500 Lines of Resolution. Computer Get as powerful a system as possible. P-II 350 or higher. Due to the complex mathematical nature of compression codecs, the faster your CPU is the faster your projects will render. Most major software editing packages are planning to support the Pentium III's new SSE instructions, so if you can afford a P-III it could be a wise investment.
Video editing is very data-intensive and requires constant data updates.
The more RAM, the less your hard drive has to be accessed. This in turn speeds up the responsiveness of your editing software. Well, PCI sound cards tend to have lower CPU utilization rates than ISA, which in turn frees up more CPU time for compression and decompression. This lower CPU utilization also tends to create videos with better sound synchronization. Video capturing and editing are just plain space hogs, so get the largest drive you can afford.
