Disney+ HDR/DV Hybrid DL option

Ragnarocek

Hello,
I have the information, that Disney+ is starting to offer HDR/DV hybrids (same as HBO, if the title is available in hdr and dv, by selecting the hdr option you will get the hybrid). Example title is Daredevil: Born Again S02 E05 (this one I have confirmed).
Can we get the possibility to download this hybrid versions same as from HBO ?

Thanks

I was wondering how they have been doing it in the scene. Have they been tinkering with both streams or had they done something like this all along?

Best practices is to download both HDR and DV stream and then injecting DV to HDR file using DoVi Scripts… Its easy, but time consuming (u must dl both of the streams). I’m doing it at regular basis…

Ragnarocek I tried and failed miserably trying to do this with Black Widow the other night, Gemini didn’t tell me you needed both. Is there a guide or resource you can recommend? How does one view the actual bit rates on Disney Plus, not on the download screen.

Hulu has always been that hybrid by default. Disney would have to re process titles, all there 4k ones so even if it does come it would have already been processed and set to be rolled out or it’s mixed up with Hulu content. Also if it’s added to Hulu they will re-process it. Hulu and Disney share playlist information from the same sever.

Just for info:-

if your hardware can work with ITP colour space of DoVi, don’t do yourself the disservice of “degrading” down to BT.2020

Funny how people obsess over audio bitrates that, for most part, make no difference to the ear, yet deliberately choose worse visuals 🤷‍♂️

Either D+ are changing things on their end, or SF’s track selection algo is too naïve, this is what I get downloaded with 7024 when I select HDR for Maul:-

S01E01_Chapter 1_ The Dark Revenge:- HEVC, HDR: Dolby Vision / SMPTE ST 2094 App 4
S01E02_Chapter 2_ Sinister Schemes:- HEVC, HDR: SMPTE ST 2086
S01E03_Chapter 3_ Whispers in the Unknown:- HEVC, HDR: Dolby Vision / SMPTE ST 2094 App 4
S01E04_Chapter 4_ Pride and Vengeance:- HEVC, HDR: SMPTE ST 2086
S01E05_Chapter 5_ Inquisition:- HEVC, HDR: SMPTE ST 2086
S01E06_Chapter 6_ Night of the Hunted:- HEVC, HDR: SMPTE ST 2086
S01E07_Chapter 7_ Call to Oblivion:- HEVC, HDR: SMPTE ST 2086
S01E08_Chapter 8_ The Creeping Fear:- HEVC, HDR: Dolby Vision / SMPTE ST 2094 App 4
S01E09_Chapter 9_ Strange Allies:- HEVC, HDR: SMPTE ST 2086
S01E10_Chapter 10_ The Dark Lord:- HEVC, HDR: Dolby Vision / SMPTE ST 2094 App 4
was expecting exactly 1 for move_list.count, got 2: 6x HDR10, 4x HDR10+ w/DoVi

So it seems that SF can download hybrid, but we need to know what stream is what…

Tried the first two “bitrates” (they’re fake tho, there are peak br instead of content br in the list)…

First one:
Video
ID : 1
Format : HEVC
Format/Info : High Efficiency Video Coding
Format profile : Main 10@L5@High
HDR format : Dolby Vision, Version 1.0, Profile 8.1, dvhe.08.06, BL+RPU, no metadata compression, HDR10 compatible / SMPTE ST 2094 App 4, Version HDR10+ Profile A, HDR10+ Profile A compatible
Codec ID : V_MPEGH/ISO/HEVC
Duration : 48 min 3 s
Bit rate : 13.8 Mb/s
Width : 3 840 pixels
Height : 2 160 pixels

Second one:
Video
ID : 1
Format : HEVC
Format/Info : High Efficiency Video Coding
Format profile : Main 10@L5@High
HDR format : SMPTE ST 2086, HDR10 compatible
Codec ID : V_MPEGH/ISO/HEVC
Duration : 48 min 3 s
Bit rate : 13.8 Mb/s
Width : 3 840 pixels
Height : 2 160 pixels

I would like to ask the devs to enhance video download selection list with information abut the stream….

@Wilson.Wang can you please hand off this to the devs ?

Thank you.

Wilson.Wang

I will ask the dev to check it.

May be Disney+ upgrade something…

Not all titles are available as the hybrid… That is why I’m calling for clear list of video stream list in the SF, so you can indentify if the stream is HDR, DV or the hybrid…
