Making A Montage/Capture Card Help

Hey guys, I was wondering if I could get some help from the community on making a montage. I have a ton of clips that I would like to make into a montage and I want it to be in as high of quality possible, but also a reasonable price. I was wondering if anyone had any recommendations on a capture card or some other device that is the best way to get my clips from theater to the PC. thanks for the help!
