I'm a teacher who who is trying to help solve a technical issues. We are using FCPX.
One of my student projects shot with the Scarlet. They shot 29.97 frame rate but at a 23.98 time base. They didn't know about this other setting and didn't know how to control it...
Their audio is 29.97 non-drop/48khz
Anyway, we had them transcode the footage to 29.97... but we can't get it to sync. And the thing is the sync drifts crazy fast, like within a few words.
I went in and did a sync with the original un-transcoded footage (23.98) and got the same weird sync... it drifts within words. My understanding that even 23.98 synced with 29.97 audio shouldn't drift that fast.
Any thoughts? Any ideas? Any experience with shooting in the Scarlet with 29.97 frame rate but at 23.98 time base?
