New owner here and i would like some help. When playing back HDR content output is at 8bit instead of 10 bit. The tv goes into HDR mode but is in 8bits. I tried this command
I’m a new happy owner of an Vero 4K. Is there a chance to downscale 4k output to the following parameter:
4k24p hdr 420 10bit?
the situation is as follow:
I have a projector (Sony VW320ES) which is 4K HDR capable at 24p but only with Chroma Subsampling to 422 or 420…
Vero 4K is playing all Videos in 444 hdr 8bit. Only when I put a HDFURY Linker between Vero and Projector I get it running in 10Bit Mode after I added the follwing command:
This would suggest something in the HDMI chain does not support this format.
Have you tried a direct connection to the projector? If this works then we should check EDID when connected to other intermediary devices.
I‘ll check but is there also a chance to keep it running in this mode constantnly sonthat I don‘t need tonuse the command line?
But as I wrote before, when HDFURY Linker is doing the Chrome Subsampling to 422, the Veronis switching correctly to 10bit. I only want that 4K HDR Videos switch correctly into 10 Bit Mode
Yes – if you set it in rc.local it’s permanent, what have you tried currently?
Are you saying that you would only like HDR10 content to change to BT2020 and everything else to stay as 8-bit Rec709? This has already been requested by another user and is being worked on.
I wrote 10 or 12 bits because i dont know the highest bit depth vero 4k can upsample. Everything should be played back according to the source’s colorspace. No conversion. Except for when a BT.2020 video is playing and the tv/projector/display cant handle hdr and the player needs to convert to sdr. The gui can be in 1080p bt.709 60hz 8 bit. If it can go up to 10 bit or 12 bit ( still 1080p bt.709) without messing the table i posted above is an added bonus. Less banding.
Then an option should be made available in the menu.
Color depth option: Auto, 8bit, 10 bit, 12 bit ( if available)
Chroma upsampling: Auto, YCbCr 4:2:2 , YCbCr 4:4:4
Auto should work as the table in my previous post( or for the max available options through display EDID)
10 bit should be the minimum for HDR BT.2020 content and 8 bit for SDR Bt.709. Having 10 bit enabled should not activate BT.2020 signaling if a bt.709 file is playing whether is 1080p or 2160p. Colorspaces should remain intact.
Well Sam should answer that i guess and confirm if such a configuration is possible . I know kodi has a lot of limitations but that is how all video players should handle video for accurate playback. Like my previous post.
Currently there should be no negative effect of 10-bit Rec2020 being sent for all content. Others haven’t reported this issue so I am not sure why you only discovered it recently.
It should be possible to only switch modes when needed. It may not always be useful to have a long list of options as only some options are available at specific Refresh Rates. Perhaps an HDR ON/OFF option is all we need, with robust logic on how to handle different types of video
There is a negative effect that i tried to demonstrate with the samples i sent you. If you force bt.2020 and the source is bt.709 the colors are all wrong. I dont know what equipment other people and/or if they are playing this kind of content. Changing colorspaces when there is no need to i think is wrong.
Most of the users have normal TV‘s which are completely capable of 4k60p 12bit HDR with max brandwidth…
At currently available projectors it‘s different. To have them capable for max brandwitdth you need to buy a projector for minimum 14500€…
The other native 4k projectors are only capable as I mentioned above… Same for the e-shift projectors. for both versions the hdmi port have brandwidth limitations…
But is this workable or a release is in nesr future for a test version?
The colour space shouldn’t actually be changed here.
I understand that this is problematic for you though. We can definitely work on a solution for this.
This could probably land in late January for testing.
