I've been trying to do extra filming the past week or so, but have run into this problem every single time I've filmed.
Below is a video example, but it's almost like the compression is making a sort of flickering thing.
The higher the screen brightness, the worse it looks, but it's still present.
No amount of settings adjustment can seem to fix it.

Uploading to Youtube made it slightly worse, which leads me to lean towards a compression problem of some sort. However, it's also present no matter the frame resolution.

Any ideas?

Also, yes, I know the environment is about the opposite of ideal, but I've got a small apartment and I work with what I can. Better film like this than not at all.
