Sorry wyziwig, Im a beginner and I know nothing about what you need to know in order to help me.
Hope this helps...
I have a Samsung mini DV and I am capturing the video via firewire to my pc using Premiere. Since my pc didnt come with a firewire port, I had to buy a firewire card, and I have been using that. Since I'm using the video card that came with my Dell, I doubt its that great of quality.
I guess what I want to know is if a good video card, such as Eds ATI, means better quality as opposed to capturing video with an average card.
