[CLOSED] Video Quality Terrible When Uploaded, Please Help

[AlexTries]

My video looks great after I record it, however when I upload it to youtube the video becomes blurry and pixelated. How can I fix this? This has been driving me crazy for hours. I will include a link to the unlisted video below to show what I mean

I uploaded a new version of it in 4K and it seemed to have improved it a little bit to being acceptable. Still not the results I wanted haha. This thread can be closed
