Premiere is a nonlinear editor (NLE). Adding new segments, rearranging edits, and editing your story out of order all work easily within Premiere. You can add multiple special effects, use numerous transitions, and layer several clips in one segment with no concerns about image quality degradation. Premiere's timeline interface follows industry standards, so experienced NLE users readily can make the shift to this powerful video-editing tool.
One of the great advantages of an NLE is instant access to all video clips. No need for endless fast-forwarding through reels of tape. It's all right there on your hard drive.
If you use DV equipment, getting that video into your computer is almost mindlessly simple. Analog tapes can be a bit more tedious and labor intensive, but the process is still a whole lot more user friendly and flexible than editing only with videotape.
