Other than the possibility of a higher spec cable these are a few of my current conclusions for running Coreelec on my old Beelink Mini MX S905 rev b, 10bit files playing fine.
Coreelec Settings:
Disable noise reduction (may help reduce CPU load but certainly not needed on most TV’s)
Deinterlancing is on but probably not required for most files so not an issue (I think most TV’s will do this anyway).
Limit colour depth is left on 10bit as doesn’t seem to cause issues with the box.
Not using 4-2-2 colour as causes judder and deep colour seems to be lost.
LG LCD TV:
I turned off ‘True Cinema’ (24p) on my oldish LG LCD doesn’t seem to do much and a few things I read suggest it’s actually forcing 24p into 60hz with some kind of pull-down but not sure about that. TruMotion is off as it’s good on some stuff but really distracting on other content.
So I still notice micro-judder from HEVC but true frame-drops seem to be rare although can’t be sure. Isn’t there a stats overlay that show video info built into Kodi? Not planning on spending hours waiting for frame-drops but they are seen within seconds on action scenes anyway.
So as said I may try a higher spec cable, certainly not more than £10, and then settle with the way things are. Sometimes the artefacts from over compression just have to be accepted.
EDIT: Turned noise reduction back on as it doesn’t seem to make any difference. More importantly turned ‘Real Cinema’ back on (LG 24p mode) as the constant micro judder seems to have been caused by having it off! Normally the judder from 23.976fps is every minute or so but what I was experiencing was a constant micro judder which I thought was poor encoding as it’s subtle. Still not sure it’s helping but!!! Yes fricking nightmare when you start looking for improvements as you become more focused on any slight glitch.
Is it encoding, hardware or just all in the mind???
