EbSynth is a video style transfer tool developed by Secret Weapons that transforms video footage into hand-painted or stylized animation. Unlike generative AI tools, EbSynth uses a texture synthesis algorithm to propagate the style of a single painted keyframe across every frame of a video, preserving content at the pixel level for precise artistic control.
The tool has been used in professional productions including Richard Linklater's animated feature “Apollo 10½: A Space Age Childhood” and an animated sequence in Netflix's “Wednesday.” Beyond full video stylization, EbSynth is also used for rotoscoping, digital makeup effects, and other VFX tasks. The latest release, EbSynth 2, introduced improved synthesis quality and workflow features.
EbSynth is not a generative AI tool. It uses texture synthesis (the PatchMatch algorithm) to transfer your hand-painted style frame by frame, giving artists direct pixel-level control over the final output.
EbSynth is available as both a desktop application and a web-based interface. The original source code is also published on GitHub under a public domain license, making it accessible to developers and researchers who want to build on the technology.
Best EbSynth Alternatives in 2026
Whether you need a different approach to video style transfer, more AI-powered automation, or traditional motion graphics capabilities, here are the top EbSynth alternatives worth considering:
NemoVideo is an AI-powered video editing platform that automates editing, transitions, and effects through an agentic chat-based workflow. Ideal for creators who want to turn raw footage or images into polished video content without manual frame-by-frame work. Start free today.
Krita is a free, open-source digital painting application used by artists and animators. While it does not offer automated video style transfer, it excels at hand-painting keyframes that can then be fed into EbSynth or similar tools for frame propagation.
LensGo is a free AI-powered tool that lets users apply style transfer to videos using a single reference image. Unlike EbSynth's manual painting approach, LensGo uses AI models to generate stylized video automatically, making it faster but with less artistic control.
Adobe After Effects is the industry-standard motion graphics and VFX compositing software. It offers far more capabilities than EbSynth for general post-production work, including rotoscoping, keying, and motion tracking, though it requires a Creative Cloud subscription.
EbSynth Pricing Plans (2026)
EbSynth offers three pricing tiers, from a fully functional free plan to a custom enterprise option. Here is a breakdown of what each plan includes:
| Plan | Price | Key Features |
|---|---|---|
| EbSynth Free | $0 | All core features, no time limits, 720p HD export in MP4 |
| EbSynth Pro | $20/month | Up to 4K video export, PNG sequence output, priority processing |
| EbSynth Studio | Custom | Offline processing, complete data privacy, CLI automation, dedicated support |
| NemoVideo | Free / Premium | AI-powered video editing, agentic workflow, smart captions |

Does EbSynth Have a Free Version?
Yes. EbSynth offers a completely free plan with no time limits and no functional restrictions. The Free plan gives you access to all core style transfer features and lets you export finished videos at up to 720p HD resolution in MP4 format. There is no trial period — the free tier is permanent.
The main limitation of the Free plan is the 720p export resolution cap. If you need 4K output or PNG sequence exports for professional compositing workflows, the Pro plan at $20/month unlocks those capabilities along with priority processing. Additionally, the original EbSynth source code is available on GitHub under a public domain license, so developers can build and modify it freely.
NemoVideo lets you transform static art into dynamic videos, for free. AI-powered editing, smart captions, and more are included. Get started free.
How to Use EbSynth: Beginner's Guide
EbSynth's workflow is straightforward: you paint one frame, and the software handles the rest. Here is a step-by-step guide to creating your first stylized video.
Step 1: Prepare Your Video
Extract your source video into a PNG image sequence. Each frame should be saved as an individual PNG file in a dedicated folder. Choose a keyframe that reveals as much of your scene as possible — this will be the frame you paint over.
Step 2: Paint Your Keyframe
Open your chosen keyframe in a painting application like Krita, Photoshop, or Procreate. Paint over it with your desired artistic style. The keyframe should closely match the original footage in terms of composition — ideally it should be a direct overpaint of the video frame, not a completely new drawing.
Step 3: Run EbSynth and Iterate
Open EbSynth, drag your video frame directory into the video section and your painted keyframe into the keyframes section, then press “Run All.” Review the output — after a certain number of frames, the style may start to degrade. When this happens, pick one of the messy result frames, paint over it to fix it, and add it as an additional keyframe. Repeat until the full video looks consistent.

Best Video Style Transfer & Art Tools in 2026
The video art and style transfer landscape in 2026 spans everything from manual painting tools to fully automated AI platforms. Here are the standout options across different categories:
- EbSynth — Pixel-level video style transfer by painting a single keyframe. Free tier with full features. Used in professional film and TV productions.
- NemoVideo — AI-powered agentic video editing with chat-based workflow. Automates editing, transitions, and effects for polished video content.
- Krita — Free, open-source digital painting. Excellent for creating the hand-painted keyframes that EbSynth requires as input.
- LensGo — Free AI video style transfer using a reference image. Faster than EbSynth but with less manual artistic control.
- Adobe After Effects — Industry-standard motion graphics and VFX compositing. The most comprehensive option for professional post-production work.
- Friction — Free, open-source motion graphics software. A lightweight alternative to After Effects for basic animation and compositing tasks.
Does EbSynth Have an API?
EbSynth does not offer an official public API. The main product is a desktop and web-based application with a graphical interface. However, the Studio plan includes command-line automation capabilities, allowing batch processing and integration into production pipelines without a GUI.
For developers who need programmatic access to EbSynth-style video synthesis, several third-party Python libraries are available. ReEzSynth is a PyTorch-based rewrite with a clean Python API and custom CUDA extensions for high-performance synthesis. Ezsynth provides an importable Python library for both video stylization and image synthesis. There is also a ComfyUI-EbSynth extension for integrating EbSynth into ComfyUI workflows, and an AUTOMATIC1111 extension (ebsynth_utility) for combining Stable Diffusion img2img with EbSynth-style frame propagation.
