Cortex not properly reading timecode from some GoPro footage

Yep, that’s what we currently fall back on when we can’t read any TC in the metadata. That will be changing in the future, but doesn’t answer the question at hand:

Good question. I’m kind of surprised this is the case. I think we need to get our hands on one of those files. If you can provide an example and also let us know what timecode those other apps are reading, I’m sure @amy and @peter can help take a closer look.

Are these .mov or .mp4 files or something else? And which version are you currently running?
