Quicktime Player help:
With QuickTime Player you can quickly remove a portion of the beginning or end of a movie or a movie clip to make it shorter or remove unwanted content.
I want to remove the portion starting at 03:08 and ending at 03:49 of the movie, preferably through an applescript like the following:
tell application "QuickTime Player" activate trim document 1 from 0 to (4 * 60 + 41.75) end tell
Am pretty sure QT PRO can do it.
