Beat Sync Video Editing

You give it a video file, an audio track, and a description of what you want, and it uses Gemini's multimodal API to generate a beat-synced edit plan that maps video clips to the music's rhythm. The workflow is remarkably straightforward: a bash script uploads both files to Gemini, gets back a JSON EditPlan with timestamps and clip selections, then pipes that through validation and FFmpeg filter generation scripts. The whole thing spits out a proper filter_complex command for rendering. It keeps uploaded files cached for 48 hours by default so you can iterate on prompts without re-uploading, which is smart. If you've ever manually scrubbed through footage trying to find moments that hit on beat drops, this automates exactly that part.
