Last week we discussed how to figure the amount of storage space you need for non-linear video editing. If you missed it, you'll find it in the tutorial archives, here . In this second part of the tutorial, we'll look at some of the storage media suitable for non-linear video editing. For a desciption of data rates for the various compression schemes, see the following table. MBps Jazz drives are also suitable for lower data rates.
Some video cards support dual-stream.
If yours does, your disk system must be capable of handling twice the data rate of a standard video card because the dual-stream card is processing two video streams at once. Setting up your own system is not difficult but it does require that you do your homework, study what's available and decide what you need in advance. While you're deciding, don't forget to consider what you may want to do in the future. Building a system just for, say, Web video or CD-ROM may mean starting all over if you need to produce DVD or broadcast video in the future. From personal experience, my advice is to overbuild your non-linear system because you never know when your needs will change.
