    Audio Channels in Timeline Keep Changing?

    LeBeauStudio Level 1

      I have some audio tracks, on those tracks I inserted a .wav file that has 4 channels.  I only need 2 channels. ( 1 and 2 )  I unlinked the audio and I am just using channels 1 and 2.


      Channel 2 on the timeline keeps defaulting to Channel 1 - I change it and then next time I open the p[roject the audio on channel 2 goes back to channel 1.


      I hope this makes sense.

      This picture below is what it changes to and I have to reset the channel.

          --> source is 4 channel WAV


          --> Audio mapping:


          1. source channel 2 -->  mono track channel 1


          Have you made a copy of the WAV in the bin to set the second audio mapping assignment?


          2. source channel 1 --> mono track channel 1


          So it would make sense that the audio is pointing to source channel 1 because that was the last assignment you made?


          I use the channel assigment a lot for 5.1 tracks it is working fine for me.


          --> Can you describe a bit more what doesn't works like expected?

            Thanks for your help.  I haven't made a copy of the WAV.


            In the timeline, the 4 channels are linked together. Ch1 is a LAV Mic, Ch. 2 is a Seperate LAV mic, Ch. 4 is a boom mic and there is nothing on channel 3.


            So I unlinked the WAV file in the timeline and removed the audio channels that I did not need in the timeline.


            Then I moved the 2 LAV mics to Audio Channels 1 and 2 on the timeline.


            I think that is when I noticed that both Channels were the same... not sure - I have moved stuff around so many times.


            So in the timeline, I would "right mouse click" on the audio track in the timeline and modify the audio clip by clicking on audio channels.


            As a work around, I modified the LAV audio clips in the timeline to where they needed to be and did an audio mixdown of just my LAV mics.  Brought that file back into the timeline and muted the others that kept changing on me.


            Does that help?  Thanks again!

              Ahh - now I understand ;-)


              so much channel tracks switches...


              Premiere forgets what source channel to use and switches back from source channel 2 to source channel 1 after the project is reopened.


              I'll do some test's here and see if I get the same problem...

                Good luck,

                  I also have this problem. The workaround seems to be to use the Audio Effect "Fill Left" rather than the Channel Assignment method - which just reverts when the project is saved and reloaded. I still don't know why this happens - I think it's a bug.
