So I have these hour long work out videos that a friend gave me from an old rugby coach. As such I want to make a video with them to give to a friend of mine. However, the file size for each video is really big. They are also .mp4 files if that helps. I am not awesome with computers beyond the basics. Is there any way for me to put these all together in a compressed manner that I could put onto 2-4 dvds? Thanks for the help.
