Index the actual source
Media indexing and transcripts establish stable time references. The agent can search the source without guessing from filenames or a short prompt.
Propose moments with reasons
Candidate moments carry source ranges and editorial rationale. A creator can inspect the surrounding context before choosing a direction.
Build a real vertical edit
Selected ranges become semantic sequence commands. Reframing, captions, text, music, dialogue treatment, pacing, and delivery specs remain editable.
Verify the persisted result
The workflow re-reads the project after apply, checks the intended ranges and output shape, and retains an undo path.
