I can go to other parts of the video, and the audio plays fine, both the audio embedded in the video clip and a third audio file in the Soundtrack track (44.1 HZ .mp3).
I'd be inclined to:
- convert that MP3 to a .wav 48Khz 16-bit (the free Audacity can do that). This puts the sound to the ideal format for PRE.
- and use the converted track on a higher Audio Track. The Soundtrack and Narration tracks can, for no known reason, mess up Audio across the whole timeline.
Insanity is hereditary, you get it from your children
I agree with Neale, and by choosing the 48KHz 16-bit, one then rules out the Sample-Rate difference of 44.1KHz, though PrE should be able to Conform from that common (CD Audio) Sample-Rate.
Awesome -- thanks, guys.
I removed everything from the Timeline to start over. Converted the iTalk AIFF clip and the .mp3 soundtrack to 48kHz WAV files with Audacity, put them back in new audio tracks, synced up just as before -- including trimming -- and everything seems to be working. Hooray! Now we'll see if it can handle that with multiple synced clips. . . .
In a way it doesn't make sense since it's worked fine with mixed 44.1 and 48kHz files before, but maybe it had something to do with that Soundtrack track.
Usually, PrE can Conform 44.1KHz 16-bit just fine. That is the CD-Audio spec., but if you are converting, then just setting that to 48KHz 16-bit gets one even closer to the ultimate.
