Actually, Jing doesn't work for me. It has a 5 minute video time limit, and it saves files as .SWF. Is there any working screen recording app for the Mac?
You can figure out the freeware/shareware/payware side of things. I will say that if it's a program you'll be using a lot, and you expect to have some nice editing options, then it looks like you'll have to pay for some program.
