Screencapping question..

First up! HAPPIEST OF BIRTHDAYS to the gorgeous and supremely talented maichan808. Oh man! My LJ life would just not be the same without you hun!!! *snuggles you tight* I wish I had got my act together to make a wee vid for ya sweetie! You'll just have to accept my warmest of wishes and snuggles.

And I got TWO, count 'em, 2!, Christmas cards from her! *dances and feels special*


Now the question....

Could some kind soul please let me know if I need a specific program to make screen caps *feels ridiculously naive*. I started making them with my VLC player, but that's proving to be a pain in the neck. I know I can screen capture in my vidding program, but that seem like a long way around. So, if there a good program to use?

Thanks if someone can assist this newbie. Oh and I use a Mac.
