Question / Help Video ever so slightly after audio

Hi!

So I have been using OBS at work for a while, and yesterday I saw it more pronounced than before - it might have been this way for a while. But the audio gets out, ever so slightly, before the video. I did not really notice it before we zoomed in on his face around an hour in to the video so fast forward to that point.

The Video:

So how do I deal with that?

use mic offset and increase it by maybe 400ms, you could also raise your scene buffering to 1000ms which might help as well. but it seems to be desync'd at the same rate from the beginning to the end of the video.

Also, your keyframes should be 50 for for 25fps, which is key frame interval of 2. if that works for you, you can remove the custom x264 setting of "keyint=48"
 
A slightly less than short after reply, but having the mic offset at 400ms did the trick! I also changed the keyframe interval, which I sadly tend to forget after each time we change the stream material - since it is so seldom we do so. And since we are streaming to the youtubes, we have to set it spesifically - if I remember correctly.

Anywho, thanks for the feedback! :D

youtube just needs keyframes, but its best to align it with the fps. just set keyframe interval to 2 and take out the custom x264 setting. setting keyframes to 2 says "every 2 seconds, send me a key frame" which if 25 fps will set the keyframes to 50, and dynamically if your fps goes up to 30, then sets the keyframes to 60.
