video-use Treats The Transcript As The Agent's Primary Video Interface

video-use compresses video into a word-timestamp transcript, requests visual composites only at decision points, emits an edit decision list, renders, and checks cut boundaries before review.

In one minute

The agent does not ingest every frame. It reasons over a compact transcript with diarization and audio events, asks for timeline composites on demand, snaps cuts to word boundaries, renders through FFmpeg, and runs a bounded self-eval loop.

video-use makes a strong interface choice: the agent primarily reads video instead of watching every frame. One transcription pass produces word timestamps, speakers, and audio events in a compact text view. Visual filmstrips and waveforms are generated only for ambiguous pauses, retake comparisons, and cut-point checks.

The workflow is explicit: inventory footage, propose a strategy, wait for approval, transcribe and pack, reason over the material, write an edit decision list, render, and self-evaluate the result at every cut boundary. The repository uses FFmpeg for production work and can add overlays through HyperFrames, Remotion, Manim, or PIL.

This is a useful multimodal compression pattern. A structured representation carries most decisions; expensive visual inspection is demand-driven; the final artifact is still rendered and checked. It lowers context cost without pretending that transcript alone captures every visual fact.
