Will it be viewed directly from the site you are uploading to? Or is that just 'storage'?
If it is just a storage area, you could compress the file with WinZip, PKZIP, or another "zipper".
However, nobody could view it without first 'unzipping' it.
If it is for public viewing, such as YouTube, you could lower the resolution a tad, and save some MBs.
