Emulator with AVI capture and CPU throttling?

The title pretty much says it all. I’m looking for an emulator (with CPS-II support, of course) with both AVI caputer and CPU throttling/clock adjustment features. I’ve found a handful of emus with either one feature or the other, but not both. Any help appreciated.

Mame has an Overclock CPU option, hit Tilde and arrow through the options until you get to it. I’m not sure it works with all games, but I just tried it in Vampire Hunter and turning the percentage down did make it go slower. So any Mame with AVI recording like 90 or Plus Plus might work for you.
