Is there any free screencasting software?

I am searching for an OK and free screencasting app to finally start LP-ing.
The app doesn't have to record sound because I can do that sort of stuff with Audacity. Recently tried out "Copernicus", a screencasting app; I set the frame rate to 30, hoping for a good result, but it didn't turn out that well. In fact, it was horrible, the 8 second video I captured using this software turned out to have 2 frames per second.

If you happen to know of any good, free software for screencasting, please post some links.

Solution 1:

I don't do a lot of LPs, but the last time I did I used QuickTime Player.app (Quicktime Player X); you'll find it in /Applications. To record your screen, select File > New Screen Recording.

The results were pretty good; recording Minecraft 1.7.3 gameplay on an about a year and a half old MBP, but I have a lot of RAM, so that certainly helps.

Edit:

It's worth noting that QuickTime Player X does not support loopback sound; meaning that the only sound recorded will be from the microphone, or virtual sound device providing loopback sound.

This may or may not be a good thing, depending on what you are doing.

Jing

by TechSmith. There's a free version and a paid Pro version.

Solution 3:

Check out Screenr It allows to create great screencasts and share them online instantly.

It requires Java to be installed. For the first time you need to accept their Java Plugin to launch the Screen Recorder. I am using it for several small screencasts, because it just works.
