Question / Help Zoom Window Capture delay

[ShailyRae]

Hi folks, I've had a look through the forums but don't see any solutions for the particular issue I'm having, so hoping someone can help! I'm really new to recording and such, still learning my way around it all.

I'm using Zoom for video calls, and trying to use OBS to record it. I've already got IShowU installed and set up for desktop audio. Everything is up to date (only started using this in the last two days). I have two sources set up, one for my webcam, and a window capture for the Zoom meeting window. Everything seems to be coming through for recording just fine - except the Zoom meeting video, which lags about 1 second behind everything else. My audio and video match up fine, and the desktop audio is coming through perfectly, just the video call doesn't seem to be able to keep up.

Is there anything I can do about this video lag? It doesn't seem to happen if I do Display Capture, but I'm concerned about opening a different window mid-recording by accident.

Keen to know the answer to this too, any help appreciated.
Also concerned about doing display capture without having enough space on the screen to run other things.

Any word on this? I'm running a live stream via restream to YT and FB. 1 Studio Camera and Zoom for a remote host. Studio cam has zero lag in preview and while streaming. Zoom is coming up fine and in time on the zoom window, but when I bring it into OBS it lags horribly. All my output rates are set accordingly to my Upload speed. Thanks in advance.

I have the same problem and have not found a solution yet.

As soon as I switch from window recording to screen recording, there is no perceptible delay between image and sound. However, I would like to continue using window recording and not record the entire screen.

Thank you very much.

Howdy! I understand the frustration for you guys - as I have had similar issues when using OBS and Zoom.

The solution that worked for me was to delay my personal recordings to match up with the zoom recording. I know it might seem a little bit over-engineered, but it is possible and works fine for me.

I would set a microphone delay (for your personal microphone in OBS) to be 1000ms. That would then line up your voice with the rest of the audio coming from the zoom call within the recording. You can then add a render delay (and buffering could help too) in order to sync your video to the audio you just delayed.

This would make it so that the OBS recordings will be 1 second behind what is actually happening live - however, unless you are actively monitoring your OBS mix and stream/recording, this shouldn't be an issue. As long as it is synced in OBS, the recording/stream will be synced and the audience won't notice a difference.

Not sure if this answers your question but hopefully this helps.
Please let me know if this works or if you have any questions.
