Hello guys, i met the same problem recording from an ATEM TV Studio with Media Express. Looks like the problem comes from the speed of the Hard Drive: it’s not fast enough to record HD Video without loosing frames, jumps and all that ugly stuff. So the audio and video was not in sync at all. I noticed this because, at the same time, i was recording the same show in SD, and this recording was perfectly in sync.
I adjusted the timing of the HD video recording with Final Cut Pro X, so that the sync was good in the beginning and the end… but still, the audio and video are out of sync in the middle of the recording: a big chaos.
I tested the speed of the Hard Drive with the Blackmagic Design Disk Speed Test, and it confirmed that.
So now i need to know what options i have to record in HD. Any sugestions?
Thanks!
Pablo.
