I need to insert a clip into an existing video/audio track, and I'm not sure how to do it. There are a couple of scenarios:
1. I want to insert a new clip of arbitrary length at the very beginning of the video. The existing video and audio tracks are moved to the right together, the distance moved is the size of the inserted clip. They are moved together, so synchronization is not lost.
1b. As 1a, but a text/background effect (assume would work the same).
2. As (1), when inserting at an arbitrary location anywhere in the file. All clips to the right of the insertion point are moved right the length of the insertion, and any audio is kept in synch with the pre-exisiting video.
Simple questions I know; but everything I've tried either doesn't work or causes disaster.
Thanks!
