[OFF Topic] How to rip video?

Hello! I have made a small video of my golf so as a reminder etc. I recorded it with a normal video camere. About the TV input on my TV card I can watch the video on my PC. Only how do I rip it now? If I do this quite normal as AVI with the program what was there then is a minute about 700MB big. Probably somehow with MPG or something. Can one help me there? Thanks.
