I honestly prefer DxTory if you know your way around the settings. :3
Much smaller filesize than fraps.

fraps or xsplit or dxtory

Personally I use Fraps to record games with a high FPS and then Camtasia to record games where there's not much fast paced FPS stuff going on and any desktop stuff. At the moment Camtasia is my most used as I've been playing a lot of indie games with small desktop displays

Search around the internet and download a few that you like the look of. It won't be an easy job..

Fraps is the most popular as far as I know, but check out Bandicam, dxtory and Camstasia. So far, I've had the best luck with Bandicam and Camtasia.

But remember, Fraps will ruin your fps more than most other recording programs.

Good luck with your recording!

I use Bandicam. It gives you ten minutes with the free edition, plus you can target a small area on the screen for filming, making it handy for flash game filming.

Fraps is the best, u can compress you files with sonyvegas Or Microsoft Expression

You can also use OBS' local recording option. Great quality with low disk usage.

Depends on your specs. If you have a lot of HDD and a very decent PC, go with Fraps. if not, Bandicam is a really good alternative and it's what I'm using right now.
