I am new to digital video editing and have a question about capture cards. I am editing currently with Pinnacle Studio 8 deluxe and am capturing from Sony TRV-27 to an ATA133 7200 rpm HD via pinnacle firewire card. My system is Athlon XP 1900, 512MB Corsair PC2700 DDR, Radeon 7500, Windows XP. Will I get a boost in quality of video or improved rendering times if I get a dedicated video capture card? Any insight into the benefits of using a video capture card would be appreciated.
