In fact maybe I always make my videos and I exported them with a bit too much brightness and if I use Kodi with Shield I can't lower the brightness because it is already at minimum. I should lower it slightly, maybe a further - 1 or -2, but I can't do it.(2020-04-12, 12:53)FoxADRIANO Wrote:(2020-04-12, 12:36)noggin Wrote: OK - you are using HDMI input 3. That will probably (*) have it's own SDR and HDR picture settings just for that input, which are not related to the picture settings of the other inputs, your DVB TV tuner, or any Android TV apps etc.
The important thing is to go through all the settings and disable all the nasty processing etc.
Test images are test sequences that you use to adjust brightness, contrast, black level, gamma, saturation (aka colour) etc. to ensure that your TV is displaying pictures correctly. Without them you are just 'adjusting by eye' which is never a great idea.
I'd suggest reading up a bit on TV calibration and set-up to get a better understanding as to how you should configure your display to be as neutral as possible (so that you see the material you have shot, edited and graded as accurately as possible)
Ah - 'like' is always dangerous. If you are watching material you edited yourself, then you want that displayed as correctly as possible (if you don't like 'the look' of your material, you can then alter the way you edit and grade it)
Kodi shouldn't require any calibration - that's only really needed for 'edge case' examples (where there are known issues you need to compensate for). It may require some set-up - but not calibration.
Your Shield TV has a number of options for output - and they can interact with Kodi.
Do you watch any Rec 2020 material - or is all your material you watch Rec 709?
Yes - the sliders will be different for every source. I said that in my earlier post :
Thanks for your very good reply.
I use a camera to take videos. I use Lumix GH5 and I think it rec. in Rec 709. Anyway I put these settings in the Menu: 4K 8bit 150M 50p.
Yes - chances are you are shooting Rec 709 3840x2160p50 8-bit in either 4:2:2 or 4:2:0. I assume you then take this material into FCPX, Prem Pro, Avid Media Composer or Davinci Resolve and make sure it is also seen as Rec 709 in those packages for grading?
Then you export as a 3840x2160p50 8-bit Rec 709 4:2:0 h.264/AVC or h.265/HEVC file to play on the Nvidia Shield TV?
If so I'd ensure the Nvidia Shield TV is configured for Rec 709 output in its HDMI settings, and unless you also use the Shield to watch other video material (Netflix, Amazon Prime, Disney+ etc.) that is Rec 2020, I'd also probably disable colour gamut switching.
If I use Kodi with Sony TV, I can I can further lower the brightness and I watch it fine (brightness and colours), but the video isn't absolutely fluid. If I watch the same video with the software of Sony TV, what's there by default, I can watch it fine. I can't use 150mb with Kodi and Sony TV. I only have to use 100mb. What a pity!
You can tell me to chance software (Kodi) but I can't because I need they must be in line as in the photo I attach:
