So how do I make a GIF of this?

[p4r4d15v0g3l]

Can someone make a GIF of it getting blown to smithereens?
I imagined a shot of the cube over the whole first pic.
Then a rocket should come out of nothing and erase it entirely.

I'm really terrible with the camera so it wouldn't turn out as it should be.

Alternatively, is there an easy way to do that?
Maybe a way to hide the HUD(didn't find an option under controls)?

Thanks for any responses,
