GOUT Technicolor regrade (single pass) (* unfinished project * - lots of info) — Page 3

By adding an additional technicolor reference, I’ve been able to further improve the accuracy of the regrade (I’ve also further optimized the saturation levels):

I’m also preparing a sample video, which should hopefully be available soon…

It looks good but are the color supposed to be this dull if so really great job. 😃 Also the trash compactor scene is it just me or is that black crush?

While very possibly technically accurate, the regrade doesn’t look enjoyable to me with that much green.
Although I guess that this topic is more about accuracy than aesthetics…

Once we have what I believe is an accurate representation of the technicolor colors for the entire film, it should be relatively straightforward to balance out the green, and obtain a good approximation to the 1977 theatrical colors without the typical technicolor green shift. I will create a second GOUT regrade for this purpose.

So, in the end this project should yield two GOUT based color references next to NerverarGreat’s bluray regrade (which is also based on technicolor references), that can all be used to perform shot by shot color corrections for future HD releases or faded prints.

The contrast is somewhat higher, but the contrast for the GOUT is very low, because it was meant for laserdisc, which generally have less contrast than modern day transfers.

Ps. The GOUT is also oversaturated, particulary the red.

If your assumption about the (red ?) faded internegative which would have been corrected by one pass was confirmed (and that make sense), it could be interesting to test something : to come back to the original color by crossing the road in the opposite direction.

  1. Reconstructing the fading (it would be the hardest part and imply a lot of observations and suppositions about the balancing process applied for the Laserdisc)
  2. Restauring the colors by using your famous tool.

😃 I see what you did there… but I won’t tell anyone. Those look nearly flawless Dr. Dre.

I liked the previous “green” version more. But I guess you can’t please everybody 😃

They look decent, but add me to the group that liked the previous grade better as well. These are coming through just a bit too dull, where the previous grade “popped” - Technicolor may have always been a bit green, but it was never dull or washed out looking.

Preferred Saga:
1/2: Hal9000
3: L8wrtr
4/5: Adywan
6-9: Hal9000

It’s just a matter of saturation. The saturation levels are not final. I will increase the saturation somewhat to get more pop as you call it. They do look a little washed out now.

Yes, this looks much better. I like it. I think you’ve nailed the colors.

Yep, I like the latest regrade as well!

I concur with the group…looks great!

This is looking really good, DrDre. Amazing how one set of corrections seems to fix the entire movie.

Can you post screenshots of the sunset scene? As I recall, that one looks quite different in the GOUT than it does on prints, so I’m wondering if this one correction will also fix it, or if it might need a separate one. That would determine if it had been changed deliberately or if its difference is just a consequence of the global color pass they did…

Placing bets now! My money says the correction fixes it to match the print.

I hope you keep them at DVD9. I cannot wait to see a good solid release for these.

Thanks to DrDre and everyone else for all the work and care taken.

I’ve tweaked the color grading somewhat, and for me it’s now perfect. Here are four sets of sample frames, including the binary sunset:

Hmm . . . the sunset scene still doesn’t look like the prints. I didn’t think it would; apparently too much blue/purple has been added for a single correction to get it back. The only other problem shot I see is the first shot of Artoo in the canyon being excessively red, but it’s like that in the GOUT already. The rest of the movie looks fantastic with the adjustments.

Well, we actually don’t know exactly what it looks like for a projected print, but it’s really close to the the Senator print photo, which is a bit brighter and more saturated, but also purple:

The R2-D2 canyon scene actually is excessively red for the technicolor print scans we have, and the -1 LPP as well.
