I can't believe Premiere doesn't create TWO tracks when dragging it in the timeline.
I have an audio track that recorded boom plus lav mic on set... when I drag the audio clip in the timeline it makes one track with the boom _ lav mixed into one. This is obv. no good. I know how to make the stereo file mono, having both tracks in the timeline, but the issue is I've alreadt started editing quite a bit...
If I change the audio from stereo to mono now, it won't affect anything in my edit. I don't want to start over, so is there a way to fix this and get the audio files seperated and to be mono tracks?
You cannot change audio that is already inserted into the timeline.
Modify all your audio in the project window.
Select clip in the timeline, hit F and drag from Source Monitor into timeline.
As @Ann Bens mentioned, you cannot change the audio at this point with a magic button. But with a combination of a few shortcuts, it shouldn't take longer than a couple of minutes to change all the audio clips into what you want.
1 - Modify your clip's audio channels as desired.
2 - Go to Edit > Preferences > Timeline, make sure to check the "Set focus on timeline after overwrite".
3 - On your timeline, select only the track containing the audio you want to change.
4 - Move the playhead to the first frame of the first clip.
5 - "F" (match frame) to reveal the audio file in the source monitor with the "new" audio channels and with the in/out points already set.
6 - "." to overwrite the clip with the new one.
7 - The playhead will automatically move to the next cut, and then repeat "F", "." till you reach the end of your timeline.
for your second step, I don't see preferences anywhere!
Thank you very much I have figured it out!
