Audio Video Sync on HD recording

Whe I record a show to disk, the audio and video are either far out of sync, are they start in sync, and within a few seconds they start to drift out of sync. I have tried taking the recording and detaching the audio, and then speeding or slowing down the speed of the video to match the beginning and end of the audio, but then the middle is off.

Any ideas?

iMac 27 inch, 32GB, 4GB GeForce GTX 780, Logitech C920 camera, RE20 mic through a Shure audio interface

Here is a sample video

I just tried doing a test recording with the C920 and using the audio from the camera. It still loses it’s sync.

It should also be noted that when I record with Quicktime Player or with Screenflow, I do not see this same loss of sync

Which version of mimoLive are you using?

Version 2.9.2 (23125)

But this has been happening for a while, with a number of versions

You might give 2.9.3 a try.

Thanks. I actually seem to have been having a HD issue. I ended up fixing the hard drive, and wiping the computer, so it was fresh, and the issues went away.
