Hi!
I assume that the original was a full 1280x720 444 master. When upscaled to 1080p the chroma was downs caled to 540 (using bicubic kernel). Why are you using "spline64",invks=true? Chroma was downscaled in this case.
I prefer encode to device, so that's why i prefer the output to 1080 (i don't trust on tv upscaler), so i'm using this:
Dither_convert_8_to_16()
debicubic(1280,720,lsb_inout=true)
nnedi3_resize16(1920,1080,lsb_in=true,lsb=true)
ditherpost()
(Converting to 720p 444 is a valid choice) But in the end TVs and player renderer will perform some upscaling (MadVR is not always a choice).
How can i mask / copy the 1080 post effects to my nnedi output (computers screen text seems to be 1080 added on post production). I know DebilinearM
is for that but i need an example.

But, if they use a 1080p 4:2:0 8bit source and encode in 1080p 4:4:4, then they are just upscaling chroma, which doesn't make sense.

Yes, but some groups are doing that, so i was thinking that maybe there was a reason (a new "magical" chroma upscaler or something like that).
One more thing: I have Toradora BD and DVD (both from japan) the BD upscale was a little dissapointing to me. So i was thinking on trying DebilinearM - nnedi3,
or shoul i use nnedi3 on the DVD?
Advice?
Thanks!
