Released Mad Max (1979) original color timing & mix
#41
Made a test clip (using same footage as the previous one); this time, source is the UHD WEB, regraded using DVD as color reference:

(3840x1640 23.976fps HEVC, 33s 160MB no audio)

the most difficult thing is to get a nice picture to start with, from the HDR... I used the HDRtools plugin for avisynth (https://forum.doom9.org/showthread.php?t=175488), following is the conversion - I guess it could be better, but so far is the one that produces "less worst" result! Big Grin

Code:
ConvertYUVtoLinearRGB
ConvertRGB_Reinhard_HDRtoSDR
Converttoyv12(matrix="PC709")
ConvertTo8bit

Watched it, I think the colors still look artificial. The HDTV as much more filmic quality, here I can see the manipulation that was made to the colors and it doesn't look organic.

I don't think the source scan, be it 2K or 4K, can't be nicely converted to the original print look. For me it's the SD and HDTV.

HDTV desubbed will probably be the closest one can get to a great version of this film.

Why do you take the luma from the HDTV? Just adapt the tone mapping parameters to make the UHD brighter. Wink

I think a good way could be to color match shot by shot using Resolve. (you can detect cuts with Resolve)

This.
The 10bit Web Rip (even with its compression) can surely give you better results than patching burnt in subs on a HDTV capture?

I think the 4K is as flawed as the BR as it looks video.

Resolution and more framing makes no difference if the film doesn't look organic like a film print.

Sure HDTV may lack in resolution, but it looks 100% like the original film.

My comment was not based on Resolution and more framing.
More on the extended color information in the 10bit and Rec2020.
Down converted to HD Rec709, using the extended color information to sample to 4:2:2 (even 4:4:4) would give a really nice file to work from.
Would the 'video look' not be corrected with a 'regrade'?

The work would have to be done anyway (even in script form) to use it for the patching!

Ive not seen the HDTV so Im not sure what problems the BD and 4K have in comparison.
Although I get what your saying with the organic look, its always been something that can be corrected with some work.
What PDB did with DH3 is a prime example, and this is nowhere near as bad.

Oh I think the BR is worse than DH3, and the 4K is the same master.

Problem is both the R2 DVD and the HDTV are from obviously an IP or interneg with the color timing baked in.

To match exactly the IP or IN look is I think really hard. I think it might be good I give a try and order the Australian BR, in case they use the same master as the DVD. I will be able to do this next month.

Cool.

Is your SD version available or are you holding back on it for the HDTV version?

Agree that HDTV and DVD have the best overall color, and that the regrade is less-than-perfect; still, it has more details, and the regrade could be improved, when (if?) I (someone) will find a better HDR->SDR conversion method.

As the HDTV has the smaller frame size, the UAR version is better - not bigger as BD or WEB, still a bit bigger than HDTV; the minor problem is it has small "empty" corners that happen sometimes; as they are so tiny, they could be filled with the so-called "ambilight", yet in a very limited occasions, those filled corners "bleed" outside, into the black borders; I hereby ask someone that would help me to find out those few instances - I'll fix them; if someone would chime in, I'll start to encode.

Non-UAR version in this case is pointless, because AutoOverlay is needed anyway to align the DVD and HDTV to get rid of the subtitles, and when the empty black corners are filled, I dare anyone to recognize where (and when) they are!
