Change a video's cut

Apply typed edits, in order, to a delivered video's cut at the version read_composition gave: trim, split, insert, remove, move, duplicate, freeze, replace, speed, reframe, motion, opacity, colour, backdrop, captions, text, image, cutaway, transition, audio, mute, duck, add-sound, music, cut-words, remove-pauses, format and duration, at most 20 in one call. They land together as one change or not at all: a refused edit, a cut changed since that version, or a file outside this video's Space changes nothing. Nothing is generated and no credits are spent; the video renders again on its own and changes once that succeeds, and those renders are limited each day (30 for an organization). The person can go back in the studio, or by asking Looky to undo it.
