Thanks. How to use Resolve's scene cut detection in your scripts?

The script defaults to using internal/external scene cuts or madvr to generate them, so you will have to remove HDR10plus(2-2) to force madvr.
You could also use 6-2 to create the scene cuts. Rename the generated RPU the same as the mkv and run 3-1

What do you think about the Kodi app on android tv? I just installed the app on my Sony a95l and it seems to play all the Dolby Vision 4K remuxes smoothly. Might be a good option for those that can't get the Ugoos.

It's not going to support the FEL layer. So as long as that's not a concern, it'll probably "work" fine. Not really any different than the SHIELD.

May be a dumb question, but I've done a fair amount of research and still don't 100% understand.

In the Dolby Vision Stuff google sheet I see chart "ENCODER GROUPS TO AVOID BECAUSE THEY DONT ENCODE DV FEL PROPERLY"

I have a AM6B+ so I can playback DV Profile 7. I wanted to confirm that I understand encoding correctly. If the group that created an mkv left the file as a Profile 7 release instead of baking the FEL / encoding it into Profile 8, is no encoding actually occurring when the MKV is created from the original bluray disk files? Wouldn't this be a lossless packaging of the data directly into an MKV format?

For example, if a release is titled "███.2025.2160p.UHD.BluRay.REMUX.DV.P7.HDR.ENG.TrueHD.Atmos.7.1.H265-BEN.THE.MEN", does it matter that the release group is in the "avoid" list?

Mediainfo shows "HDR format : Dolby Vision, Version 1.0, Profile 7.6, dvhe.07.06, BL+EL+RPU, no metadata compression, Blu-ray compatible / SMPTE ST 2086, Version HDR10, HDR10 compatible"
if it's a remux, it should be fine...
That list is only for the encodes and that guy ben the men encodes are ridiculously bad: https://slow.pics/c/Yp0F0UWf
There's H265 in the title. Isn't that encoding?

H.265 usually indicates a remux or WEB-DL, while x265 typically refers to an encode, but not all release groups follow this naming convention.

Also if it doesn't specifically say 'remux' or 'untouched' it's usually an encode and you can double check the bitrate if they post it in the release, typically encodes usually gonna be ~24mbps or lower and remuxes like ~60+mbps or higher most of the time and also if it's a DV7 file then you can be pretty sure it's a remux

It's gonna say 'remux' most of the time though so just look for that

Hello! Just wondering if anyone could help me understand why this file isn't playing on LG CX internal player. Generated Dolby Vision with 3-1 option and converted audio to EAC3 with the tool as well, then muxed together in Tsmuxer. File seems fine in VLC player on PC, and the video only file seems to play fine as well in the LG CX internal player. But the final version isn't playing audio or video.

Get the ugoos, all the other devices drop frames with FEL playback. CPM A14 has perfect playback and doesn't really need any update so we are good forever...
I find PVR/TV playback has severe audio sync issues with the CPM build.

CPM was well into supporting more multi channel PCM formats that the current 2.0,3.1,5.1,7.1 limitation and improving audio synch when just disappeared 3 months ago. Hopefully CPM returns as A14 was a few features and bug fixes away form being great.

I have a rip from a 4K disc of mine which the Dolby Vision layers brightness pulses constantly (Its horrible) but a backup of the same disc using the same hardware works well. Does anyone know if this is likely a MakeMKV bug or UGoos AM6B software issue? The disc is slightly unusual in that it is Dolby Vision MEL with V4.0 Metadata.
