Dolby Vision now possible through MP4 Mux.

It most likely was a mistake.

Thanks - if @RESET_9999 wants to update his test pattern repo, here's the corresponding one without cmv4 using dovi_tool/MP4Box: RPU.p8.1.L1.L2_cmv29-ONLY.mp4

I also had posted about it but I guess it was missed: viewtopic.php?p=124890#p124890

good catch. I'll update the files.

In case you aren't aware yet, @RESET_9999, DGDemux since build 65 (Feb 15) has renamed its outputs from *.265 to *.hevc. Current version of DoVi_Scripts (1.7.7) would fail with "The system cannot find the file specified" when looking for the demuxed BL and EL, because of lines like:

Code: Select all

FOR /R "%TEMP%" %%B IN (*1011*.265) do set "BL=%%~nB
FOR /R "%TEMP%" %%E IN (*1015*.265) do set "EL=%%~nE

I only tried mode 4-1-2, but this should affect other modes as well.

I didn't update my dgdemux in a while. I'll make the changes, thanks.

sorry for this OT Q, is there a reliable method to check a DoVi BL video colour range (full vs limited) ?

I have found few methods online that analyze the BL using ffprobe lavfi.signalstats.[YMIN,YMAX] where results may conflict with the metadata in either video container headers (ffprobe pc/tv) and/or RPU info. (or the info is unclear based on my limited understanding)

I don't understand what you're trying to do.
The RPU levels are always full range.

The only time the BL is full range is if it's profile 5.

My question was how can the range be checked for a Dovi P5 BL or another profile aside from inspecting metadata? Sorry if it was unclear.

Aside from RPU metadata full range flag, is there a tool or some means that can confirm that the video stream/contents are indeed full range for a P5? I shared above the ffprobe technique. Thanks.

Not reliably by looking at MediaInfo or FFprobe because some aren't flagged as full range.
So analysing frames should work I guess.

Hello @ RESET_9999!

I recently bought a sony x800m2 and I wanted to test if the player is playing FEL DV files correctly over network.

I tried looking at the files in your signature but the Power Rangers file is in MP4, which to my understanding, does not work over network.

Do you have any file that I can use to test this?

right, MP4 files don't work via the network. Did you try to remux it to TS?

Hi @RESET_9999,

Thank you for your Dolby Vision scripts, these things are pretty sick mate.

I am trying to use them as there are some WEB-DLs of a Disney+ show my wife and I like to watch, however the releases for the show are in 4K HDR and 4K Dolby Vision exclusively, there isn't a hybrid release with both sets of metadata. After watching your tutorial vids (as they are slightly old and differ a bit from your current scripts), I assume the workflow I want to use is:
---------------
1) MODE.I= DoVi Convert/Edit/Sync/Inject two inputs (P8 Hybrid maker)
1) Workflow.1= Base Layer file + ST P5/P8/P7 DoVi file (can also mux and convert audio)

(Drag and drop the HDR release, then the DV release)
---------------
After this is where some options differ from your tutorial clip. I assume I should be choosing 'no' for L6 edit, then the next option I am confused on what to choose. Should I be using duplicate or remove for re-sync the RPU? On my own try I didn't choose either and it spit out an MKV with what looks like both HDR and DV metadata when inspecting with MediaInfo, however I haven't had a chance yet to try it on my TV.

Would you be able to just confirm what I should be choosing for the re-sync RPU prompt if I want to just make a hybrid WEB-DL from the same P2P group that released separate DV and HDR releases?

[tjreis2]

I did but the file didn't open. Weirdly enough, when I open the MP4 it does work and displays the credits in bright white instead of grey, but maybe it's something because of the Dolby Vision on toggle...

[aboulfad]

Sorry for this basic Q, what equipment or tools would be required to take DoVi/HDR screenshots: media/blu-ray player to TV ? not using a camera : ) & TV doesn't allow screenshots when in DoVi.

For PC based tools, I realize that one can use a ffmpeg or mpv,... I couldn't try mpv as it seems gpu-next is not supported or possible on macOS to properly decode DoVi (&P5). Does mpv/Win properly/adequately decode P5? Thank you.

yes (1-1) is the hybrid maker workflow and no need to resync nor edit L6/L5 if both versions comes from the same provider, they are most likely the same length (same frame order).

The tutorials are indeed old, I will re-do them when I find some free time.
