Hey, first time poster here.
I've been using Premiere for several years now, but tonight I really sat down with CS5 and started to edit that latest episode of my webseries. However, I quickly found out something disturbing. As I was editing two of the mono audio tracks, I tried to target a track and paste in Track 5. However, it decided to post above it, in Track 4, the first of the two mono tracks.
Before you ask: Yes. I deselected Track 4, I selected Track 5, and they are both mono.
What's the deal?
This was most likely because the Targeted Audio Track did not match the channel-count of the Copy/Paste Audio.
Look at the little "speaker" icons in the Targeted Track Headers. Two "speaker" will equal 2-channel. If you have 1-channel, you need 1-channel Tracks. Drag to the Master, and PrPro will create the necessary Tracks for you.
Hey, uh... found out what it was, and I feel like a dunce. As it turns out, I had the FIRST stereo track targeted. Meaning, it would post to the first mono track only.
Again, I feel like a total rube. Thanks for the help, though!
