to my eyes this not minor here i can clearly see 8 or more steps on the back and i won't be shocked that it comes from double expending.
maybe that's the case with normal on this film stuff i don't watch stuff like this usually and i have debanding disabled by default. i now at least one scene where debanding low is kind of ruin it. |

Maybe this example convince you more (off/low/medium/high) :
Open in original size of you won't see anything. Banding is still very noticeable on the top-left side with the "low" setting and you can clearly see here the details lost on the bottom of the image in the trees with the "high" setting. Last edited by Neo-XP; 5th January 2017 at 22:57. |

Also their whole processing is interesting The Encoder on the outside here is ATEMEs Titan which does pretty good Atemes Encoder pretty much dominates most of the Demos, especially LG and Samsung.

it is possible to create a smooth gradation with hat sky.
the banding is so terrible it can't be fixed with debanding completely but it is still a mastering issue not a recording. 8 bit is more than enough to show this smooth. |

Memory can be lowered by lowering one of the queue, probably render or present, can't remember. |

and even if you run out of Vram you can still run madVR but performance get's bad but that doesn't mean it will go over 40 ms. |

Didn't know that madVR can force a change on the windows timer

There are more things to consider here. If you're building a computer solely for madVR and video watching, a quad core or even dual core might be enough, but iGPU won't do that much for madVR either way. If you want to do other things, depends on what you want to do. Quote:
MadVR doesn't use much GPU by itself.

Do you have a Native 10 bit Panel or 8 bit + FRC ? Anyway Debanding is not a solution but a workaround and im pretty shocked that some find debanding the whole frames efficient same they like to enable dithering (i hate both and want it to finally die) @ huhn Of course you can do it better but that source is ok , anyway all these 10 bit demos will come out the most efficient on a real 10 bit Hardware chain that's fact and you know it. You can throw Debanding and dithering over it and Destroy the result but that will stay a workaround nothing else that can be percepted (and has many issues) on a 55 UHDTV immediately your debanding and dithering will fail in such high gradiation recordings at that output Size especially in Motion you never get that transitiion band free 10 bit wasn't introduced for nothing and consumer can jump around that it's finally here.

If madVR's debanding can remove it the banding is probably from the source, not the display.

Okay then lets compare hope you guys are also correctly calibrated to bt.709 in that case
This is what all UHDTVs in the middle class reach by now mostly perfectly and it has some impact on the final result if you wrong calibrated you most likely would see less banding because you gonna percept less details especially when your luminance is off and we talking about HDR stops here that will be recorded in the future by AVG Joe. So lets see Spatialy 8 bit out no debanding 8 bit out debanding low (spatial/temporal) Bands doesn't get completely eradicated looks still bad as before just some noise added which pushed up the filesize hurray 8 bit out debanding medium (spatial/temporal) Filesize obviously gets higher it's bruteforce time 8 bit out debanding high (spatial/temporal) Bruteforcing moves back a bit

It looks like there is bad banding in the source?
debanding is for smoothing out banding present in the source, not preventing banding due to low bitdepth output. New TVs might also have debanding capabilities, it is a very common problem.

Of course its a very common problem because their is no real 10 bit chain working but you need that debanding wont help, the demo was exactly done to show that and Samsungs Native Gamut Range.

Would be nice if you could confirm it is indeed the source which UHDTV is it exactly ?

Phantom Flex has also lot of scenes that can band extremely and MadVR has no chance avoiding it
http://demo-uhd3d.com/fiche.php?cat=uhd&id=98 This footage is also partly used in "World in HDR" and SES Astra Demo Same for Powerofcurve http://demo-uhd3d.com/fiche.php?cat=uhd&id=148 It's also very visible that the Computer Generated stuff allways comes out better then the almost untouched natural light shoots Ride on Board banding example http://demo-uhd3d.com/fiche.php?cat=uhd&id=97 So it would be really nice if you could confirm that what i see is what you see on your 10 bit chain or to disconfirm because it makes no sense to show this 10 bit progress to the public if the sources are all wrong Everyone would realize that on such big screens with a bad 10 bit chain and calibrated. And im Pretty sure Ateme knows what they doing when it's about 10 bit
