Scarlet

Scarlet is an open-source AI video editor for macOS and Windows. Tell Claude Code or Codex what you want to change, by voice or in writing, then play the edit on your timeline. Your original footage stays intact.

Scarlet works especially well on dialogue-heavy recordings. Start with an interview, a video podcast or a talking-head take. Ask it to shorten long pauses, remove a repeated phrase or keep the clearest take of an answer. Tell it where the timing matters to you, such as a pause before a punchline.

“Tighten the pause before ‘three things.’ Let me hear it both ways.”

Scarlet renders just the affected section so you can hear what a change sounds like in context. Requested edits go on the working timeline. Suggestions wait for you to apply them. For a first cut of a whole interview, you can jump straight to the cuts the agent flags for a second listen.
