Don't use k-lite. Perfect work in MPC-BE + MPC-VR.

what i must use?? i don't use mpc be i think is a bug, with klite 18.3.0 the colors are perfects

[Aleksoid1978]

K-lite is a garbage dump.

[djsolidsnake86]

K-lite is a garbage dump.

I tried mpc be and klite 18.3.5, same problem only klite 18.3.0 give the right colors with rtx hdr (the problem only occurs in some videos)

i found this: https://github.com/clsid2/MPCVideoRenderer/releases installing this version of mpc video renderer on 18.3.5 give right colors so the problem is the video renderer

Maybe caused by one of these changes between 2233 and 2250: https://github.com/Aleksoid1978/VideoRenderer/commit/7775461cedc48e3855de91fc4f4bb977d36dbc0d https://github.com/Aleksoid1978/VideoRenderer/commit/7397ad2e516592858ef37adb8e2a95ca54ef9a32

Does it also happen if you disable SuperResolution?

If VP resizing is disabled for HDR passthrough, then it should not request SuperResolution?

This should help narrow down.

2243 is good, problem happen in 2244

[clsid2]

Try this one: MpcVideoRenderer64_rtxfix.zip

Changed 7775461 to skip VP resize for normal HDR only: m_bHdrPassthroughSupport && m_bHdrPassthrough && !m_bVPUseRTXVideoHDR

this is to use with last nightly?

[clsid2]

Just overwrite it. This is 2251 plus potential fix.

Does 2244 work if you disable SuperResolution?

nope, oversatured colors

[Aleksoid1978]

Sample is unavailable. I test on my videos - all is good in MPC-BE and MPC-HC.

[Aleksoid1978]

Try this build. MpcVideoRenderer-0.8.2.2252_git2024.06.04-8b2c5ed.zip

with this i have a crash of mpc hc

[Aleksoid1978]

Since it is just a standard 8-bit sample, perhaps behavior difference on your guys systems might be due to different driver version?

And given that my workaround/fix also worked, the issue is likely related to resizing. @djsolidsnake86 Does the problem also occur on the broken versions when video is viewed at 100% size (so no resizing)?

yes i have always the last driver versions, but problem started from 18.3.5 klite (the mpc renderer of that version) not from updating nvidia drivers
