How do you remove left,right black bar?

In Youtube video I've seen people playing this game with no black bar



But when I play and record there is black bar
tried 3x for 1080p and the 4K resolution there is still black bar
I'm running 1080p borderless window
I would prefer to not have black bar in my video
Are they using video editing or they originally don't have black bar in the first place?

You can use Dolphin's graphics options to crop the image or stretch it to fill your screen.

Thanks I actually just capture both pic at full screen and I can see that the picture is stretched out.
I think I will prefer black bar rather than stretched picture (Even if it really hard to notice it)
