I have a peculiar situation wherein I create an MP4 to upload to Vimeo. When someone tries to watch the video on Vimeo using their cell phone, the video plays fine, but no audio. I have traced the problem to my original AVCHD file. It has a stereo track, (actually a two track mono) but the tracks are out of phase. When played back on a stereo device, no problem. When played back on a mono device, no sound. I know I could invert one of the tracks in an audio editor, but that would be time consuming as the video ofter runs almost 2 hours. My question is, when I produce the mp4 in PowerDirector 13, is there anyway I can solve the phase cancellation problem?
Strange, the audio is out of phase.
My suggestion for your case, open the audio in WaveEditor, copy a channel to the other, so will the two identical channels.
