I am trying to find a better way to video record my kids Basketball games and share with other families. I was thinking that if I had two cameras (one recording each side of the court) than I could take those two videos put them side by side on my computer and then move the capture window back and forth across the screen between each video I would have ONE master video of the whole game.

Anyone have any advice on doing this, I am so tired of sitting behind a camera going back and forth.

The feature that places different scenes on single canvas/window (for easier selection) named "Multiview". In OBS you can find it under the main menu View > Multiview (Fullscreen) or View > Multiview (Windowed).

Some guides has more info about the feature:
In short, you placing cameras at different scenes, enabling Multiview for these scenes, and clicking inside Multiview window - clicked mini-preview goes to output (goes online or recorded depending what you doing in OBS). Usually, it is easier (bigger mini-previews) to use standalone monitor for Multiview feature, aka "Fullscreen", while OBS running on another display.

If you using only 2 scenes (way less then 8, which is standard for Multiview), then right-click over the desirable scene and select Windowed Projector (Scene). In opened window - right-click and select option Always on Top. The window will be drawn over any other window on your PC, so make it only after all other settings are done. Repeat this for other scene. Now you have small live previews of each of your scenes on your monitor. Don't forget to assigned hotkey per each scene in OBS Settings > Hotkeys to switch between these scenes with ease. Hotkey itself is named Switch to scene.

Nice idea...until you find that the seam between the two cameras is obvious and really hard to fix. The distortion that is required to "stitch" that together seamlessly is surprisingly complicated, especially if you're capturing a 3D scene. We don't notice the lens distortion at the edges when we're looking at the center, but when you put those edges together, the mismatch becomes glaringly obvious!

It's orders of magnitude simpler if you're just putting projectors side-by-side on a flat wall. Those lenses are designed to not distort (as much) in the first place, so it's mostly a matter of careful alignment and then keeping that alignment. (still easier said than done) A software fade-to-black on their edges doesn't hurt either, to make a cross-fade instead of a hard cut, but now you have some dedicated smarts to do that and generate the required video signal to send to each one.

Back to the cameras, I think you're better off either wagging the one camera like you've been doing, or switching completely from one camera to another like Suslik says. Don't try to combine cameras on a single view.
