video screen recorder

hello everyone
I need to find a "screen/video recorder" for my mac
so I can make gifs in photoshop
in my pc I used camstudio which was a good logiciel but it does not exist for mac so please if someone could tell me what I can use that would be great
thanks

There are several different screen recorders, if you just need simple recording, you can use Quicktime.

Otherwise you can use:
- iShowU
- Screen flow

thank you =)
