For clarification:
The "data" output of the viper  is 4:4:4 RGB. We could not shown live 
images from the viper on the screen in the film imaging module cause the 
input of the projector was 4:2:2 YUV. We had no  in-a-box 4:4:4 RGB to 
4:2:2 YUV converter (if there is one at all), so we fed the images through 
the Specter. Big advantage of this approach was  that we could feed the 
signal through a color corrector too. As a contribute to Geoff Boyle, we 
mainly showed his sunrise shot but others like a shot out of car on the 
strip in the night had been on the screen too.
