Can anyone else with a HDR set confirm at this stage that madVRhdrTestFinalColor4.zip is producing a picture with far more depth, contrast, and better tone mapping than the latest version (today)? Maybe I am misunderstanding the latest builds in terms of what it is trying to achieve - are the latest builds purely about trying to restore detail, or is Madshi, using the results of Color test builds, and now on to restore details?

Forgive me if it's a stupid question, but on a HDR set, madVRhdrTestFinalColor4.zip is producing the best image of all test HDR to SDR builds to date (100, 100, 100, 75, 50, 25, off, off)

Hi, you made me try the beta / testing build and is it me or i find the colors to be less good than the official build ??

in HDR passthrough , the colors look a lot more like the official build.

newer cards, better picture qulity?
folks, there's a question confuses me for years...

well, if my AMD card doesn't support 4k/HEVC/x265 hardware decode, like hd7000, but it did supports 4k output, means you gotta do software decode, which is ok, and it's GCN1 and UVD4

what if
if I buy the latest Vega, vega is CGN5 and UVD7, supports hardware decode (hevc etc), what if compare them both under the same setup to do software decode (dxva turn off), should I get better P Qulity with the more advanced Vega? UVD7 man

No, how you decode it has no effect on quality.

Yep, madVRhdrTestFinalColor4.zip is similar but slightly tweaked and is ok with the settings I posted, but the latest test builds certainly seem to have lost their punch.

madvr high qulity setting for down and up scaling requires tons of memory of video card ain't it? I press Tab in potplayer showing that my card's memory been eaten up 100%, 24fps drops to 6 (after choosing inferior options makes everything smooth), all in all madvr is a "GPU"-need program, depiste being dxva-off, but still needs tons of GPU power

should upgrade to 4GB card, or even 4GB isn't enough

Is smooth framerate conversion the most CPU-intensive feature?

CPU-intensives are fine, greatly fine

depends on the output resolution it has been over and over repeated to use 4 GB for UHD.
even 1 GB can be fine for FHD and 2 are totally fine as long as you are not changing the queue for what ever reason.

madVR SM doesn't use the CPU.
i guess the most CPU depend feature is either HDR peak brightness measurement or IVTC.

madshi ask about HDR subtitles in the github of libass and well... he was shutdown hard by one of the mpv developer that clearly doesn't want to have anything todo with HDR. so HDR subtitle handling is currently in a bad spot. so you have to hope that the ISR in MPC-BE will have a fix one day or cyberbeing is saving subtitles yet again.

what do you mean by "proper", explain your problem in detail, also where does the CPU come into this, are you not using GPU decoding?

actually my first impression was that madvr almost doesn't use CPU at all, it's so GPU-esque, we gotta go straight to 11GB memory card

Color are not so "vivid" like when i play the same video trough usb directly on the tv, or using plex.
I don't have a dedicated gpu, ryzen 5 has integrated vega 11 graphics

It is definitely improved. I wouldn't confuse high saturation with HDR. That is not the intent of HDR. The old algorithm was oversaturated and overall hue accuracy is better in the screenshots I've compared against other HDR and SDR references.

Pop in the colors doesn't tell me that it is accurate. New OLEDs like the models from Sony and Panasonic render HDR images with less saturation compared to LG OLEDs because they were tuned by colorists to be color accurate. The most common complaint with the previous tone mapping was that it was too saturated.

The extra punch with HDR highlights in that build was causing artifacts and a loss of detail, so it was toned down considerably. It was maybe too much image pumping.

I think it could be an issue with current AMD drivers after the troubleshooting you've done. Does changing the color gamut in calibration change anything? It shouldn't do anything, but some AMD users find changing this setting changes the output of madVR.

Did you confirm in the madVR OSD and through the information on the TV that you are in fact playing an HDR source? Does madVR report the mastering display peak brightness in its stats?

Hi, yes, as Warner states, There is a bug with all drivers drivers since 16.8.1 which overblow the colours in movies when playing SDR content at 23hz, this isnt appearent at 60hz or HDR material or if you , is this what you are fining, is everything red and overblown?

This may only affect RX cards I cant speak for none HDR cards or Vega.

EDIT - i've logged the issue with AMD a few weeks back at the same time I logged an issue with HDR failing to toggel after 18.3.4, the fixed the HDR toggle with the latest driver, hope to see the colour issue fixed at some point.

What i'm not sure about though is whether upgrading to WIN10 1803 will fix that or not, but i'm not going anywhere near that

With color gamut you men the color depth in radeon sw or there's an option in madvr?
Sorry i m a bit noob
Here's the stat while playing a 4k hdr sample

Sorry english isn't my first language and i can't understand the meaning of the word overblow ^^'
I don't have problem in sdr, only in hdr. Color are normal, there's no red tint or strange dominant, the global iamge is only less vivid, strong, like when i play the same file with the tv internal player.

OK, so your problem is with HDR material, is it all washed out, do you have a HDR TV or are you doing a HDR to SDR conversion in MADVR?
