It’s deceptive. And it stinks that it’s deceptive. Yes, some formats might PLAY fine. But if you use a lot of that footage in the timeline, you might lose sync. Export it…lose sync, or glitching will occur. This happens time and time and time again when people post here “Why did I lose sync?” “Why is the movie I exported not matching the cut? Seems to be showing random parts of the clips I used and not the parts I wanted.” “Why is my export out of sync?”
The first question we ask is, “Is the footage MP4, or H.264…some non-FCP codec?” And 99% of the time we get, “yes…it is!” And when I online shows that the editor has thrown in ANIMATION or MOTION JPEG-A or H.264 files, I always have issues.
FCP works best with FCP codecs.
