Can you help me? On step three of uploading videos, the screen goes blank. Can u help me fix it?

I'm cameronrules36, I started off reviewing random games, I didn't do very well, but now I'm obsessed with writing really long and in-depth reviews with my opinions of the games i won. I would also like to recommend eberderelict, his reviews are very good, I enjoy reading his reviews and writing my own of the games I've played.

Here's a link to my written reviews:

Here are some links to the reviews I think I have done the best:
