i would suggest getting a macbook pro IMHO. With the integrated graphics in the MB, you won't be happy . especially when editing video. Video is my job, its how I get paid, and if I don't have a computer that is completely up to the task of editing, I'm not running as efficient as I could be.
If your an amature videographer, then I'm sure the macbook will do fine...but if you are doing this for more than personal gain, I would suggest getting the MBP with 2GB of ram and the non-integrated graphics.
