A bit better than before, but magenta is still there… 😦
The scene by scene (or, worst, shot by shot) color grading is beyond the mission of this project; I just want to have a “set-and-forget” setting for the whole trilogy, and, using RaiTre as color reference, the results are good in almost all the shots… I mean, I could live with some magenta-ridden shots during explosions or laser blasts, if the other shots look like good; at the contrary, I can’t stand with green or yellow snow to get good colors on explosions shots - plus, even if explosion itself has better color, the other colors shift too much…
What I used for my regrading is the HDTV (and/or BD) luma, and color matched RaiTre chroma; this is because RaiTre brightness and contrast are off, and, using its luma will lead to worst results, due to both brightness/contrast issue, and the fact that aspect ratio is different and the color match script often is prone to artifacts.
If someone took time to read the article whose link I posted before, the RaiTre and DVD menus have very similar color grading, and different from all the other known versions; I think this is a nice grading; is it the “proper” one? Maybe, probably… who knows!?!
Another test I made, to be sure at least that RaiTre are not just an “auto whited” version of another grade (at least on Hoth, where the snow shots are almost all really white-ish), I compared (in a 2x2 grid) the HDTV-RaiTre regraded, the HDTV, and their respective autowhite’d counterparts; well, the RaiTre is definitely not autowhite’d; sometime both autowhite’d versions are similar, but often the HDTV is way worst than HDTV-RaiTre; in the latter, there is that touch of blue on Hoth shots that works… not too much, just not exagerated like in the HDTV (BD).
And, RaiTre is not lacking saturation in comparison to HDTV/BD, well, not always… I do love blue Executor and its red-glowing engines!
