When trying to use a game capture, whole game does not cover black background screen

Basically, you know the black screen you are greeted with when opening OBS For the first time? i'm trying to get OBS To only get my minecraft game to record, and not my background desktop and i found out how to do that, but when i put on the scene for the specific window minecraft, it doesn't cover the whole capture screen, rather just leaves a black bar at the bottom that shows it does not cover the entire thing of what it can record if it is not in full screen, and i am scared of it suddenly showing my desktop or something like that or just a black screen if i alt+tab anywhere else just because i want to get rid of the black bar. is there any way to make the windowed and non-fullscreen Minecraft appear to be fullscreen on OBS? never had this issue in the past either.

The black space exists, because the aspect ratio of a windowed Minecraft is different to the aspect ratio of the canvas size of OBS. The space where the Windows taskbar is visible is left out, so it remains black. To make Minecraft also cover this area in the video, you need to run Minecraft fullscreen. If you don't do that, Minecraft simply renders no image data at that space, so OBS has no image info to capture at that place, so a black space appears at that place in the video.
