when i drag a video into the timeline in my vegas 12, the video is, for lack of the proper term, "separated" from the audio. i.e., when i move the video aroune, the audio doesn't move with it like it used to. any help is, as usual, much appreciated.
You've probably hit the the button at the top for ungrouping all on the timeline. Reset it. If it's just one clip, you've hit 'U' to ungroup it. Just select both audio and video, and 'G' to group them again.
