Interstellar - ColorMatching BluRay to 70mm
Time

Watched the whole regraded movie, and it surprisingly (even to me!) worked very well!

Despite the cool tints seen in the comparison, I didn’t expect it to be quite warm indeed; every shot was spot on, color wise, in particular of course the “water” planet - the blue cast added to many IMAX shot helped a lot there.

Are you curious to see the differen color grading, or aspect raio, of a movie, but don’t want to watch it all? Well, just take a look at “a whole film in an image” GIFs and screenshot comparisons!

(warning: big images, it could take some time to load’em all!)

Interstellar - ColorMatching BluRay to 70mm
Time

Thanks!

Although some scenes would have unnatural colors, we are talking about a film, so… if you think about it, maybe 90% of action Hollywood movies released in the latest years have some (or all) of them!

According to my (brief) tests, it seems to work well, but I should watch the whole movie (still encoding) - even if, to be honest, after few minutes the brain “set up” the white point, so it will say to my eyes it is OK, even if it’s not… 😄

70mm cells: I took your picture as inspiration because, reading what you wrote about, it should look like a lot close as it is when watched live; but don’t know about those other cells, tough… pretty sure they were scanned without too much care, so can’t be trusted as color reference, unless the scanner have done a good job like you, and wrote about it!

Nevertheless, it would be nice to have a look at them, and maybe discover that they match your 70mm one!

Interstellar - ColorMatching BluRay to 70mm
Time

Lately I’ve tinkered with few “de-tealized” projects, and learned some new techniques; so, I’ve decided to give Interstellar a go…

The “inspired by 70mm” is a color grading made in Avisynth - no LUTs or color matching; I could make it even closer to 70mm, but in that case there would be white clipping, so I’ve chosen the best compromise, and it works well, it seems:

take a look at the comparison for the whole movie:
http://screenshotcomparison.com/comparison/216927

I’ve also compared it to the camrip - that is faaar to be considered a color reference; indeed, “as is”, it’s different (a lot) from BD and regrade; when adjusted (saturation lowered, magenta blanket removed, levels tweaked), it resemble sometimes the BD, sometimes the regrade, sometimes neither… and it happens also for subsequent shots - I suspect the autowhite and/or autogain are involved. But the fact that often is closer to the regrade than the BD, and that some members remembers (pun intended!) the colors in the theater to be closer to the 70mm scan may means it “could” be “right” - somehow…

I’m perfectly aware that it almost never happen that a single regrade setting works for a whole movie, but in this case it seems to work; still to watch it all, but I’ve tested few shots, and they look good; preparing a low def version and I’ll watch it in the next few hours, then I’ll write my conclusions.

I know that for each project (and one complex like yours in particular) there are so many thing you have to check/tweak/test etc. - but it improves with time and experience, usually… 😄

Clipped white: I’ve seen it, but, as there are “nothing” to recover there, the only solutions I can think of are

  1. find another source (even with lower quality/resolution) and replace the blown highlights parts with it (using a mask)
  2. if there are no other sources, you may prepare a lower contrast/brightness version, and again replace blown highlights with is using a mask - so you will not get “blinding whites”! 😉

I liked it! Can’t remember the original version exactly - I watched it few years ago - but your version worked very well, as it’s seamless (apart the repeated frame that was fixed as you wrote); that’s a bit like the best CGI effect, when you can’t say if/when it was used - it means it works!

Some notes:

colors: I like them!
subtitles: I like them out of the picture - probably I’m one of the few, though… don’t know if you plan to hardcode them, but I’ll go soft.
problem: the first shot after the credit (the car) is affected by deinterlacing artefacts.
hint: I’d stretch horizontally the first credits - the one you used with starfield as background - to resamble better the following credits font size and aspect ratio.

While original is too hot, with that teal sky and orange sand, your version is still too cold - we are in the desert, after all!

Try something in between - can’t say exactly 50/50, but certainly it need to be warmer. IMHO of course!

Too hot here to have the brain working right… seems to be on Tatooine… 😄

Let’s wait for a lower, human-compatible temperature!

The whole wormhole sequence has me scratching my head. On the secrets of Stargate CD-rom there is an Extended wormhole sequence (original animation) but it is running at 20fps with frame drops.

It’s always possible to create missing frames using interpolation - sometimes it works really well… you can give it a try!
