My normal process:

Record Audio & Video in vMix using the following settings:

UserPostedImage


I also record the audio straight off my mixer because it VERY clean. I then bring the vMix recording into Adobe Premiere Pro and the mixer audio recording. This has worked every time, until now. Now, I can sync the mixer recording audio to the start of the video, but in just a few seconds it starts to get off and gets much worse over time. The only change I made was upgrading from vMix13 to vMix14.


Any ideas?

Hi,

I noticed you are recording to MPG instead of TS.
Some video editing programs do not handle the timing in MPG well leading to the problem you are describing.

To confirm if this is the case, play back the MPG in vMix or VLC and see if the audio is in sync.

If it isn't please email us the recording log file for further analysis.

Regards,

Martin

Pretty that is not the issue as I have always recorded to MPG. Also, the audio/video recorded by vMix is in sync when I bring it into Adobe Premiere. It's the audio I recorded straight from the mixer that doesn't sync with the video.

So I went back to the previous week's show where I used vMix v13. I loaded the MPG vMix recorded into Adobe Preimere, then brought in the audio recorded off the mixer and had no problem syncing it to the video. This should eliminate Adobe Premiere as the issue.

I guess I could use the audio recorded from vMix, but I just love using the audio recorded from the mixer. Not only is it super clean, I also have me on one channel and the guest/co-host on the other.

As for playing the vMix recoded video back in vMix, that worked fine and everything is in sync. My guess is it's something to do with the variable frame rate recording in vMix and for someone reason it's different in v14.

@ jpeg2RAW

Have you checked all the settings?
I've seen where an update to a new version of vMix resets to default settings for things that you may have adjusted in the previous version.
