Trim clip to desired length

By end of day, trim the 00:00:12 Beach_3 clip to start at 00:00:02 and end at 00:00:09 so the usable segment is seven seconds. Confirm the trimmed clip retains the original filename Beach_3_trim and is linked in the timeline for the Monday draft export.

Before trimming Beach_3, make the choice easy: show the waveform and a two-frame zoom around the 00:00:02 and 00:00:09 marks, note any jump cuts or audio spikes, and suggest whether a 1–2 frame fade or a one-frame J-cut would hide rough edges. Flag if trimming creates an odd phrase in the voiceover.

I trimmed Beach_3 to the intended 7 seconds, but the audio now sounds half a beat off from the lip movement. I don’t know whether I trimmed the wrong track or introduced a timing gap. Should I check for detached audio, linked track settings, or a timeline FPS mismatch first, and what precise steps do I follow to fix audio sync without redoing the whole trim?

I repeatedly have to re-trim clips because audio drifts or dialogue cuts awkwardly after earlier edits. Where am I losing time and what single edit habit should I adopt to stop chasing sync—e.g., always lock, mark in/out on the audio take, or trim with linked audio visible?
