Long Multicorder recordings end up out of sync. We are using HDMI input from Sony Cameras as backup recordings for a podcast.

Audio and Video are coming in synced. If I perform a short recording, audio and video are synced. Problem occurs with long recordings(in excess of 30 minutues), the video ends up 10-15 frames ahead of the audio in the final recording. It is not drifting, the entire file is out of sync.

We are recording in mp4 format using the standard settings, using hardware encoder. Our computer setup exceeds the requirements and we are recording to a seperate internal SSD. We always record 2 cameras and they both end up out of sync.
