My current (aged) computer with 512 Mb of memory and a Centrino chip is struggling with what I'm asking of it. I'm converting all my old sports videos to digital and am trying to give chapters at appropriate points etc. For a 45 minute video, there is no problem. However, when I'm dealing with a full 2 hours worth of motor racing (~5Gb), it just gives up. What do I need to enable me to edit such large files? Would a new machine with a C2D with 2Gb of RAM do it? Or can I somehow use some of my 80Gb HDD to act as RAM? Thanks very much.
