with the screen config "define visibile screen area..." you can add black bars and you are cropping the rest of the image. which is BTW. the opposite of what you wanted before. |

If you need to reduce image upscaling, create a separate scaling algorithms profile for 4K content and set it to Lanczos3 + AR. In the end, you should end up with more pixels if upscaling is involved, so it should be worth it. A 1080p profile could use NGU image doubling. I know there is at least one other person out there using the anamorphic stretch with tone mapping with a lesser GPU. He said he was using a similar combination.

The yellow look of The Prestige was debated several times in the HDR -> SDR tone mapping thread. Many insisted that the color correction from tone mapping must be wrong, but I think that look is authentic to the original source material.

you can easily test anamorphic lens with any TV and show that you don't need a high end GPU you just need to understand what you are doing. or with other words don't use settings that work without an lens they are very different.

Does it really take that much upscaling just to correct a small portion of a 2.37:1 window? The ratio is almost identical to 2.40:1 by a few pixels. The anamorphic stretch on the projector should do the rest.
I don't know what upscaling is involved with the anamorphic setting. You seem to be able to apply it with or without screen masking, which creates different sized images. The one who told me they were using the anamorphic setting with tone mapping was using something like a GTX 1070 with a special profile for 4K content and upscaling to 4096 x 2160p.

i give you the none complicated example missing out a lot of parts:
3840/21*9=~1646 that means you are upscaling an 3840x1646 image to 3840x2160. that's a lot of work and with doubling not much fun for the GPU. but it's get's better projector are usually 4096x2160 so if you mess up the settings it's doomsday depending on your setting you may double 3840 to reach 4096. |

- apply orange to mids - apply teal to highlights and shadows So it would require undoing this, and it would probably be hard, maybe impossible. however madshi does tackle hard things with ease :P Quote:
dark knight bluray dark knight uhd interstellar bluray interstellar uhd There are many other 4k rescans from older films, where colors are very accurate (bladerunner, ghostbusters, etc). Warner Bros is clearly applying teal/orange to make things pop. If movie has that look originally (for instance Transformers), then I have no problem. But this change from original material needs to be outlawed. Quote:

Cropping the movie won't change the aspect ratio of the pixels and the height of all aspect ratios is the same. I would think applying the projector's anamorphic stretch to the image cropped from madVR would result in the correct pixel dimensions if the anamorphic scaling doesn't know the aspect ratio of the source.

so you should always use as much pixel as possible. |

Warner is doing it again for the upcoming Batman releases (see screenshots) This is done on purpose. Teal & Orange grading is a thing in hollywood nowadays (read more about why they do it here). I am ok with the artistic choice for a new movie, but I dislike it when they retroactively apply it to an older one that did not have this look before. Quote:

Even if you created a system that scans every frame and changes colors "on the fly" (a kind of "dynamic color grading"), the end result would probably be shitty anyway because your picture is not raw "flat" neutral footage, but already color graded. One of the many problems I can think of is that teal & orange color grading often purposely crushes blacks you obviously can't "uncrush" with color balancing : the details are already lost. Maybe a talented colorist could mitigate the teal & orange look by manually recoloring the movie shot by shot, but I don't trust an algorithm to understand what looks good to human eyes. Anyway, if you have an algorithm that can do that, I suggest you call Adobe, they'll buy it for sure Of course, I'd be happy to be proven wrong, but in the meantime, I'll take a carefully graded teal & orange picture over an awkwardly automatically desaturated/recolored one a million times.

would switching white balance to a cooler setting negate some of the yellow grading or would that be too course, I noticed this a lot in the 4k interstellar release, I much prefer the 1080p bluray.

I have the same with FSE, did you use FSE? If so then try fullscreen window mode (FSW).

Take Interstellar. This page has comparison screenshots between 1080p & 4K releases : https://archimago.blogspot.com/2018/...-ray-does.html You can see that some shots are heavily altered, while some others are not modified at all. Even if modifying white balance actually worked on the shots that most bother you (and TBH I highly doubt the result would look natural...), every other shot in the movie would probably end up blue-ish or looking unnatural in a way or another.

The Human Touch, ruining our movies.. Damn you colorists, y you need so much teal..
if y'all just bump up color temp to 7000-7500k it should take alot of red/green out of the picture. For example it works well on the latest Broly Funimation bluray Best done via 3D lut, otherwise the overall balance will be very odd looking. The bulk of the problem is most likely the studio upgrading to very different grading monitors . The new sony and dolby hdr sets. There's going to be a rough patch in releases for a while, before they dial it in.

Read one post above yours. This is often done scene-by-scene, and such a broad approach would ruin the scenes that don't have this treatment.
