Avid media composer 8.5 GoPro & C300 sync
Hey guys & girls.
I’ve got a lot of GoPro and C300 material that I need to sync up.
My normal workflow, is to link, consolidate (relink), and then manually sync all the clips, used Plural eyes before but that dosen’t seem to work with 8.5.
A side note, the gopros seems to get off sync randomly after a while, is that because of the camera or? – At the beginning it is synced perfekly but after maybe 2-5 minuts its out of sync.
Is there any chance that there is an easier way to do this?

What frame rate are the cameras shooting at?
-
25 fps

The latest version of PluralEyes no longer support AMA, so it is not so much an MC version issue than it is a PluralEyes dropping support.
Sync that drifts indicates either picture or audio are at slightly different rates – either fps for picture or sample rate for audio. What is the nature of the drift? One frame every _____ seconds? Picture ahead of audio or audio ahead of picture?

It might be the go pros audio?
Next time I’ll check the One frame every ___ seconds.
Its the go pros sound and picture one frame ahead of the c300 and external sound. -
The GoPro sound may be the culprit. When you AMA link to the GoPro media, go to Source Settings, Playback TAB and see what it thinks the source might be. In that tab, there is a menu that allows you to select source rate, or project rate. Even if the same, select Project to see if that changes anything.

I can’t change the frame rate, it won’t let me. 🙁
-
Could it maybe be that the go pro is interlaced and c300 progressive?
-
That could be – using something like MediaInfo on the GoPro clips would give us insight into frame rate, sample rate , codecs, p or i, etc.
