Question / Help 2 hrs trying to select a region to record

[BOBC]

Hi,
I simply want to draw out an area I want to record on the monitor, hit start then later stop and see just that as the entire video.
So if I draw an area 300pixels wide by 250 tall the video will be those dimensions !
I have seen about alt drag the handles, but when I launch OBS I see the obs interface, and a smaller one add infinitum, I cant see the screen i want to record. If I then undo the full screen size of obs and resize the obs floating window I still see the obs screen , confusing now just what its recording.
Why cant we just be able to have OBS minimised and not visible, hit a hotkey for draw region, draw out the region we want to record using mouse, then hit start hotkey and stop and when video is played back, all we see is just what was in the region we drew.
Jing does that, techsmith does that, its so user basic intuitive.
I have altered the red line area yet final video is still capturing an area below the region I want, and has large black margins.
I see mention of window option and sub region but cannot find that in OBS 23.1.0 as all this advice is for an old version. If there is a video anywhere showing how what I want is done, please provide a link to it, one chap says its easy use alt, yet he is seeing the video he is capturing playing, I cant get my version of OBS to act like that, having chosen video, I dont have a video playing, or a game, I have a CAD program open and just wish to capture the 3D perspective view of the interface, not the menus etc.

We need my draw region method above, 2hrs getting nowhere, mentally exhausted yet this should be so easy to do.

I have lost a lot of time to find this function - I have not found it myself and I do not see it in tutorials either.
I just do not believe that this may not be in this program and I am also asking for a response and help in this matter.

You achieve this by adding a display capture for the desired monitor. The whole monitor is now visible in the preview. Now you have the handles at the border of that source in the preview. You may have to click on the preview once to see them. Now press and hold ALT and drag the handles to crop to the rectangle you want to extract.

Thank you very much for your answer.
This, of course, would be very simple and would solve the whole matter.
The problem is that in many tutorials show how to record a desktop showing such a picture and not explaining how to get rid of these multi windows in the view.
They show how it was completely normal, and this is completely illogical.
How do I enable normal desktop recording (not windows, etc.) so that I have in view only what I have open on my computer, not the multi windows?

The mirrors will always appear if you capture the same desktop OBS is running on. You have to make it so that OBS doesn't appear on that desktop. That is:
Run OBS on a second monitor and capture the first monitor. Or vice versa.
Or simply minimize OBS (this way you are not able to manipulate the preview, though).
But usually, you window-capture or game-capture the thing you want to capture, so you don't need to crop in the first place. In this case, the thing you want to capture just appears in the preview without the need to crop anything.

Thank you very much, and now I have to find time to play with it :)
