I could need help, even if I record with Obs e.g. Minecraft and then I want to play the video, only the sound is displayed, not the gameplay.
Upload a few screenshots of your OBS settings
I could like to do tomorrow morning.
Yes, screenshots of Video, Output (Capture), and the top of Advanced would be helpful.
For "Output", please set "Output mode" to "extended".
which CPU and which graphics card would also be helpful.
Which source you record with would also be interesting.
So either "screen recording", "window recording" or "game recording"?
Tried all 3, but the same problem?
Do you see the gameplay in the preview window in OBS, or is that black or something like that?
If you can see everything normally, have you ever tried to play the recording with another player? In theory, this could also be due to it, without OBS being to blame.
