Usually, adjusting the images in DV systems is a very difficult process. When editors need to adjust the brightness or white balance for all the footage in a production each clip has to be rendered. This takes a very long time, even with today s powerful PC systems. They are much more important than, for example, 3D transitions that editors rarely use. Of course, stability is another important factor of productivity.
Editors can accurately estimate editing time only with a stable and reliable system.
The second crucial element of real-time editing is maintaining image quality. Professional video editors will not accept these schemes. Many systems use the RGB color space instead because it s simpler and cheaper to build into the system, but it doesn t maintain image quality as well. This is particularly noticeable with bright colors. The main reason for using DV format is because of its high image quality.
