Trim or edit uploaded video

I need the trimmed version of my May 8 livestream that cuts the 12‑minute broken audio at 00:37:15 through 00:49:15 and removes the 3‑minute dead space at the end, then export a new upload-ready MP4. Keep the title, description and tags intact and set visibility to unlisted for review by Friday.

Before I send this trimmed file to the editor and channel manager, make the cut obvious to a reviewer: show a before/after timeline snapshot, surface the total removed duration up top, flag any abrupt audio transitions and recommend two brief B‑roll options to mask the cut.

We uploaded the May 8 livestream and QA found distorted audio from 00:37:15–00:49:15. The channel manager, Priya, needs an honest assessment: can this be repaired with noise reduction and EQ or must we excise and stitch? I don’t have time to re-record. Tell me the likely technical diagnosis and the best next move so I can tell Priya which version to review today.

Over the last six livestreams I keep losing time fixing audio glitches and making last‑minute trims that look amateur. Editors lose faith because there’s no consistent policy and I keep approving rushed fixes. Recommend one habit or checklist I can enforce that stops these emergency trims and preserves audio quality across the next eight shows.
