Configuration mainly pays attention to advanced cpu (dual core at least, quad core is better) and larger memory (2G, VISTA can use 4G). The hard disk is bigger, and it is better to use a solid-state hard disk. Next is the sata disk with 7200 rpm. Don't think about anything else. The actual requirements of graphics cards are not too high, and the amount of video editing and processing pictures is generally small.
Remember that the notebook must have the 1394 interface.
What matters is which software to use, adobe or Canopus, which is fast and effective.
Slower than the desktop, but can be edited at any time. Sometimes it's not a taste to do a job and go to a fixed desktop.
If you add an extension line of 1394, you can record it directly on your notebook, which is very convenient.
