by Ondřej Jamriška together with Šárka Sochorová. ### How much does EbSynth cost? EbSynth lists Free, Pro and Studio plans.
