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.
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 :P

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

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.

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.
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?

Inception 2010 BD Generated T3 (MANUAL TRIMS).bin

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!

I'm surprised they didn't rename your ''cinema'' picture mode to ''filmmaker'' as they did on the 2022 series with the latest update. Do you have the latest firmware?
The ''cinema home'' vs ''cinema'' modes were confusing, and ''filmmaker'' name makes much more sense IMO.

Yes mate, latest firmware. Still received an update just a week ago actually.
In HDR mode there is a filmmaker mode, but not in Dovi.
Doesnt matter, it's just a fancy name. On the G1 Cinema = filmmaker mode on the C/G2.

I would only use the Cinema Home mode in the future for very dark movies. And per skull88 suggestion I lowered peak panel brightness from high to medium in the Cinema Home mode.

I'm running dovi_scripts right now. Somehow it's editing L6 by itself?

I never understood why the generated L2 trims in the cmv4.0 workflow were raising the low-nits scene brightness, but I think I know why now. I think it's Dolby workaround for fixing the crushed black issues with cmv2.9 content/hardware. The generated trims dont fix the black crush completely, but it improves it a lot and makes it look almost as good as cmv4.0.

L1 + generated L2 cmv2.9 4000nits RPU ... crushed around 68 https://drive.google.com/file/d/1TxInjm ... drive_link
L1 cmv2.9 no trims 4000nits RPU... crushed 76 https://drive.google.com/file/d/1RlG9T5 ... drive_link
L1 cmv4.0 4000nits RPU ... no crush at all 65 visible https://drive.google.com/file/d/16n7hTZ ... drive_link

I'm confused, genuinely as I don't know if this is a specific topic for something or if there is something to learn.

I've always used makemkv for movies so far, and have always had DoVi and Atmos support withing the mkv container and just Jellyfin on Shield. Using a Hisense w/ eArc.

Is there something I should be aware of in the future when I want to upgrade to an LG or similar? Seems from the comments the answer is yes.

Or is this about reducing the disc size down and maintaining it? :?
