MOV/MP4 Compatibility
I am working with mp4 files and an MOV file. When I loaded the MOV file into a "sequence," the audio and video tracks un-synced. There was nothing wrong before.
It's possible this was simple human error, and perhaps I unsynced them accidentally. When I loaded the MOV file into the sequence, I saw the following message (see below). I can't remember what I clicked. I have also re-scaled the video.
How do I ensure that the MOV file and the MP4 file can co-exist in the same sequence, and the sound/video all look fine and synced when I go to export?
