Looking for camtasia alternative for Linux

Does anyone know of a really good screen recorder on linux that has quality that is comparable to camtasia?

 

One of these should fill your need:

Cheese does it as well and with some effects.

 

Thanks fellas.

Update: I'm now using recordmydesktop. I would like to warn KDE users it took a little horsing around to get the audio to work. Other than that minor hiccup it's good.

 

What did you solve yourself that I might run into as well?

 

Don't know about KDE, but with Ubuntu Gnome: Open gtk-recordMyDesktop>Advanced>Sound. Then Channels=2
Frequency=44100 and importantly, Device=default (not DEFAULT). For Microphone Channels=1 Frequency=22050. When using Microphone (I have USB Microphone) click on speaker icon in panel >Sound Preferences check Input Microphone detected (AK5370) and ensure that input volume amplification is not muted. gtk-recordMyDesktop is a great application.

 

I like RecordMyDesktop the best but I can't get audio to work with OSS (I ditched ALSA a while back).

 

try pulse.

 

For KDE you install recorditnow instead of gtk-recordmydesktop, it will then detect the sound interface on its own.
