Hello everyone,
I have recently started using OBS to record footage of Video Games in window mode. Diablo 2 to be precise.
Sadly I had to notice that the sound was getting delayed throughout the entire video if the video has reached a specific length.
Here is a log of a video with the total length of 3:00:31 with audio-desync:
Here's a log from a perfectly fine short-test-video with the same settings (Length: 0:00:36)
Note: I have had perfectly fine recordings of lengths up to 2:19:07 without any audio desync.
I am not streaming, I use OBS to record videos.
Heres an album of my OBS Settings: http://imgur.com/a/PvkXm
Okay, lets get to my general questions:
Is it possible to record a window even though its in the background?
Are my settings okay? Can I configure something better? Did i configure something wrong? Can I be more efficient with bitrate or something?
Thanks in advance,
LaV

I've found R1CH's guide and tried it out. I will try recording a ~3,5h video later and see if its getting desynced

I have recorded a 3:15 5,2gb test-video with crf=20 and didnt experience any desync
