Video editing: Then and now
Thirty years ago, engineers acted as video editors. They had to. Only they knew how to handle massive, unruly, and complex tape machines. They had to monitor things such as color framing, sync timing, and blanking. Back then videotape editing was a technical task, not an artistic endeavor.As editing machines became smaller and easier to use, engineers gave way to artists, but editing on analog (non-digital) videotape still had its limitations. Each edit resulted in "generation loss," a reduction in visual quality caused by the less-than-perfect copying of the analog signal from the original videotape.Transitions, such as cross-dissolves, required the use of three VCRs and expensive switchers. Frequently the VCRs did not synch-up properly, leading to a flicker or jump-cut at the edit point.Thanks to the advent of digital videotape and software video editors, generation loss, jumpy transitionsand expensive tape machines and editing hardwareare things of the past. Now, anyone with a PC, or even a laptop, can do broadcast-quality video editing.
