Color selection for TV output
When editing video you will often tune the color ,brightness and contrast to your taste ... only to find out when you view the output on the TV it doesn't really quite look that good. Why this happens and what you can do to prevent this will be explained in this article.
The problem with handling video on a computer is that the computer monitor can handle more different colors than a TV screen can. Furthermore the Video signals don't suffer from cross modulation effects since the components are never combined. A computer video card generate independent Red Green and Blue signals. When this signal gets converted to a TV signal , either by a plug in analog output card , or trough the process of making a DVD or (S)VCD certain problems arise. In case of a (S)VCD or DVD the problems arise the moment the player reads the disc and converts the digital information to a so called composite video signal.
The advent of the S-Video standard has cured some of the problems but not all. A newer emerging standard is the YCrCb connection. Sometimes also referred to and labeled as YUV although that is not technically correct. Certain higher quality DVD players bring these signals out. And very good TV sets ( especially the HD sets ) have inputs for these signals.
