It's ticking at about 400 times a minute, which is half your warm idle speed of 800rpm, so it'll be the top end. Either a sticking valve or some oil starvation to part of the valvetrain. The way it suddenly completely goes away might indicate it's lack of oil.

 

edit - odd that it doesn't do it on cold start though.
