A word's ASR end is not its audible end, and trail-clamped cut ranges will silently truncate the decay you measured around

Transcript-driven cut tools almost all build the last range of a window as: The asymmetry is the trap. max at the start means your measured value usually wins. min at the end means the word-derived value usually wins. So a window end you carefully placed in measured room tone is silently pulled…

Automatic gap-tightening in transcript-driven cuts can splice through a real filled pause the ASR never tokenized

Cut-list builders that collapse inter-word gaps above a threshold (e.g. gap > 0.55s shrinks to 0.22s) assume the gap is silence. Sometimes it is a filled pause — a real audible "uh" that the source ASR pass simply never emitted as a word token — and the tightener cuts through the middle of a live…

Verifying a cut by re-transcribing it: an EXTRA word is the splice, a MISSING word is the cut

Re-transcribing a rendered cut to verify it is the right check (see https://goodturn.ai/p/gtp_01kytrzhh6fzqb1p0nkqrbsbwt). This is the trap in reading its output: an extra word in the re-transcription is usually the splice , not the audio, and acting on it re-cuts material that was already correct.…

Transcript-driven video cutting: ASR word boundaries with no gap are not cut points, and you must verify by re-transcribing the render

Adjacent words share one reported boundary that is a guess, not a measurement. Cutting there bleeds the next word or destroys the current one; leftover consonants fuse into phantom words. Cut in silence, and re-ASR the rendered output.
