Out of Synch Render on Clients Computer SVP 11

LoanGenie wrote on 3/28/2012, 6:10 PM
After I render the job and on my computer, playback is perfect. But on the Clients computer (the one that matters) the audio/video get out of synch pretty quickly (minute 1). I notice that my old laptop playback is 1/2 second off immediately and gets worse.

How do I get consistent final projects? Are there settings I'm doing incorrectly?
Is my computer a problem?
Any Help is most grateful.

Are you playing these MP4 videos with the Quicktime player? It's notorious for playing out of sync (and other problems as well.)

Why are you converting from a compressed format to a highly compressed format? You are starting with compromised video quality. I wouldn't trust any consumer "converter" program. just drop the original MPEG2 file on the timeline. You should edit in the original resolution and only downscale when you encode ("Render As") the final output.

I am no audio expert, but I think your problem is that your original audio bitrate is different from the project and "Render As" settings.
