It looks like I'm crouching but I'm not...How can I fix this? It goes faster than this, but when I'm recording it slows down.

From Metamorph's FAQ:

Q: My screen goes up and down. How to fix?
A: Most likely you installed MorePlayerModels mod alongside Metamorph. To fix that, either go to Mod Options > Metamorph > General and enable Disable POV option, or disable POV option in MPM's config and restart the game.
