Dolby Vision now possible through MP4 Mux.

I didn't think your users would care to just play in HDR, if they don't care about bitrate. But to each his own. For Dolby website, try another browser or incognito window, I think I had similar issue and used Edge.

[azreil24]

It's there, I checked.

then idk, show me the log with ''echo'' set to ''on'' maybe.
you can also try it manually:

D:\DoVi_Scripts\tools\madvr\madMeasureHDR.exe "D:\Interstellar.2014.iMAX.HDRg 2.9 itunes (4000nits).mkv"
Measuring video file "D:\Interstellar.2014.iMAX.HDRg 2.9 itunes (4000nits).mkv" using D3D11 (native)...

I get the same message even for manual call. Will give it another go tomorrow. Thanks for the help.

I played around a bit and it seems FFMPEG does not support native converting video with DV. I managed to get it working with this tool however: https://github.com/quietvoid/dovi_tool/tree/main

I had to first extract .hevc from original file and extract RPU. Then convert original .hevc to lower bitrate and inject the RPU into it. Then just replace the video stream in original file. This way I get HDR and DV correctly detected on my LG, no more issues with the brightness in DoVi mode.
There is a few step, but doable with some powershell script.

Might also be some issue with hevc_nvenc, as I use GPU encoding and not the cpu x265 encoder. I think with x265 you can pass RPU while encoding and not as separate step with --dolby-vision-rpu

I moved the scripts to another drive, as I had them in C: root, I know it's not recommended but it worked fine with all the other flows, moved them to the same drive I had them prior to moving to C. On the new drive, I still had the IMeasureHDR error, but after that it started giving me Python not found error, although it was installed. It seems that it only wants the Python version installed through Microsoft Store, for some reason, that is what the error message was suggesting to install from, while I initially had it installed from their website, as indicated in the Dovi Scripts installation documentation.

I then re-downloaded your tools archive and re-copied the madVR folder and it's now working. Not sure what happened there and why the error, but its working now.

I tried injecting the RPU data into my Akira copy and at the end failed saying it could not find the metadata XML in the temp folder, although this process worked fine before. I get the same error when using the 3-1 flow, as I wanted to play with it, but this XML file is never generated in the process.

"metafier: ERROR Unable to open Metadata file 'C:\DoVi.Scripts\temp.folder77\00000_DV.xml'"

you have to show me the full log with ''echo on'' if you want me to help you.

But it sounds like you didn't install avisynth plus.

https://github.com/AviSynth/AviSynthPlu ... 230715.exe

[azreil24]

Avisynth is also installed.

Let me know how can I share the log, as it seems the forum doesn't allow me to add any files.

Seems like it fails here:

You need the latest Cm_analyze.exe which has the L1 tunning.

[azreil24]

Yes sir, that was it. I copied the one from the Dolby install folder and it did the trick. Many thanks!

I've been recently testing DV on the Win11 Movies & TV app. I got both "Dolby Vision" and "Dolby Vision Extensions" plugins installed since I don't know what's the difference between them.

dolby.vision.plugin.png (37.16 KiB) Viewed 9441 times

I connected it to S95Z(S95C) and tried the CMv4.0 test pattern from quietvoid, most trims worked so I'm guessing it's LLDV (Samsung doesn't support DV). However, I noticed black level is raised and I got a dark grey when it should be completely black. Windows HDR Calibration app couldn't fix this. Any thoughts would be much appreciated thanks!

HDR10 content also has a very slight raised black in Movies & TV app but it's barely noticeable by naked eye, I have to take a 30 second exposure photo to really make sure and it can be fixed by the Windows HDR Calibration app. DV content black level is unacceptable compared to HDR10. Screenshot and SDR content look right, completely black.

Win11 is on 23H2, AMD driver 23.11.1, all softwares invovled are up to date.
GPU output is set to 10bit Full Range RGB HDR, TV input set to Full Range.

dont waste your time with the the Win11 Movies & TV app, the Energy player supports MKV/TS and profile 7 and lossless audio

Reset in unreleased version 20.1 which i renamed in MP4 .bat which numbers need for making from remux mkv 7 profile dolby vision to mp4 7 profile

[RESET_9999]

if you just want to mux the ST-DL MKV(or any dv file) to MP4: workflow 5
if you want to demux ST-DL MKV and mux to a DT-DL mp4: Workflow 4-3

new test file like the eagle beak sample but this time, the L2 trims are a positive lift. I haven't checked on my TV yet but it should show how trim offset not working in TV-LED is a problem
