Alright. So my camcorder is pretty entry level, consumer hd camera, the canon vixia hg20.I've owned my computer for three years and it runs windows vista. When I upload video, it plays fine while in a standalone player a little glitchy sometimes, but when I attempt to edit footage in any form of editing software, it glitchs up and often freezes the whole computer. The camera shoots I think 1080p. Is there anything I can do to make it run smoothly?
