JRVR Feature request - Native colorspace playback option

(1/6) > >>

afss_br:
Hello, I have a JVC projector which allows me to manually chose BT.2020 or BT.709 as source signal colorspace. I noticed when there is a colorspace conversion being done by the media player there color errors (sometimes oversaturated and sometimes washed out).

For instance, if I define JRiver output as BT.2020 and the source file being played is BT.709, there is a forced BT.709 to BT.2020 conversion going on that messes up colors on my display (with the proper BT.2020 selection). Comparing the native BT.709 souce with a matched display BT.709 setup, I get much better results.

Please would you consider creating an option within the JRVR/Output/Calibration/Screen Gamut dropdown menu for NATIVE (the current options are Auto, BT.709, BT.2020 SMPTE, PAL, DCI-P3). In other words, what I am proposing is for the output signal colorspace to just match the source material colorspace. I would still like all HDR Tone Mapping capabilities to take place with BT.2020, but WITHOUT colorspace conversions if the source file is BT.709 (not HDR).

What HDR content do you have that is in rec709?

Something is wrong somewhere though as converting rec709 to bt2020 shouldn't look strange (doesn't here, also with a JVC projector)

Hendrik:
Since JRVR is not capable of communicating which colorspace is being used to your display, this mode would result in bad output unless you manually intervene everytime you start a new file - which is anything but comfortable.

If you really want something like this, thats what profiles are for. You can make one based on the video gamut and then adjust the output gamut accordingly.

jmone:
Matt is right, 709 should look fine in 2020.  I also have a JVC, but will need to check.  If (for whatever reason) you do want to do the manual swap at the JVC end, Hendrik is also right in that you can setup Profiles for all sorts of combos including Colour Space (which is the name of the field in MC for this).  You can do the same for Interlaced, various resolutions etc etc.  Profiles are very powerful for those that want to dial in settings for various attributes.

mattkhan:
if you do want to use profiles, the jrvr specific fields are listed in https://yabb.jriver.com/interact/index.php/topic,133480.msg924609.html#msg924609 otherwise make sure you run video analysis and then use the fields that produces
