Why does it increase the rendering time?

HDR Anomaly
I have been testing HDR on the latest build passing thru metadata. HDR mode kicks in perfectly, unfortunatley it gets stuck in HDR mode until I reboot the PC. Is this a known anomaly?

All the movies in Nolan UHD set and upcoming Batman/Returns/Forever/&Robin UHD release. Harry Potter UHD releases. There are more, and Warner Bros is the worst offender.
Note that none of these movies had orange-teal grading originally - even in their BD releases. This is something the studio did *after the fact* for 4K releases to make things pop. But it looks awful, not to mention it is not Director's original intent. Quote:

I am dealing with 4K tone-mapped video on a native 4K display, so processing starts to get really extreme when it has to upscale chroma and luma and do tone-mapping. Normally there is no luma upscaling because its 4K native on 4K. And when it's 1080p video there is no tone-mapping because its SDR. It works if I set chroma and luma scaling to Lancosz AR for instance. But if I set chroma and luma to NGU sharp medium even it's like 80-100ms render times even on a 2070 or 1080. There is no way to make this work without using the anamorphic stretch I'm guessing. The whole zooming away black bars stuff is what makes it only work if I fill the 16:9 panel with the 2.40:1 video via anamorphic stretch factor 4 / 3. I wish madVR just had a simple image cropping option that didnt require this zooming stuff and just took the picture as is, 1:1 on the screen, and allowed to cover the edges with a specific amount of black like some projectors allow.

Can you do a blind test with an assistant? See if you notice an improvement from NGU upscaling compared to Jinc.

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.
