Does this ring a bell to anyone? It's my first time using DVR but I hadn't expected something like this. I'm using DVR 17.1.1 build 9 (downloaded today) on macOS Catalina (with an Intel Mac). I simply chose "File > Quick Export..." and selected the H.264 option.
I was able to confirm that the audio is indeed in reverse by running ffmpeg over the exported file (export.mov) to un-reverse the audio like so:
Viewing that post-processed file (export_reversed.mp4), the audio suddenly made sense again, but the audio stream nonetheless started a bit late so would need resyncing, which is a pain.
Has anyone encountered this? Is there any way I can export my data correctly? I've sunk a whole day of work into this now.

- Code: Select all
ffmpeg -i export.mov -c:v copy -af areverse export_reversed.mp4
