What is the best luma and chroma upscaling method for MPV in 2022?

[laichiaheng]

Hi, I have a question, what is the best luma and chroma upscaling method for MPV player in 2022? As I remember, the best Chroma upscaling method was KrigBilateral.glsl shader? The best Luma upscaling method was FSRCNNX shader, am I correct? What is the best upscaling suggestion in 2022?

"best" is subjective

@CounterPillow But there must be some way to see them, right?

Nothing better has been invented yet. Maybe in the future when everyone will be running tensor cores.

But there must be some way to see them, right?

Yes, use PieAPP, objectively the best metric. Btw, see the latest comments for adaptive-sharpen, where PieAPP was used for evaluation.

The so-called “best” cannot match everyone’s preference.

Just use KrigBilateral(for chroma) and trust in igv!!!

Okay, for those who don't want to bother reading themselves, according to the comments linked above, the best™ method is:

FSRCNNX+dscale-lanczos+AS-0_1-luma-2022-05

Which I assume from the context is:

• FSRCNNX (variant/version not further specified here)
• --dscale=lanczos
• AdaptiveSharpen, luma only version, update from May 2022 (I assume that's the one from the linked gist, albeit this being the RGB one?)

EDIT: latest AdaptiveSharpen revision supports LUMA
