Potplayer & HEVC HDR 10bit

jedi93 · 28th February 2018, 00:15

Can Potplayer (or MPC-HC) display HEVC HDR 10bit correctly on a normal 8bit PC monitor? Without the need of madvr?

What would I need to do to get that working with the smallest possible CPU/GPU usage on my system? http://speccy.piriform.com/results/o...5PAAHAg1btjWyC

What's wrong with MadVR?

jedi93 · 1st March 2018, 18:33

too resource intensive?

Resources are there to be used and spent. What are you doing while watching HDR video that you need a lot of additional resources for? Any solution for HDR-SDR conversion would take some resources...actually, GPU usage is less in MadVR with HDR conversion than in EVR with no conversion...I get 10% CPU and 50% GPU, and that's a Core 2 Quad Q8200 with GT1030 2GB, you can't get much lower than that...your system should squash that like a fly

I just don't like hearing the fans (at all) if I'm watching a movie or something... The usage itself seems okay, CPU 20-40% and GPU 30-50% ca.

Also, for some reason, in Potplayer madvr shows "HDR, unknown properties" but in MPC-HC it shows "HDR 4000 nits, BT.2020 -> DCI-P3"; both times it's the same file.

BTW: what does "DCI-P3" mean?

hm...
SHOULD it say DCI-P3 if it's a normal, non-HDR display?

mytbyte · 1st March 2018, 21:14

I'm not sure but I think DCI-P3 is just an info about the color primaries of the grading monitor, not colorspace transform...what decoder filter are you using in pot player?

I'm sure you can control your fans from BIOS or software...

jedi93 · 1st March 2018, 23:56

I already got something for fan control, that's not really an issue.

I just use the built-in decoders for everything (where possible).

The line "HDR 400 nits, BT.2020 -> DCI-P3" means madVR is getting all the HDR metadata properly and the file has a peak brightness of 400 nits and is encoded as BT.2020 with all colors within the DCI-P3 gamut (it should be displayed on DCI-P3 display for best results).

The line "HDR, unknown properties" means madVR is not getting all the HDR metadata properly.

jedi93 · 2nd March 2018, 14:44

but why doesn't it get the HDR data properly in Potplayer, but does so in MPC-HC?

btw it was supposed to say 4000 nits, I edited my reply :P

because the potplayer devs didn't have the time to steal the code from lavfilter yet. they simply didn't add that feature.

jedi93 · 2nd March 2018, 19:18

hm, okay.
So, is madvr now converting HDR to SDR? How can I check?

nevcairiel · 2nd March 2018, 19:55

If it doesn't look washed out, then it is.

jedi93 · 3rd March 2018, 02:50

okay, so it seems to work
