Agreed. For my purposes, I'm investigating whether the GPU is dithering, 
and if so, how exactly it's achieving this. Part of the process involves 
taking luminance measurements of different test patterns. Being able to 
encode these patterns into a movie file, so I can step through frame by 
frame, is critical for reducing the amount of noise in my measurements.

ah, thank you!
