check timeline
Check a cut before rendering: the structure and the sound in one read. Structure, from the document, instant: stretches that render black, a clip buried under a full-frame one above it, a trim past the end of its file, missing media, muted sound, text too small to read on a phone, open notes. Sound, measured once per file and kept: each clip’s loudness and peak as the timeline plays it, the clips that will distort, and whether the speech sits where platforms normalise to (level_audio acts on that); audio: false skips it. It says what is scheduled, never how a frame looks: inspect_timeline at a flagged range is the other half. Free, except measuring sound the first time: cloud processing.
