I got a new camera recently and tested it out last night at a concert.

I took LOADS of video and it's brilliant except for the huge file sizes.  I had all the settings set to full and the video has come out well, but it's just too big.

700mb for 10mins

What I wanna know is if there's an easy way to reduce the filesize for several avis, whilst maintaining the format....a piece of free software or something.

I'm quite happy to play around with settings for different levels of quality to get a balance between file size and quality.....but I don't know what software to try

Any suggestions?
