Modify audio channel is done in the Project Window.
Normally you can do this per clip also. In the screencapture I made you see it working in the beginning, but after moving my sequence to the "edits project" the function is suddenly greyed out.
Yes you can do only certain things on the clip in the timeline.
Some features need to be set before dropping it in the timeline.
But I never have this when not working inside Productions. It's quite a standard thing to have, the ability to change the channel of a clip inside the timeline. I record two microphones, one on the left channel and one on the right channel, so I need to change inside a clip several times the channel when I have a dialogue for example. I'v already done this in Adobe Premiere for hundreds of movies, so I don't understand why it is suddenly not working. And as you can see in the screen capture, when I first create the sequence you can see that the function is available, but after moving the sequence to another bin the function is suddenly greyed out. So I don't understand the logic of this.
Did you resolve this, out of interest?
I've just come back to Productions, having worked with the same setup just a few months ago, and I'm experiencing this exact problem.
I didnt resolve it yet, but what I read in a Facebook post was that it is a known bug in the latest release. They already resolved it in the most recent beta-version aparently . Just wait for the next release, or roll back to the previous Premiere version. (or get the beta).
Just upgraded to version 23.0.0 and still this problem 😞
The only workaround is to copy the sequence in to the same project as where the source material is coming from. But then the whole idea of using productions makes no sense anymore especially if you are using material from different projects.
not copy, but move i mean
