What You Need to Do It

Instead of using tape, nonlinear editing systems rely on the processing unit, random access memory (RAM) and hard disk of a computer to manipulate and rearrange the video and audio information. (But this information has to be all-digital, which means it has to be digitized from tape, or directly from a camera.).

 For non-linear, desktop editing, youíll therefore need the following:

  • A video source - video camera or VCR, providing the best quality video and audio signal possible
  • A computer - to do the number crunching (yes, digital video is extremely crunchy, so the faster your computer and the more RAM it has the better)
  • A video and audio card (this card is distinct from the video card that drives your computer monitor) - for efficiently digitizing from tape and/or outputting digital movies to tape
  • Plenty of disk space - to store your movie and audio clips (remember, even the smallest, compressed video clip lasting about a minute can easily take up 2-3MB; multiply that 10 times for full-screen, compressed digital video)
  • Software - for controlling the digitizing process, editing your video clips on a timeline, inserting transitions (link to below) , rendering the final assembled clips into a continuous digital movie, and outputting movies to videotape, if thatís called for.

 Itís not our intention here to provide detailed specifications for the above items. The variety of systems out there is increasing, while price-performance continues to drop. For more information, see the Webliography(link to appropriate doc. or part of doc.), as well as the sections on shooting video, hardware systems, etc. (link to RZís sections, as appropriate)
