NEW: JRVR Video Enhancements in Media Center 30

<< < (30/31) > >>

Movieman:
I still would like to see comprehensive aspect ratio controls implemented with presets like this:

I asked for this years ago, and it now appears others here need support for positioning and sizing different aspect ratios.

Not sure if JRVR support allows this as I haven't got around to installing it on my system yet.

The last time I experimented with it, the existing scaling implementation was not granular enough and doesn't allow positioning of the scaled image within the preset.

--- Quote from: mattkhan on April 15, 2023, 03:46:31 am ---is this the correct way to configure JRVR to use a 3D LUT where I have 2 display modes

1) SDR : display targets REC709
2) HDR tonemapped to SDR : display targets DCI-P3 D65

using displaycal to generate the LUTs, see sdr_lut.png and sdr_jrvr.png for SDR + hdr_p3_lut.png & hdr_p3_jrvr.png for tonemapped HDR

I would then need to create 2 profiles to select between them using a rule like

SDR : IsEmpty[HDR Format])
HDR : !IsEmpty[HDR Format])

and I would need to make sure I've run video analysis on my entire library so the rule works correctly

for HDR, JRVR would then do the gamut conversion if necessary to DCI-P3 before the LUT is applied and output as SDR in a P3 container

correct?

mattkhan. Did you get this to work. I need to create two 3dlut profiles too. Any chance you could show your workings?

mattkhan:
it's basically as I wrote above, I have 4 profiles to select between all 4 combinations of HDR/SDR + 16:9/scope and which are based on the following 2 fields. This one is HDR 16:9

-[HDR Format]=[] [=[Compare([CropAR],<,2.2)]=1

CropAR is a custom field based on Video Crop

formatnumber(math(math(listitem([Video Crop],2,x) - listitem([Video Crop],0,x)) / math(listitem([Video Crop],3,x) - listitem([Video Crop],1,x))),2)

Thanks, Matt. Think I'm even more confused than before  :-[. I'll have a play and see if I can get my head round this.

Planned
- (Maybe) Dolby Vision Enhancement Layer support (for UltraHD Blu-ray discs) (under investigation)

Is there any news regarding full DV support?

Yesterday I got to watch Top Gun Maverick in mkv format with Dolby Vision, and my UltraHD Blu-ray discs couldn't stand the comparison :(
