What EbSynth does

EbSynth is VFX software for creative video transformations, retouching, and rotoscopy. Its core workflow is built around editing one or a few keyframes and letting the software propagate those changes across the rest of the video.

The product is aimed at artists who want to restyle footage, paint over performances, fix and colorize video, or automate parts of a visual-effects workflow without traditional frame-by-frame tracking. The site also offers a Studio plan for offline use and a browser-based experience for general projects.

Core features

Keyframe-driven video editing

Paint a small number of keyframes and let EbSynth propagate those edits across the rest of the shot to create stylized video transformations.

Retouching and colorization

Use the software for touch-ups, digital makeup, and colorizing without manual frame-by-frame tracking.

Paint-over animation

Create hand-drawn animation effects from performance footage by painting keyframes and letting the software synthesize the in-between frames.

Web-based rendering workflow

Work with a browser-based flow that recommends Chrome for memory-intensive projects and long or high-resolution videos.

Plan-based output options

Choose export options that vary by plan, including MP4 output on Free and PNG sequence output plus up to 4K render on Pro.

Studio workflow for offline production

Use the Studio tier for offline processing, command-line automation, and dedicated support.

Common use cases

Hand-drawn animation from video
Paint over a performance or live-action clip to turn it into a stylized animation while keeping the motion from the original footage.
Video retouching and colorization
Replace manual tracking for shot cleanup, digital makeup, and color work by editing representative frames and letting the software carry the result through the clip.
Offline production workflows
Use the Studio plan when a project needs offline processing, no uploads, or command-line automation in a production environment.
Fast visual experimentation
Iterate on visual ideas quickly by adjusting a few frames and re-running the synthesis instead of reworking the entire shot frame by frame.
Multi-track shot correction
Prepare keyframes carefully for difficult motion, then split a shot into separate tracks for areas like background, face, or eyes when different timing is needed.

Pros and Cons

Pros

Lets you change a video by editing keyframes instead of every frame.
Supports several VFX-oriented workflows, including paint-over animation, touch-ups, digital makeup, and colorizing.
Offers a free plan for trying the product.
Provides a Studio option for offline processing, privacy, and command-line automation.
Documents a practical getting-started path with a tutorial and workflow tips.

Cons

The public pricing page at `/pricing` returns a 404, so plan details are only visible on the site’s main pages.
Chrome is recommended for the best experience, which suggests browser choice matters for larger projects.
The standard web workflow uploads video and keyframes for rendering before deleting them afterward, so it is not fully offline unless you use Studio.

FAQ

How do I get started with EbSynth?

EbSynth is primarily a web-based workflow for changing video by editing keyframes. The site also offers a 10-minute tutorial and recommends Chrome for the best experience, especially on larger or higher-resolution projects.

Is EbSynth AI?

The site says the core propagation workflow does not use AI. It uses a texture-synthesis algorithm that works from your video and keyframes, though there is an optional AI feature called Generate Image for creating keyframes.

Does EbSynth keep my projects on its servers?

For the standard web workflow, your projects stay on your computer while video and keyframes are temporarily uploaded to EbSynth’s servers for rendering and deleted after results are returned. The Studio plan is described as fully offline with no uploads.

What plans does EbSynth offer?

EbSynth lists a free plan for trying the product, a Pro plan for higher-resolution exports and more generated images, and a custom Studio plan for offline use, command-line automation, and dedicated support.

Can I contact EbSynth about Studio or support?

Yes. The contact page provides a general support form, and the Studio page invites users to contact the team at studio@ebsynth.com for Studio inquiries.
