You may need to set this to 2, the number of tracks you want.
I am not seeing your issue here, this is a timeline with the 4ch Sony EX clip both before and after modifying the audio channels. I used the same settings as you.
Could you Dropbox a sample of your video clips.
On my machine your download file is 2 track stereo both in Premiere and MediaInfo
Showing my ignorance here. It's a merged clip in PPro - but the source file remains unchanged. In the previous tutorial lesson, it has user merge a .wav file with the .mov file.
Going beyond the call of duy here - but if you're inclined, could you merge the files in a project, and once you have the merged file - try to modify the audio channels per my original post?
I can confirm with a merged clip all 4 channels come over to the timeline.
This all got a bit convoluted. To clarify, after merging to create new clip, you modified the channels on the new clip and only selected two of the four available (mono), and then dragged the new clip (which presumably only has 2 channels now) into new seqauence and instead of just 2 all 4 came over?
Thank you for your patience and for your help.
Yes - something local to my system apparently. 2 days ago I was doing this same tutorial and it worked fine. Another note - it's intermittent, but often when I right-click and select modify-->Audio Channels, the window doesn't appear. If I try again, the window appears.
BTW - right before I tried your suggestion of changing it to "2" clips, I completely uninstalled PPro rebooted, and re-installed. However, it pulled down my settings from before. I wonder if I need to reset my preferences somehow.
Any news on this ?
