Sane settings for Macbook M3 display (gpu-next)

[Foul-Tarnished]

Hi, I'm new to mpv and wondering what sane settings I could use on a M3 macbook display (DCI-P3 HDR)

So far here's my mpv.conf (tbf I'm not sure about the tone-mapping to use for SDR->HDR, if I should use one at all)

vo=gpu-next
profile=gpu-hq
gpu-context=macvk
macos-force-dedicated-gpu=yes
hwdec=videotoolbox,auto
hdr-compute-peak=yes

icc-profile-auto=no
target-colorspace-hint=yes
target-prim=apple
target-trc=hlg
cocoa-cb-output-csp=display-p3-hlg

libplacebo-opts=preset=high_quality,downscaler=lanczos,peak_detection_preset=high_quality,color_map_preset=high_quality,lut3d_tricubic=yes,tone_mapping=auto

Disabling icc-profile seems to make the image darker (for SDR content)
I know ICC is not used for HDR, but it is for SDR even when tone-mapping is used ?

[Akemi]

if you deactivate icc profile usage, icc-profile-auto=no, it will never be used.

the icc profile is unrelated to the tone-mapping in the broader sense. though the target-colorspace-hint=yes is mutual exclusive with any kind of icc profile usage.

It seems MPV is more blue (and brighter) than IINA (without ICC, with auto tone-mapping) for SDR content

MPV (right) is brighter, even if it's not the case in the screenshot...?

[Akemi]

if you use target-colorspace-hint=yes you basically tell macOS you want to render brighter than SDR (eg what apple calls EDR). so it can be brighter than iina if it doesn't tell macOS the same.

sure it will look different with different settings. also mpv uses gpu-next and inna libmp (which is the older gpu).

I can't speak to anything macos specific, but generally you should never use --libplacebo-opts for your day-to-day config unless you know what you're doing, since it will override mpv's options and can create unexpected behaviors.

[Akemi]

macos-force-dedicated-gpu=yes doesn't make any sense. first of all no ARM based mac has a dedicated GPU. it can only use the one on the SoC. also that option doesn't do anything on macvk.

hwdec=videotoolbox,auto use it only if you really need it. it might make quality worse. also auto should be enough, or auto-copy if you need CPU based filtering.

hdr-compute-peak=yes just keep it on default auto.

icc-profile-auto=no i would activate that one atm for SDR sources. especially if you have a icc profile from properly calibrating your display(s).

target-colorspace-hint=yes activate it for none SDR sources only.

target-prim=apple target-trc=hlg those shouldn't be needed by default. apple rbg as prim seems to completely off tbh.

cocoa-cb-output-csp=display-p3-hlg no idea what you expect this option to do. but this is a cocoia-cb only option you are not using cocoa-cb but the macvk vulkan backend.

libplacebo-opts=preset=high_quality,downscaler=lanczos,peak_detection_preset=high_quality,color_map_preset=high_quality,lut3d_tricubic=yes,tone_mapping=auto scrap those.

tbf I'm not sure about the tone-mapping to use for SDR->HDR

i don't recommend inverse tone-mapping, if you don't purposely want this effect.

in the end you should use settings you like, or if you a 'pedantic' you should know what you are doing and want.

Thanks for the help

Shouldn't videotoolbox reduce power usage ? quite important for a laptop (even though the battery life is insanely long on these)

Apparently DCI-P3 HLG was done by apple, any idea what does it do ? it seems to change the colors
I can see "Pure power curve (gamma 1.8), also used for Apple RGB" in the doc, so not sure what target-trc to use, hlg look good so far

Is there an equivalent of "cocoa-cb-output-csp" for macvk ?
Just want to make sure my DCI-P3 display is fully used

for "target-colorspace-hint", I'm not sure to understand what you mean, what I should set it to
I can make a "smart" conf that only apply certain settings to SDR and others to HDR ? hmm

Lastly should I use target-prim=apple or dci-p3 ?

[Akemi]

1. like i said. use hwdec when you need it. if your macbook is plugged in, i would say power usage is not a concern.
2. i am not sure what you are asking. it's a colour space defined as dci p3 colour space with a HLG transfer (on a side note Apple is using display p3 not dci, it's a bit different). either use what you like or leave it as is.
3. target-colorspace-hint=yes is the equivalent of cocoa-cb-output-csp, just automatically. it tells macOS which colour space the mpv window is in (what we render to) and the macOS compositor does the rest of the colour transfers to the colour space/characteristics of the display (eg what is set in system settings as colour profile). with that being said theoretically it's the best to set target-prim and target-trc to something closest to your display characteristics, since that defines what the target-colorspace-hint on the window is set to.
4. yeah you can make a 'smart config' with auto profiles. as an example to only activate certain options on HDR material. though i am not sure if checkin video-out-params/max-luma>203 to check for HDR sources is the best way.

[HDR]
profile-desc="Enables on HDR sources"
profile-cond=p["video-out-params/max-luma"] > 203
profile-restore=copy
target-colorspace-hint=yes

5. if you want to set either of them, don't use apple. though maybe bt.2020 + pq/hlg would be better. personally i left it unset for now and let the automatic do it. though i still need to find the right settings myself.

I couldn't get HDR content to look right on an M1 MacBook Pro (either it wouldn't work or the colors would be hyper-saturated). After trying different things, this seems to do the trick, although I'm a bit confused, in the documentation display-p3 is not listed as an option for target-prim.
Would appreciate it if someone can replicate or clarify !

vo=gpu-next
profile=high-quality
gpu-context=macvk
target-colorspace-hint=yes
target-prim=display-p3
target-trc=hlg
