Pro4X, Windows 7. multi camera mode, have aligned 3 video tracks, imported a file, first as wav, second attempt as mp3. I pull it onto the 2nd track and it does play, though ends well before the clip ends.

It's much shorter than the video length .. how do I stretch it to go to the end of the video clips?

Should I be saving it as another format as to line up with duration of video?

Thank you, Paul
