I'm trying to edit video taken from iPhone6s in HD1080 at 60 fps (.MOV file), but it is dropping A LOT of frames playing from the timeline. I've tried with and without GPU video turned on, and no difference. I've tried the project at 60 fps, and the project at 30 fps with resample disabled, and no difference.
The same file plays with no dropped frames in Pinnacle Studio 19 and Windows movie player.
Is Vegas using the wrong CODEC?
