Make that 10 000.

Great, thanks - just checking I got it right!

Wow, this HDR10+ -> DV stuff seems pretty amazing It seems to work on Amazons streaming content as well, based on a quick test. However i don't currently have anything i really want to watch through to check, but i'll definitely put some new episodes of The Expanse through this procedure when they arrive (december i believe)

You need to demux the video first, and then run the script on the HEVC file.
example: python hdr10plus_remove.py -i video.hevc -o processed_file.hevc

Thanks for that. Is there an idiots guide on HDR10+ to DV conversion?

I wrote up how this idiot does it here:

I looked at the guide on avsforum but I am having a little trouble with the installing from the Dolby labs GitHub do you think you could explain the installation process or know of some clear documentation or video that can help? I got as far as devenv mp4muxer_2010.sln /Rebuild but I got 2 errors one of which is a fatal one and I am not even sure I am doing it right in the first place.

error 1: 1>..\..\..\src\mp4_muxer.c : error C4335: Mac file format detected: please convert the source file to either DOS or UNIX format

Hello All,

i would like to reduce dolvby vision (profile 5) mp4 file from 9GB to ~3GB by re-encode video in Staxrip.
My file mediainfo looks like below:

Video
ID : 1
Format : HEVC
Format/Info : High Efficiency Video Coding
Format profile : Main 10@L5.2@Main
HDR format : Dolby Vision, Version 1.0, dvhe.05.06, BL+RPU
Codec ID : dvhe
Codec ID/Info : High Efficiency Video Coding with Dolby Vision
Duration : 25 min 4 s
Bit rate : 22.4 Mb/s
Width : 3 840 pixels
Height : 2 160 pixels
Display aspect ratio : 16:9
Frame rate mode : Constant
Frame rate : 23.976 (24000/1001) FPS
Color space : YUV

Tagged date : UTC 2021-06-18 06:43:27
Color range : Full
Codec configuration box : hvcC+dvcC

what i did to reduce video file size is:
1) extra DV profile 5 by this command:
ffmpeg.exe -i DV_TEST.mp4 -c:v copy -vbsf hevc_mp4toannexb -f hevc - | dovi_tool.exe extract-rpu - -o RPU.bin

2) Setup StaxRip x265 encoder with Profile 5 and path to RPU.bin

3) After re-encode is done i mux hevc to mp4 by executing this command:
mp4muxer.exe --dv-profile 5 --input-file DV_TEST.mp4 --output-file mp4muxer_out.mp4

4) Add audio.eac3 and subtitles are done by this command:

mp4box.exe -add mp4muxer_out.mp4 -add audio.eac3 mp4box_out.mp4

and i got file like below:

Video

but when i try play it on my LG oled 55b7v TV from usb drive dolby vision is recognized but when try to move forward it stops play this file and start plays next one.

Could someone guide me where is the problem?

Dolby provides binaries: https://github.com/DolbyLaboratories/dl ... master/bin

I have a question regarding encoding a file to 1920x1080p and add the Dolby Vision later. Somehow, I don't get the right file after RPU insertion.

I have encoded a Game of Thrones Episode (4K REMUX, which is Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU). I encoded it without cropping, (which I do for every encode, also movies, I just resize it from 3840x2160 to 1920x1080).

It got me an 1080p episode, which is HDR10. I used the following command to change the .mkv file to hevc:

ffmpeg -y -i GOT.S01E01.mkv -an -c:v copy -f hevc GOT.S01E01.hevc

After this, I use the command to extract the RPU from the HEVC with mode 2:

dovi_tool -m 2 extract-rpu GOT.S01E01.hevc, which gives me an RPU.bin, which, I think should be converted to profile 8.

After this, I use the ffmpeg command to change the re-encoded file from .mkv file to hevc.file. I then usethe following command to inject the RPU into the re-encoded HEVC.file:

dovi_tool inject-rpu -i GOT.S01E01.HDR.hevc --rpu-in RPU.bin -o injected_output.hevc

But somehow, I doesn't work for me. It keeps begin SMPTE 2086, HDR10. Dolby Vision won't be visible in the hevc output file. When I mux the hevc.file to .mkv, then it still is only HDR10, and not Dolby Vision.

What is the part where I screw up? I'm doing it somewhere, but I just can't put my finger on it. Or is it a cropping thing? Some help with this would be very appreciated!

Regards,

Tormented12

Try running the muxed mkv through MakeMKV

It worked. It now has the following in MediaInfo:

Dolby Vision, Version 1.0, dvhe.08.03, BL+RPU, Blu-ray compatible / SMPTE ST 2086, HDR10 compatible

Is this the right profile? Sometimes I see 08.06? If I encode 3840x2160 -> 1920x1080 without cropping, will I need to use the cropping feature from dovi_tool? Or wont it matter to use if the encode isn't cropped? And if so, do I manually need to set the cropping offsets?

I am trying to get the DV8 + HDR10 BL single layer with the yuesope's tool and I keep getting the same error:

Exception in thread Thread-5:SIS: 0.0% BL_EL_RPU WRITING: 0.0% (BL AUs: 105 EL AUs: 52)

and when I try to use the Dovi tool I get this message:

I was wondering if anyone knows how to fix this or if there is something else I can use?

No. Are you sure your TV doesn't support profile 8?
It works on the C8 with ts files.

So I've tried using mp4muxer and I've converted this mkv file:
Dolby Vision, Version 1.0, dvhe.08.06, BL+RPU, HDR10 compatible / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible
to this mp4 file:
Dolby Vision, Version 1.0, dvhe.05.06, BL+RPU / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible

The mp4 file plays fine on my LG C7 and even the DV logo is displayed. Is it possible it could work or do I just get some sort of fake DV?

I don't know. You could try remuxing the file here: viewtopic.php?p=113537#p113537
In the same way, if you see changes then it should probably work.

Yes! I can see the changes.
Thank you for your help!

What's up with the new Firetv stick? I don't know if it was the same with the older one but here's what I'm noticing:

1- no 24fps support on plex ... 23.976fps is fine
2- if display settings are set to '' AUTO 4k max '' then everything that is not 4k plays in 1080p on plex. (no upscale to 4k )
3- if display settings are set to 2160p 60hz, then 1080p videos are played in 4k but then the framerate match doesn't work anymore on plex
4- display settings ''AUTO 4K max'' , 4k movies on iTunes/appleTV plays in 1080p
5- display settings '' 2160p 60hz'' , DV movies play in HDR10 4K on itunes.
6- frame rate match doesn't work at all on iTunes.

in fact , it looks like only the amazon prime app works properly. I don't have a Netflix account.

1- I played a 1080p24 file and Plex matched it to 24Hz, confirmed with System X-Ray. HDMI set to 24Hz.
My display settings are set to Auto.

2- Played a 720p25 file and it is sent as 720p50 to the TV.

Are you sure you're matching the resolution as well in Plex?

3- I'm pretty sure not setting to Auto makes the OS hide the different refresh rate modes, it was the same on the 2018 with Kodi at least.

Netflix logged me out so I don't want to bother trying it, but I'm pretty sure it did 2160p.
