First time trying to record; got audio, but not video

[bhakti-rider]

I've just installed OBS, and I'm trying to make a recording. I'd stream to youtube, but my connection speed is too slow. I found my way through the menus and steps, and have made a couple recordings (from Microsoft Flight Simulator), but when I play them, I hear the audio but the screen is black. I've tried searching the forum, but didn't have any success for my specific issue. Any help would be highly appreciated.

I see about including a log file. I don't see anywhere to put it; I pasted it into Tags. I hope that's the right thing to do.

1. Run OBS as admin.
2. Not video related but at least one of your audio devices has a sample rate that doesn't match the rest. This can result in audio drift over time or sound distortion. Check your audio devices in Windows settings (both Playback and Recording) and ensure the Default Format (under Advanced) is consistent. 48000 Hz is recommended.
OBS Sample Rate: 48000 Hz
Speakers (Sound Blaster Z): 48000 Hz
Microphone (2- Maono Falcon Basic Mic): 44100 Hz

It looks like you only have 1 GPU but also try forcing OBS to High Performance mode. See:

Laptop? Black screen when capturing? Read here first.

Depending on your Windows version and what sources you wish to use, you may need to set OBS to run on a specific GPU. Not sure which Windows version you have? Press Windows+R and run "winver". For Windows 10 1909 or newer: Open Settings and search for "Graphics Settings". Select "Classic App"...
