[QuadList] Grass Valley

[C. Park Seward]

Hi Chris,

Kinda of. Some of the patented processes were licensed but not the entire process. A chroma keyer is not an Ultimatte. As you know, the Ultimatte uses a color-difference method that is very different from a chroma keyer.

Some sophisticated linear chroma keyers claim to be able to reproduce transparent objects and shadows cast on the backing while at the same time removing blue spill from the foreground subject. In practice, however, they cannot create a composite that is as realistic as an Ultimatte composite in many situations. Smoke, reflections, out of focus objects and extremely fine hair detail will not look as good in a composite made by a linear chroma keyer. Shades of blue will be difficult to hold in the foreground and will turn gray in a chroma key composite while they can be held and accurately reproduced by an Ultimatte.

Take a look at this page of the control panel:

http://www.ultimatte.com/UltimatteMain/SR2_Main.html

Without those handles, you can't get the "Ultimatte look". 

I don't know how many times the readers here have used the Ultimate for real paying clients, but I've used the Ultimatte HD to composite Johnny Depp and Matt Lauer and Al Roker of the "Today Show". I know a good composite.

The demo I saw at Grass was of a tape that was very yellow, perhaps trying to mask the blue spill. The white balance was way off.

Best,
Park
