Screencasting

Hi everyone,

I came back to this fantastic game after about 5 years.
I watched the other day some great youtube GP4 videos and searched the forum, for the software needed to make them.

I found a topic about Fraps, made the download and installed it but, a 10 second video I made was about 300000kb large.

I then searched the internet and found about 20 diferent software to record video from the screen.
Can anyone advise me on the better software for this?

Thank you and best regards
