Home Movies on CD

[airforce]

Hi,

I have a CD which contains old home movies - originally 8 mm which were copied to a VHS cassette ages ago - and I wonder if our wonderful Macs have some hidden methods (software ?) to enhance such movies.

Main problem is that some sections  are kinda dark and some scenes would need to be made brighter for better enjoyment/viewing.

Any suggestions for something which may alreay exist in my Mac (iMac G5 Power Mac) - or freeware or even shareware if need be.

Thanks
