EbSynth

Overview

EbSynth is an innovative VFX software designed to transform videos by editing just one frame. Developed by VFX duo Šárka Sochorová and Ondřej Jamriška, EbSynth empowers artists and creators by putting creative control directly into their hands. Rather than manually rotoscoping or tracking every frame, EbSynth uses a texture-synthesis algorithm to propagate your edits from a single keyframe across a video timeline, enabling seamless hand-drawn animations, effortless video retouching, and fast colorizing.

This software streamlines creative workflows by allowing users to paint over or digitally alter a keyframe, then EbSynth automatically transfers those changes onto the adjacent frames, eliminating tedious manual tracking or frame-by-frame editing. It supports projects from HD to 4K resolution (depending on the plan) and is compatible with MP4 and PNG sequence outputs. EbSynth is ideal for artists, filmmakers, animators, and VFX professionals seeking to breathe new life into their video content with minimal effort.

Key Features

• Single Frame Editing: Change your video’s look by editing just one frame; EbSynth handles seamless propagation across the timeline.
• Hand-Drawn Animation: Turn live-action footage into stylized hand-painted animations by simply painting over keyframes.
• Fast Retouching & Colorizing: Perform digital makeup, touch-ups, and color adjustments without manual rotoscoping or tracking.
• Texture-Synthesis Algorithm: Uses a pure texture synthesis approach (not generative AI) for accurate and reliable keyframe propagation.
• Optional AI-Assisted Keyframe Generation: Generate keyframes with an AI tool to speed up the creative process, with manual correction options.
• Multiple Export Formats: Export final videos in MP4 format or as PNG image sequences for flexible post-processing.
• High Resolution Support: Export up to 4K resolution in Pro and Studio plans.
• Offline Workflow Option: Studio plan offers complete offline processing for absolute data privacy and command-line automation.
• Priority Processing: Pro and Studio plans provide faster rendering and dedicated support.
• Cross-Platform Compatibility: Works best with Chrome browser and can leverage dedicated graphics cards for optimal performance.

Use Cases

• Creative Animation: Artists can convert video performances into beautiful hand-drawn animation sequences by painting over keyframes. This opens new storytelling possibilities for short films, music videos, and experimental projects.
• Video Retouching: Digital makeup artists and video editors can quickly fix blemishes or alter appearance without tedious frame-by-frame editing or tracking.
• Colorization: Bring black-and-white footage to life or adjust the color palette of digital footage effortlessly.
• VFX Production: Fewer manual steps for rotoscopy and texture replacements reduce production time while maintaining professional quality.
• Concept Exploration: Rapidly visualize different visual ideas and outcomes by painting over keyframes, enabling fast creative iterations.

FAQ

Is EbSynth AI? No, EbSynth’s core functionality uses a texture-synthesis algorithm based solely on your video and keyframes. It does not rely on generative AI trained on external datasets. The optional keyframe image generation feature uses AI but only assists in creating keyframes.

Which browser is recommended? EbSynth performs best on Google Chrome, especially for large or high-resolution videos. Chrome offers better memory management and supports dedicated GPU usage on laptops for optimal performance.

Are my projects stored on the cloud? Your projects remain private and local. Videos and keyframes are temporarily uploaded to EbSynth’s servers for rendering and deleted immediately after processing. For fully offline workflows, the Studio plan ensures no uploads occur.

Can I try EbSynth for free? Yes, the Free plan lets you test full core functionality with 720p HD video export in MP4 format. For higher resolutions, more keyframes, and additional export options, upgrade to Pro or Studio plans.

How do I get the best results?

• Start with a strong, clear keyframe.
• Add additional keyframes to fix broken areas.
• Choose keyframes during clear, stable poses rather than mid-motion.
• Align shapes in keyframes to the video frames to avoid artifacts.
• Use keyframes with transparent backgrounds to isolate elements.
• Divide the shot into independently moving parts when needed.
• Correct AI-generated keyframes manually if there are artifacts.

EbSynth unlocks new workflows for artists and video professionals by combining the power of frame-by-frame animation with the speed and automation of modern VFX technology. Whether you want to create hand-crafted animations or streamline complex video edits, EbSynth is your secret weapon to transform videos by changing just one frame.
