Question / Help How do I set video output resolution to sub-region?

[ZENiiTH]

My monitor's resolution is 1600x1200 @ 4:3 aspect ratio. I'm trying to capture a region of 755x650. When I do a file output of the capture, the video is locked at 1600x1200 instead of 755x650. How do I set the resolution of the video to that of the selected sub-region?

Go to Video settings and for Base resolution, slect Custom and set 755x650. Then the region should fit precisely in your scene.

Hey thanks! I have another question, since I see that you're a dev. Is there any plans to have OBS automatically set base resolution when selecting sub-regions? And then revert to original resolution after recording/streaming is complete?

No, this isn't really the way OBS is normally used. You usually want to keep the base resolution the same regardless of what you are doing with it. Switching scenes will likely introduce new sources that may be of different sizes, etc, but you cannot change the resolution of your video while the stream is active, so you use this base resolution to fit all your sources inside.

If you don't mind stopping in between, you could use profiles to store different sets of settings. You can set a different resolution per profile. However, this isn't really the way OBS is supposed to be used, because the same scenes will be used for all the profiles, and your sources that fit in one base resolution won't fit in another base resolution, etc.
