Full Reference

execute-edit

Reads edl.json and renders the video using FFmpeg through a 7-step pipeline: trim clips, concatenate, apply cross-dissolve transitions, overlay B-roll, insert title cards, normalize audio to -23 LUFS, and final H.264/AAC encode. All operations use copies in tmp/ — source footage is never modified. Output is output/rough-cut.mp4.
