Hi, I'm new to the forum and I didn't know where to post this...
My team and I seem to be having an issue with syncing for our videos...
When the videos are on my mac computer the audio and visuals are in sync, when I upload it to our dropbox and when it's downloaded by our editors it is out of sync... Even though the Frame Rate is constant? Anyone have any idea what the issue might be?
To also give context, I don't think it's related but thought i'd mention.... Some clips seem to have a phasing issue, the original files were fine but after they were colour corrected and rendered out to be handed over to our editors the sound became distorted on certain mobile devices unless the audio is panned to the left or to the right and we have to duplicate the audio file and pan one side left, one side right and invert either one of those sides.
