ATEM TVS 3.5: H.264 Audio out of sync

PostMon Feb 11, 2013 12:44 pm

Hi,

I installed the latest 3.5 software/firmware on a new ATEM Television Studio.
I recorded a test of 5 hours H.264 recording.
Already after a few minutes the audio/video looses sync.
I probably need to roll back to an earlier version. Anyone who can advise me which software version I should use instead?

Somewhere I've read that the issue is caused by the desktop video driver or the version of media express. Don't know if I've read this here or on atemuser.com. I think the ATEM software updates these, too.

I mailed Blackmagic support. Turned out to be the Desktop Video driver. Downgrade or wait for update and it will be fixed :)
