Dolby Vision now possible through MP4 Mux.

I noticed immediately that ''Cinema'' mode is darker compared to ''Cinema Home''.

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

As told already by another user above, they are pretty well regarded

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

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

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.

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

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.

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/

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 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.

I get that - just funny you reauthor your own DV yourself cause don't like what they do there but trust someone else to calibrate your tv lol

I do my own calibration but also I don't have expensive TVs/monitors and pros probably (definitely) have better tools than me (I just use some 3000nit colorimeter and calman) - for me it's just part of the HT/HTPC hobby understanding/performing the calibration myself

[RESET_9999]

Haha I know, and not only do I generate my own DV Level 1 metadata, but I now also do manual shot-by-shot trims for my favorite movies. I just did Interstellar.
My calib guy is very knowledgeable, though. He did all my TV and projector for the past 15-20 years, I trust him 100% and he has an expensive meter+pattern generator.

I'll buy the G5 as soon as it's available in Canada, so I might give it a go. We have a cheap i1display pro where I work, and I have Raspberry Pi with PGEN somewhere in my house.

Holy hell. They're trying to get me to upgrade my g2 I see. But not right now. Still tempting though!

Recently, I've noticed that for every movie I play on the Ugoos, the first few seconds are just a black screen and the last few seconds are a frozen frame (I can still hear the audio). I tried playing the same movies on my PC and there was no issue, so the culprit might be cpm A14.Has anyone else experienced the same thing?

@RESET9999

For some movies that only have hdr10 in bluray version, when I look at your rpu folder, I see multiple rpu files; some of them are .bin, some are .xml. For example, Avengers End Game have 3 rpu files:

-Avengers.Endgame.2019.IMAX.PRORES_MASTER P5 to P8.bin
-Avengers.Endgame.2019.BD_P5 to P8.bin
-Avengers.Endgame.2019.BD_Generated OSC T3 (best version).xml

Is the best version cmv4.0 and are the other two cmv2.9? Should I always use the best version then?
And based on your grademaster check, for this film, it is not certain that injecting DV into the bluray version will work? How do I know that it's not working?

I've seen MANUAL TRIMS in your RPU folder a few times now. I don't think I understand what it means... Are you making your own artistic trims?

The best version of this movie would be the imax prores version but the guy who did it apparently doesn't know what he's doing and there are many glitches in it. I reported it on BHD but he never repacked or even responded. The web-dl measurement looks brighter than the BD, so the safest version is my generated RPU. Not to mention the framestor remux rpu is out of sync.

XML is the same as bin, XML just takes less space on my GD.

Yes, I do trim for my favorite movies. I monitor the 600nits extrapolation shot by shot and do a 100nits trims when the content is brighter than 600nits. I adjust the darker area of the shot, I restore the crushed details. I still have to watch the whole movies I did, but in the sample I previewed, it works very well, at least with my C2 810nits target... The real test would be to watch on a low nits projector.

Also, I use the offset control (positive lift), so my trim will only work properly on devices that support it, like the ugoos A14+ or TVs internal players. I also add a blank 1000nits trims, which cancel the trims effect on TV brighter than 1000nits.

Big thanks to RESET_9999 and skull88 for the suggestions about the best (=most accurate) picture settings for DoVi on my LG G1.
I have to agree that Cinema Home is too bright, thanks for pointing me in the right direction!
