Extending the Prospect 2K work-flow on Lbs

Our next major film project Lbs will be using the upcoming Prospect 2K editing engine. Prospect 2K is a work in progress and we aren't currently marketting or selling it. I will occassional discuss the product's updates as will learn from the post-production of this film.

One of the post-production requirements is to monitor the timeline via HDSDI even though the scanned frame resolution is 2048 x 1276 , larger frame size than HDSDI generally supports (at full frame rate.) As the feed is primarily used for color correction we will window the 2K source so that most of the image (80%) can be seen across HDSDI. For this project will are sending out the center 1920x1080 image. This HDSDI feed will pass though a BlackMagic HDLink box to enable the mapping of log density image for accurate viewing on an HP 24" DVI LCD panel.

All of this has been working perfectly well. The trick now is to come up with the necessary curves between the log images and the 2.2 gamma LCD such that color correction performed, with this simple workstation setup, will match the final film out. This will involve correcting for the errors / distortions in the film final out -- we will be performing film out tests and using that data to help generate the curves. This is the next big stage of this project, and no small feat. It should be a lot of fun.

Was this accomplished?
How was it done?
I have a similar setup. Got to tweak it right the first time.
BMD HDPro > HDLink > DVI in HP2335 LCD. PPro 1.5 and considering the bump to 2.0 and Aspect sw.
