Hi. I'm working on my first movie in FCP. It is old footage from the 60s that I had telecined to DV. The imported video has audio tracks, but there is no sound on them as they were super8 with no audio. I'm importing mp3 files to play alongside the video. They end up going on audio tracks A3 and A4. (old christmas songs, as it is old christmas footage). I want to put audio transitions between these clips on A3 and A4, but I do not seem to be able to. I'm only able to add transitions between video clips and the empty audio tracks on A1 and A2. How can I add audio transitions between the mp3 files I'm laying down on the extra audio tracks? Thanks in advance.
