I have some m2ts video that was recorded with 5.1 audio. In the Audio Preferences for Defaulttrack format it was set to 5.1. When I add the file to the timeline it put the video portion of the file on track 1 but the audio portion on track 4. There is a little 5.1 in the upper right corner of that track header for track 4.
I changed the Audio Preference to Stereo and started a new project. Now when I add the file it put three audio portion in the timeline on track 1, 2, and 3.
Can anyone elaborate what is happening? I think I understand the first part of the 5.1 going to the 5.1 track. But why would the stereo setting create three separate audio tracks instead of the 5.1 audio?
