Dolby Vision now possible through MP4 Mux.

the dovi_baker output is 16bit RGB and contain 100% the 12bits essence. The dynamic metadata(tone mapping) is not applied by default.

Then you have to encode the 16bit RGB stream into a regular HDR10 10bit YUV stream with a P7 to P8 original RPU metadata.

my script does all of this automatically.

Thanks for the quick reply.
I looked at the dovi_baker GitHub, what kind of file do I get out of the process?
It mentions "baked into a PQ12 output stream"/"HDR PQ stream", what kind of stream is that and can Kodi play it back? What kind of picture mode will be signalled to the TV? DV or HDR?

Am I baking dynamic brightness and color data into the stream, that usually my TV would dynamically adjust on runtime like max brightness of the TV and will I therefore reduce the HDR quality on a future, possibly better TV?

There will be no SDR stream anymore, is this correct?
So I will have to be really certain that all of my devices support HDR or have HDR to SDR conversion.

Would you use this approach?

oh, I see. I thought you were talking about the cpm update.

Tested the DV full black video file. It was not black on my sony a95l. I had to go to 2-pt white balance setting of the tv and dial RGB-bias to minus 4 in order for it to become true black. If you know a better way using the Ugoos or dovi_script, kindly let me know.

Btw, with the latest A14 cpm build, what should I set L5, L6 and Restrict overlays to? They are currently set to Source, Source and Off respectively. I have watched a few films with subtitles and haven't seen any issues.

All normal then. LG TVs too, have raised black without the RGB trick. My C2 need -2 to get perfect black. My old C8, not even -6 worked, had to use contrast 49 IIRC.
if your TV has a semi-transparent mask for L5, you can leave it to ''source''. Thtas what I do on mine.

My LG G1 has no raised black with your test file when using brightness level 49. If going higher than 49 the blacks get raised.

Dont change the contrast/brightness; it affects the colors/hue. Instead, go in the white balance settings, set it to low 2pts, and decrease RGB until the glow is gone. My C2 needed -2 -2 -2

Will changing brightness just slightly from 50 to 49 have a big impact on the colors/hue?

Edit: had to set RGB to - 6 - 6 - 6 to get perfect blacks with brightness at level 50 instead of 49.

So this - 6 on all RGB channels is actually "better" than changing brightness from level 50 to level 49?
Can you explain this?

[RESET_9999]

I'm no expert about this but yes, it is better to change the white balance. Maybe @chros will chime in, he's the expert.

@daffie may be referring to these 'optimized settings' maintained by P40L0. I use these settings too. I haven't tested the validity of whether these settings are better, however, I have seen much community praise and endorsement for their settings, and it is frequently updated, so I trust it.

Yes, I am using the settings from P40L0 for my LG G1. I see he did some small new changes when looking at the corresponding file on Patriot. Colour was warm 50 but is now changed to warm 45 for example.

So I am a little in doubt if changing brightness from level 49 (P40L0 setting) to level 50 (standard setting) and instead doing -6 on all RGB channels is better in terms of overall quality on Dolby Vision content. Hope @chros can say something about this?

@RESET_9999 do you really go with your nose up on the screen to test the brightness with that video - or do you test it by sitting at your regular seating position?
When going with my nose up the screen I have to set the RGB levels a little lower obviously.. (-6) That is why I am asking. Thanks!

I don't have to guess my settings based on some website or guy. I paid big money to have my C2 professionally calibrated and there is no setting such as ''screen brightness'' in my DV filmmaker mode.
You told me in a private message that you were using the ''cinema home'' mode, so right away, this is wrong, and this mode is inaccurate. Also, warm 50 is the accurate setting, not 45.

As for the raised black fix through the white balance, I know and trust @chros more than anyone.

You have a C2 I have a G1. Some things are different. I don't have a filmmaker mode for DV. I have a ''Cinema'' and ''Cinema Home'' mode for DV.
These settings from P40L0 are not just some ''settings from a random guy on the internet''. As told already by another user above, they are pretty well regarded as very good all round settings for NON CALIBRATED displays.

Of course when you have your screen calibrated it is not good to take over someone his settings. I understand that.

I changed ''Cinema'' mode to brightness at 50 + RGB white point -5. Will watch some movies like that and see if I notice a difference.
I noticed immediately that ''Cinema'' mode is darker compared to ''Cinema Home''.

For testing the full black screen video - do you judge it really close up or just by sitting at your regular seating position??

Thanks again!

[RESET_9999]

It's not the cinema that is darker, it's the ''home'' mode that is brighter (overtrack) and inaccurate.

Well, if he recommends warm45 and the ''home'' mode, I'm not sure about that.

it doesn't matter, my C2 is in a pitch black room with black velvet on the floor, walls, and ceiling and I have 20/20 vision. Whether I'm 6 inches from the screen or in my normal sitting viewing, there is no raised black visible with -2-2-2.

Just want to add my 2 cents, having seen that spreadsheet over the years from time to time, it always had several flaws, and honestly just looks detailed and "nerdy", so everyone started supporting, upvoting and sharing it, and consumers have always liked being told what "settings" they should have, be it from rtings.com or this guy. Perhaps it's not downright terrible, and has some sensible advice for games console users, but the guy is absolutely picking some values and settings out of thin air and purely based on his personal preference (for brighter/saturated, but inaccurate picture), e.g. color depth 55, warm 45, black level at 49, or turning on dynamic tone mapping for HDR mode(!), being glaring examples. I get he invested a lot of time into his videos and updated spreadsheets etc. but he has a major financial incentive given his Patreon subscriptions and obviously his popularity. However, I doubt he has owned all of the LG models from 2020 to now or has any real professional calibration background (this is obvious from some of the settings he recommends honestly). I also don't understand why he provides blanket settings for all LG models by year rather than series (i.e. B, C, G), as this is a big red flag oversimplification, in my opinion. Oh, and one last thing, he seems to now be selling HDR "optimized" settings for specific video game titles on his Patreon, which is egregious!

I would strongly recommend you find calibration patterns, video files and guides and invest some time in calibrating/optimizing your own display, this should yield much better results in SDR/HDR/DV modes, compared to blindly following any spreadsheets or settings found anywhere online. Here is a great place to start for HDR calibration: https://www.avsforum.com/threads/hdr10- ... t.2943380/

you dont do your own calibration?

[RESET_9999]

No, I don't have the equipment, and calibration is not something I'm interested in learning anyway, so it's just simpler to pay someone.

[SamuriHL]

There's too much panel variation to trust someone else's settings. Chros will likely tell you the same and that what works on one panel may be different on another. You basically have to use a black pattern and adjust it until you can no longer see brightness in a pitch black room.

As has been mentioned already, calibration is always the recommended way to go. Yes it's expensive to either get equipment to do it yourself or to hire someone, but the end result is worth it. If you're expecting to see all the fine details of Dolby vision with full FEL you really want your panel as accurate as possible.

yeah absolutely. I dont understand people that buy expensive TVs but don't calibrate.
Speaking of expensive TVs, it looks like the G5 is a DV killer for most content. 2500nits 10% and 360nits 100%
I'm going to try to sell my C2 lol.
