- I am not sure how relevant it is to the CMS, but I did this work with a custom gamma curve with the gamma correction set to 2.3 and values tweaked along the curve as needed to fix the tracking below 20% as well as to improve 70-95%. This measures to a 2.2 gamma. If you do not have the capabilities to set this up do not worry about it as it may make only a marginal difference (tho I can't be sure).
- Set the Color control to 0
- Set the CMS settings as follows:
Color, Hue, Saturation, Brightness
R: -2, -15, 9
Y: 3, -25, 15
G: -10, -25, 13
C: -1, -30, 6
B: 0, -10, 15
M: -1, -12, 10
- Reduce the color control to taste, if desired. I like it right at 0. However if you find Rec Ldvd to be a bit more over saturated than you'd like, drop color down a bit. This will also help remove clipping (generally most clipping is gone by -4ish) and help tame green a bit more, but keep an eye on your sky-blues and yellows (in particular) which will start to flatten out with a reduced Color setting to actually be undersaturated compared to THX mode.
These settings are the work of approximately 60 hours
of experimentation, redos, and tweaking to wee hours of the morning over and over, and is based on the input, theories and feedback that many here have shared for which I am very thankful. I hope you enjoy these and only ask that if you repost these settings elsewhere you provide credit to AVS forum members, and that one day Chris takes me for a spin in his toy.
Of course if I had to do it over it would take a lot less time with the hindsight of everything learned, but surely I hope I never have to do so!
We can't be sure at this point that CMS settings are transferable from machine to machine, but unlike grayscale tracking, I anticipate it should be (as an example I think we all have the same CMS settings for preset modes like Natural etc, although I don't think we ever verified this). If not, then I previously outlined the approach I used, and keep in mind the approach for CMS Setting 2 was the clear winner.
Also I should close by saying that while I am finally happy with the colors, it is not a substitute for a fix and/or better implementation to the CMS which is still sorely needed. I view this as a temporary (hopefully) work around.
The fact that I like colors a bit over saturated played well into the balancing act made possible with these settings, but for those looking to dial things in right at Rec 709, I think it will be even harder to find a good balance.
Please be sure to post your impressions on how these settings look on your RS20 and whether you change the color control or prefer it at 0. I look forward to your feedback and suggested tweaks to the settings are of course very welcome and encouraged. Enjoy!!
