I am having video lag on my recordings, both in preview and the actual file. I recently got a Vanco capture card and I run 2 monitors. Before I got the capture card I would record using my pc only and the footage never lagged but it was super pixelated during fast action moments (i.e. turning around fast in fps games). Nothing I tried fixed that and now I'm here with this problem of recording lagging or freezing on one frame. I'm hoping someone can help me. Log below.

The log is incomplete but there's no rendering or encoding lag. Have you tried with Kaspersky disabled?
Looks like Nvidia NR is in play but the app is not installed.
On the recording tab, uncheck re-scale output.
Encoding settings, set Tuning to HQ & Multipass to Single Pass or qres.
Sample-rate mismatch on the capture card

Thanks for your reply. I updated to the Nvidia app and deleted steel series sonar as it was causing the sample rate issues. I did everything else except turning off Kaspersky and OBS runs better now. I'll post details below.

You're going to need to test without Kaspersky. The new log shows your webcam running @ 44k. I also see that Logitech Plugin. Interesting that you mention Steel Series Sonar. That was set-up incorrectly but works perfectly when it is set-up correctly as I tested it myself.

I'm not sure if that plugin works with correctly with the current version of OBS. I had to go back to the July 2023 release before I saw any mention of OBS.

Maybe nothing, don't use it. I just don't update OBS until I've confirmed the plugins I use have been updated as well. Nothing in the Logi release notes in almost a year, except for fixing a crash with OBS.
How did it go with Kapersky paused, lag gone?

I had some lag in the preview window and in the actual recording. I'm also now having an issue where obs flickers and the preview window shows a black screen when I try to exit my game to do something on the second monitor while recording and it will not start showing the game again when I go back to playing. Here is my latest log. https://obsproject.com/logs/kg4w0GvzPYBvZ08t

Slight improvement but not enough to eliminate all of it. Do you have v-sync enabled? Might need to dial back the in game settings.
Your mic is loading up as a Global & Source input.
Sample-rate mis-match on the camera.
19:58:49.981: adding 320 milliseconds of audio buffering, total audio buffering is now 362 milliseconds (source: Logitech Web Cam)
19:58:55.763: warning: Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly
For your next test make sure v-sync is enabled & create a new Profile with just (1) Scene & (1) source. Want to make sure the current Profile isn't bugged.

Sorry I've been gone for a while. This log is a new profile with 1 scene and 1 source. The settings are auto configured for recording by obs.

The rendering lag got worse. The log is incomplete but the Vanco was used previously, might be the issue. Remove it from the mix & try a different source like a media source.
I don't know if this is what you meant. The video seemed smooth in the preview window. https://obsproject.com/logs/QlFVBl6BnMmXY3ie

The rendering lag is still there. Nvidia driver might be bad, could be a conflict or something else going on. OBS looks good & your hardware shouldn't be struggling with the settings in play.

I checked all the logs, incomplete. Post a complete log when you get a chance.
Run a recording session, close/re-open OBS & post the previous log.

Look-ahead, Psycho Visual Tuning and Multipass all use additional GPU. Look-ahead and Psycho Visual Tuning were disabled in the last recording but Multipass was not. Set Mutlipass to Single pass to disable it. Close any other programs that may be using your GPU such as web browsers.
Ok, I made the change to single pass. Hopefully this will show you the complete log. https://obsproject.com/logs/BBeH2CmGhNtZwZfV
Here is another one I just did after updating my Nvidia drivers. https://obsproject.com/logs/VMDFM4OtiV8HHWUU

So, there is nothing lagging, everything appears to be moving plenty fast enough but yet you still have rendering lag?
Just looked at the new log, the new driver produces basically the same results. Might be time for DDU.

With OBS closed, disconnect the capture device from the GPU, test with just the monitor.
When I look at the recordings in the file browser there is some random stuttering present. I went all the way through uploading to youtube and in the youtube video, any kind of motion made the video blurry and pixelated. I know youtube ruins everything to a degree. This log is without the capture card and just my 2 monitors. https://obsproject.com/logs/vtiQcGmhBxj5mfce
