Frequently Asked Questions
What is EbSynth used for?
EbSynth transfers the style of one painted keyframe onto every frame of a video, guided by the original footage. It creates the hand-drawn rotoscope look used in films, music videos, and AI-animation workflows, and it is completely free.
How do I use EbSynth with Midjourney or Flux?
Generate a stylized keyframe with an AI image tool, then paint or clean it, and use EbSynth to propagate that style across your footage. This two-step workflow — AI keyframe plus EbSynth — is the most popular way to get stylized AI animation in 2026.
Is EbSynth good quality?
For the rotoscope / painted look it is excellent — that is its purpose. It is not a photoreal video enhancer; it trades realism for a consistent artistic style. Quality depends heavily on how carefully you keyframe and how similar the footage is to the style.
Is EbSynth free?
Yes. EbSynth is completely free and open-source. It runs locally on your machine, which also means your footage never leaves your computer.
What is the best tool for AI video style transfer?
For the painted-keyframe look, EbSynth is the standard and it is free. For prompt-driven restyling, tools like Runway offer style transfer inside a full editor. For precise control and zero cost, EbSynth remains the pick.
