I used playclaw3....I don't like 4 as much as it crashes my killing floor. with it you can also use an overlay for your FPS, CPU load/temp and GPU load/temp. you can also turn them off as well. It records pretty good quality, minimal to no FPS drop, and you can get a trial version that has yet to expire for me that does everything you really need. I think in the full version you can change the video output type, but I have seen no need to. It throws a floating watermark on the videos for the free one, so if you don't want that, try to find a cracked copy or just pay for it.
