What does this mean?

nice! looks like they updated the Dolby algo like in CM
great news thanks for sharing.

The only problem now remains is importing official scene cuts in DaVinci.

Also RESET should we now not use different scaling and 1080p resolution?

I guess scaling down with cubic won't be needed anymore.
Unfortunately, when you import the original XML, it doesn't import the scene cut but at least we can now do the dynamic L5 with the latest algo.


PS: I updated my resolve preset for 18.6 in the dovi_scripts tutorial folder.

Enough.. I don't give up on understanding more

Then your TV internal player is wrong.
It just make no sense that (2000 L1 + 1000nits BL) produce a brighter image than (1000 L1 + 1000 BL)

Is is normal that a higher luminance level on a “tonemaped under 700 nit tv” looks dimmer?, isn’t it?

I have a lg g3 here. I will replace it by a sony soon.

Anyways, I tried to play p7 dual layer ts via the media app on the g3 and they are not recognized. On my c1 they play as hdr, but on the g3 nothing.

I was wondering what lg did here.

I tried searching this mega thread but could find the info.

What is the purpose of reinjecting rpu from an resolve analysist? I see @RESET_9999 that you have done a lot of movie , what is the purpose of using your rpu ? What should i do with it and what would be the outcome difference versus original p7 DL?

Thanks

Yes, when the content exceeds your TV capabilities, Dolby dims the brightness to preserve highlights details. HDR10 also does that but with a static curve while DV does it shot by shot.

No P7 support since 2019 on LG TVs.

Resolve is for movies that come without DV or the ones that have static metadata.

18.6 also fixes the downscaling bug, now there is no longer a difference between the project set to 1080p or 2160p. NICE!

18.6 scaling VS no scaling:https://slow.pics/c/bJAeBXyi
18.5 scaling VS no scaling: https://slow.pics/c/4O89GXHw

But it's still important to have your project set to Custom Cubic because it's still the only algo that produces identical peaks as madVR.

EDIT: woah, scratch that. It turns out the scaling issues are caused by the cracked version .

What settings to use on cracked one?

I generated a xml using the recently updated preset in cracked version (18.6). Do we need to make any changes or is that fine?

“SEI Next-gen Box is equipped with Amlogic S905X5 which incorporates a New-gen CPU, 4K HDR UI GPU, NPU 2x4Kp60 decoder, and WVC. Incorporating Ai-SR, Dolby Laboratories Dolby Atmos, eARC, VRR, and QMS support”

Is there any legitimate other reason for dual 4k60 decoders other than FEL Dolby Vision? Sounds like an interesting contender

You have to use the same old settings cubic + 1080p as before...
This is so strange, I wonder if there are other things that don't work properly in the cracked version, I'm glad I legally bought it.

I personally gave up on those cheap android boxes but let us know if you try it.

wait I'm stupid sorry. When I tested my fresh install of resolve , the timeline was set automatically to 1080p and didn't change to 2160p when i imported the movie so that's why it didn't make difference in the metadata and scope when i switched from 1080p scaling to no scaling. When i redid the preset, i noticed that there was a difference between scaling or not like before so the behavior is still present and we still have to use he same cubic 1080p settings as before

With the new Tuning 1, there's a very small difference between scaling and no scaling: https://slow.pics/c/40L7cK3b
only with the old algo, there's a huge difference, same as before: https://slow.pics/c/YQEbjBIn

https://slow.pics/c/FXgydDrP

Pic 1 - 1080p Cubic 18.5 Resolve
Pic 2 - Cubic 18.6 Resolve
Pic 3 - 1080p Cubic 18.6 Resolve

Pic 2 and 3 are basically the same but I would choose 1080p cubic as it does speed up things for me.

Also RESET why is L1 of One Piece flat? Is it simply SDR?

EDIT - Here is my try of SDR to HDR conversion - https://drive.google.com/drive/folders/ ... sp=sharing

yeah, I hate it when the studios just put 100nits SDR into an HDR/DV container.
Basically, the only HDR in this TV show is the Netflix intro at 943nits and they didn't even bother doing the ending credits, it's just straight SDR text to HDR( blinding 10k nits) lol

About your conversion, I would have used the HDR webdl in Resolve but it looks like you went a bit too strong on the ''DARK'' setting. Personally I always reduce ''dark'' as much as I raise ''global'', otherwise, you introduce black crush.
example: https://slow.pics/c/i0IXZHzW

for reference, this is MA Theater Camp SDR to HDR I did recently (dark -0.30 /global +0.30):
https://slow.pics/c/pDBOKphG

I think they just want to make sure that the DV logo pops up, even if the content is just SDR. The Ahsoka show, Barbie are below 400nits most of the time.

Yeah my image looks too dark. I'll try some other settings. Thanks
