The file is the original one unless the bd rip I downloaded got messed up. I dont see how it would cause a luma difference like that and IIRC, the PQ image were identical.
And even stranger, how can it just affect the Shield. And no we did not encode "something" else in resolve.
Of course it makes sense. The input was probably color managed in Resolve, making it tone map.
The metadata shows it: 1000 nits mastering, DCI-P3.

So the Shield apparently doesn't do well with tone mapping from 10k nits + BT.2020 in YCbCr, even with Dolby Vision.

The files only look similar with all planes combined. See single planes: https://slow.pics/c/ZoxjvanI
So what likely happened is that Resolve converted from 10k nits BT.2020 to 1000 nits DCI-P3.

Yeah, I know. Eventually I'll make a CM v4.x only file.

no, the Resolve encoded file is still 10 000nits.
As for the color management in resolve, you might be right.

"Apple devices always ignore L2 trim in profile 8.4 video. Actually there are two version of Apple’s profile 8.4, the early version is L1 only and old OS (like ios14) doesn’t handle trims at all (except profile 5). The recent version uses newer algorithm which needs L8 trim."
https://community.firecore.com/t/dolby- ... /19713/302
so do you see an L1 response with the 8.4 sample ?

@RESET_9999

I have a question regarding the x700: some mkv dolby vision movie files or mkv sdr movie files have dolby atmos dd+ 5.1 and the bluray player refuses to play the audio track. Using tsmuxer to convert those mkv files to .ts seems to solve the problem. Is that the right way to do it? Any drawbacks to picture or sound quality?

Just tried that bluray remux and no issue, so there might be something going on with your encode.

Code: Select all

1) Workflow.1= INJECT + AUTO-L5 + INJECT DV
2) Workflow.2= INJECT + MANUAL-L5 + INJECT DV
3) Workflow.3= INJECT + MANUAL-L5 + INJECT DV + TrueHD_to_TrueHD.ac3 + DDP_1536kbps
4) Workflow.4= INJECT + MANUAL-L5 + INJECT DV + TrueHD_to_TrueHD.ac3
5) Workflow.5= INJECT + MANUAL-L5 + INJECT DV + DDP_1536kbps
6) Workflow.6= Back to main menu

Choice? [1,2,3,4,5,6]?1

--input must be HDR10 MKV
--This workflow will measure HDR10, generate RPU, auto edit L5 and inject
--The black bars detection may not be perfectly accurate. It's maybe better to measure them manually

"Apple devices always ignore L2 trim in profile 8.4 video. Actually there are two version of Apple’s profile 8.4, the early version is L1 only and old OS (like ios14) doesn’t handle trims at all (except profile 5). The recent version uses newer algorithm which needs L8 trim."
https://community.firecore.com/t/dolby- ... /19713/302
so do you see an L1 response with the 8.4 sample ?
No, but maybe it's my TV, as it says here: https://community.firecore.com/t/dolby- ... /19713/306

I just downloaded the latest version tsmuxer (date: 25/02/2022) and when I add a movie file in it, it reports an error and doesn't show the dolby vision video track. Going back to a previous version of tsmuxer (date: 23/01/2022) and it works fine. Is there something wrong with the latest version of tsmuxer?

By the way, I just connected my external hdd to the x700 but it is not recognized. The external hdd is a usb 3.0 4TB WD hard drive. I read on Sony website that the max usb storage device size that the x700 can support is 4TB (GTP). I checked the hdd and its partition style is already GTP, so I'm not sure what's the problem here. I have another external hdd which is a usb 2.0 320GB Transcend hard drive and it is recognized immediately by the x700.

Throwing a guess out maybe the drive is ntfs and it needs to be exfat?

Both drives are ntfs. On Sony website it also says all formats (ntfs, fat32, exfat) are supported.

Try format using GPT with 2gb each partition. Worked at my Hisense TV. So 4TB you will have 3 partition minimal. 1 FAT for GPT (ill say may 200mb min, mine about 100gb for TEST DV ATMOS SURROUND HDR mp4 file etc.), 2 partition NTFS around less a bit than 2GB. Free Minitool Partition software recommended.
Sorry that was for internal android tv player.
For sony X700, i dont have. it may only seek first partition. https://www.sony-asia.com/electronics/s ... s/00013721
my bad. Try reducing little bit size of partition instead full 4tb, maybe could help.

I have been lurking this thread for a while and its has been an incredible source of information for me,
I do have one question...

If i have a Remux that has already been made from 2 sources(hybrid) Bluray and WEB DV5 converted to 8.1 and synced then injected to create the 8.1 with hdr fallback remux.....

if i wanted to encode that remux do i need to re-sysnc the RPU or will the extracted RPU already be synced, im assuming once the RPU is synced once and i extract it untouched it should then sync up with my encode flawlessly since the original remux i took it from was synced....

any help is appreciated..

If I have a profile 5 DV video with a 2.40:1 aspect ratio, is there any way to prevent the dark gray bars added by the x700 from changing brightness in response to the DV data? I don't think I'd mind the bars being dark gray by itself, but the flickering is distracting. (Short of reencoding the video to add black bars, that is. This is with TV-led DV on a C1.)
