How do i fix my recording quality

Well, from what I've read, a lot of Fortnite players are running the game in stretched 4:3, which makes enemies bigger and easier to hit. If this is what you're doing, despite the game filling the screen, it's still running at 4:3 aspect ratio when you capture it, so the videos will look 4:3 instead of 16:9.

The only way to solve it is convert the 4:3 video to 16:9 before you upload it to YouTube, or play in 16:9 instead.
 


I dont play in stretched res, i just use my monitors default 4:3 1280x1024 res so if u could tell me how to convert 4:3 to 16:9 it would be appreciated :)
