IMPORTANT UPDATE:
I had two choices: give up, and leave The Matrix [spoRv] "as is", with its own glitches - and I must admit I'm quite happy with it, but not entirely of course - or use the open matte HDTV versions; in this case, result will be 100% perfect, color wise, but without the original intended aspect ratio...
A dilemma that *maybe* now have a solution... I managed to do an alternate color matching script, but that's not perfect as the original one...
After many months of testing and working on color regrading, I realized (maybe wrongly, who knows?), that sometimes it's not so important to make a color grading that is 100% the same of another source, but that the most important thing is to retain the "spirit" of that color grading...
That is not an excuse, as I'm still able (with a LOT of work) to produce an almost 100% identical color grading in almost all scenes of a movie (e.g. Halloween), but with some movie, the task is so time consuming that I was ready to throw the towel - The Matrix is the thoughest movie in this context...
The new attempt *seems* to be quite good; no artefacts at all - at least, not visible in the first test clip I made - and, while not perfectly the same of the DVD, it retains the "spirit" of it, with a better quality... it seems that the DVD has a pink blanket that I was not aware of before.
Well, a picture worth thousand words, so here you are some screenshot comparisons:
as you can see, there is a "compromise" where previously in the old CM there where artefacts, but I think it's still better to have some shots near, color grading speaking, the BD instead of bad artefacts with 100% right color grading...
test clip - each 255MB, no sound:
Original BD
New CM
Please take some time to do your own comparison and let me know what do you think... I'm also open to do two versions, an open matte 100% color grading similar to DVD but with wrong aspect ratio, AND a, let's say 90% color grading similar to DVD but with right aspect ratio...
Or, I could make a mix, using the new CM where I previously used the upscaled DVD, but I fear there will be too much difference in color grading between the shots...
Thanks in advance for your feedbacks!
