Lags on recorded video (not on the content I am recording)

Hello everyone, many of my videos recorded in OBS have been experiencing lags lately. Sometimes the video was recorded without lags; sometimes half of the video was smooth, and the other half was not. I set a higher priority (higher than normal), and it got a little better, but the problem didn't disappear.

Please help me solve this problem!

I've attached the Log File of the session where there were lags in the recorded video.

You seem to record to a H: drive. In case this is an external drive connected with USB, switch to an internal drive for recording. External drives are usually not write cached, and this might lead to issues with OBS while writing long continuous data streams.
Your log contains a short 10 second recording with no issues. Settings seem fine, even conservative (only 30 fps). No lost frames logged. Either this is the wrong logfile, or there are no issues with OBS. Try a different media player, for example vlc. The Windows integrated media playback often doesn't work well.

H: drive is HDD. I'll already tried VLC and I can still see the lags.
Just now I've recorded few videos and in the videos named "2024-04-08 16-06-23", "2024-04-08 16-16-43" and "2024-04-08 16-18-02" there was frame drops.

HAGS is enabled in the last log, that should be disabled. There are also a couple of Scenes that have multiple Game/Window Captures, only 1 per to avoid interference. Your recordings will always stutter with the monitor @ 75HZ, run it @ 60 when using OBS.

Audio lagging here:
13:42:32.151: Max audio buffering reached!
13:42:32.151: adding 917 milliseconds of audio buffering, total audio buffering is now 960 milliseconds (source: Устройство воспроизведения)

Thank you for the answer! So I need to change the monitor refresh rate to 60 when using OBS? I'm recording a video on the scene where I've left only a screen capture. Will the other scenes with other captures affect the recording?

See how it goes. Hopefully that audio lag clears up with HAGS disabled. If you're still seeing it happen, I think it may be from the Nvidia NR filters. They're set but not being used as the app is not installed.

Well... The problem is 95% gone. But for some reason, sometimes the video can still lag at some points, which is very rare, but it happens. I'm attaching a log file in which a fps drop occurred during the recording of one of the videos (I think the first one).

The log is incomplete

Your audio is still lagging, Nvidia NR is still in play & not installed. Remove the NR filter, see if it improves. If not, test with the source removed. It may be the audio driver if it still continues.

Thank you for the answer!
1. I don't know why it says that I'm using Nvidia NR, because I'm using Speex noise suppress.
2. I'm recording video in orther scene that don't have microphone input, it records only system/game sound
I'll try to reinstall or do something with audio driver

These are not needed & can be disabled (Windows).
13:12:20.962: Game Bar: On
13:12:20.962: Game DVR: On

If you're going to update the audio driver, get it from the support page for your mobo.

Thinking out loud. The Audio Source is in both Scenes. Was it added to the second Scene as "Create New" or "Add Existing"? Looks like Create New was used when it should have been "Add Existing"
