Re: Monitor calibration/profiling for video applications
Thanks for the info Tom & Graeme. From the research I did I read a fair amount about the Rec. 709 standard and saw that it seems really close to sRGB. I was surprised when the guy behind LightIllusion claimed it was a much higher standard than used in the stills industry. From there most of what he was saying seemed to rely on buzz words and claims of superiority while providing very little in the way of specifics. This past Spring I took a class in high end compositing using After Effects. The teacher was a senior compositor at one of the top VFX shops in the LA area and again I was surprised at the haphazard way color management is used in the motion side of our industry. It really seems that the implementation of color management is about 10 years behind the stills side and while I recognize there are a lot of complicating factors it still seemed shocking that it's so poorly implemented. As I learn more about the motion side these questions keep coming up and it's good to know this list can be a resource for getting some of them figured out. Thanks!

Beware - Rec. 709 is an encoding standard, not a display standard. There is a deliberate gamma difference between encoding and the typical CRT displays that are expected to be used with Rec. 709 that compensates for expected viewing condition differences (see Charles Poynton's "Digital Video and HDTV" for more background on that.) So you never want to calibrate a display to Rec. 709, unless you make allowances for the viewing conditions, typically by increasing the gamma of the display over Rec. 709. [I would imagine that many people in the Video industry are woefully unaware of the role that viewing conditions play in the standards they deal with.] You might want to investigate ITU-R BT.1886 which is a display standard.
