about nvidia color settings and vlc

[dumbo4711]

hi sorry for creating a new thread,

but there were a few people who had problmes with too light colors in vlc with nvidia card
(i dont want to write in every thread i posted and bumping them up)


after some tests
i have to change my opinion about color settings

full dynamic range 0-255 can be recommended for ALL videos
(dynamic contrast enhancement & color enhancement should better stay disabled, looks better this way in my opinion)

Tools -> Preferences... (set Show Settings to All) and then choosing Video -> Output modules -> DirectX and disable Use hardware YUV -> RGB conversions
have the same effect, but like j-b said its slower
and some hd videos will stutter even on fast cpus despite cpu usage beeing only at 20% in fast dual core cpu with disabled conversion

its better to leave hardware YUV --> RGB active in vlc and change color settings in nvidia driver to full range 0-255


btw if u do screens with vlc
vlc is using full color range no matter if u use hardware conversion or not and no matter which nvidia setting is used

its darker but not too dark even in dark scenes details are ok
(screens from louis de funes - la grande vadrouille blu ray)

in fact, when disabling the Hardware YUV->RGB options VLC makes the right conversion, and with recent display drivers and this options set the conversion is correct too.

therefore the RBG value produced are the exactly values of the movie and respect it, indeed in my opinion it should not be changed.

If it seems too dark to you maybe it is because your screen is not well calibrated and you should change the constrast and brightness. there are tutorials that gives method to set a display so it gives correct colors.

here u can see the differences between limited and full color range

1.is 16 - 235 (wrong, looks a bit colourless, like a dust filter is active)
2.is 0 - 255 (correct settings, rich colours, but can be a bit dark in some scenes)






screens are taken with mpc hc standard render (not evr)
(vlc screens look always like 2nd picure no matter which nvidia setting )

yes second one is correct, otherwise a true black give the RBG value (16,16,16) which is a dark gray. this can be seen on the black area on the top.
you are right VLC is making its job in that case and now Nvidia is making it right too.
