Dolby Vision now possible through MP4 Mux.

It requires re-encoding but it can be done in resolve. I actually convert all my SDR bluray to HDR/DV.

For titles that don't have UHD/UHD web releases? Or for all just to have a 1080p HDR/DV library?

Anything I want to watch that doesn't get an official HDR release.
Only DV is allowed in my Home theater, I haven't watched SDR/HDR10 in years.

Can Resolve produce DV from SDR? Will the result be better than RTD1619DR using VS10?

no idea if it can produce metadata for an SDR base layer. I guess it can but never tried.
I convert the sdr bl to pq.

Hi, I've found what the issue is with Disney+ (at least with ffmepg), it's the presence of chapters in mkv file (which get copied to mp4).
-map_chapters -1 does the trick with ffmpeg.

Thanks, I'll try.
If you collect in mp4box, then the absence of chapters does not affect the performance, it has been checked repeatedly
P.S. So, I conducted tests, used material from Disney, if you assemble using ffmpeg, there really are no problems with sound, but it remains unpleasant as after assembly in mp4box, namely, there is no possibility of switching subtitle tracks, of course we are talking only about playback over the network (NAS or DLNA). Perhaps you know how this is solved?

I've figured out I can only playback Dovi files on my TV from USB/Network, however I only ever get HDR from the 4K remuxes.
The DOvi test files show Dovi just fine, but obviously I don't care for watching those
I'm trying to play them back on a Panasonic LZ series OLED. What needs to be modified in the MKV to allow the TV pick up the stream?

Hi @RESET_9999,

As always, thank you for maintaining the amazing script and tirelessly testing DV displays and releases. A few feedbacks:

1. On line 10467 in the DoViBaker workflow, the path to DGDecodeNV.dll is hardcoded instead of referencing DGIndexNV_path.

2. I tried out the new DoViBaker FEL screenshot workflow. First of all, great stuff! I was able to compare the BL vs FEL on Criterion's Three Colors: Red and confirm that there's basically zero recovered detail from their filtered BL. One pain point though: It appears that we still need to manually take screenshots through AvsPmod. Do you know whether AvsPmod is scriptable? Would it be possible to automatically take X sets of BL vs FEL screenshot comparisons from a given clip? Obviously you can't select ideal frames for screenshots this way, but it's still useful for a quick comparison to see if the EL contains visible information.

3. The 1.8.3 release notes currently suggest "copy[ing] the dovi.dll into 'C:\Windows\System32'". FYI it doesn't need to be System32--any dir in the Path environment variable would do. IMO it is a security risk to ask users to copy binaries into System32.

4. On line 10385, have you considered making the sample maker's timestamp range configurable at the top of the file?

5. On your GRADE/MASTER CHECK (P8 DV HYBRID) sheet, some titles are released in different regions with different gradings/ecnodes by different studios, so clarifying the version may be helpful. For example, Paramount's Arrival (2016) in the US/UK looks different from Sony's in the EU and all the DV WEB-DLs I can find seem to be Sony's grading. (From what I've read, Paramount's grading is more faithful to the original.) Another one would be Escape from New York (1981): Both Shout Factory and StudioCanal's releases have DV FEL. Wondering which one is your plots taken from?

Finally, a question I've been curious about but don't know where else to ask:

Does anyone know how DV tone mapping interacts with ABL? Say we play a prolonged 1000 nits sequence on an OLED with 800 nits peak brightness. Initially the panel can tone map that according to its (statically stored) peak brightness capabilities and an extrapolated curve from metadata in the L2 trims. But as time goes on and ABL kicks in, does the DV engine have access to the now lower peak brightness number to tone map from there?

Thanks again!

good point, most of the time I don't actually know the version I'm downloading lol.
I'll try to add the region info next time.

right will fix next release. thanks

yes I could do that

yea I just followed dovi_baker github instruction. Good to know thanks

It appears that we still need to manually take screenshots through AvsPmod. Do you know whether AvsPmod is scriptable?

I don't think avspmod can extract screenshot via command lines.
I guess I could script something with ffmpeg though.

Next version will make a FEL and MEL script for easy comparison. I also added some overlay text.

Thank you for all these!

if you want to save some time, I already generated DV in resolve for most of the movies, here are over 600 RPU files ready to be injected

Code: Select all

And wow I was just catching up on the thread and found I missed this. The link is dead now. @RESET_9999 any chance you could PM me a copy as well? I only have 2 posts here so far so can't PM you yet. (Can I receive PMs?)

probably because the zidoo wrongly send a bt2020 flag with the TV-LED signal.
When I tested this device a very long time ago, it was slightly affecting the colors: Green, yellow and blue were paler and red darker.

IMO that bt2020 flag is just a red herring. My Panasonic UB820 also sets it for DV.

[TheEqualizer]

Please tell me if there is a way to make switching subtitles on built-in LG TV player during network playing a .mp4 dv 8 profile, or is this the normal situation (limitation) for LG software? Perhaps any additional point when building in ffmpeg needed?

[RESET_9999]

Thank you for all these!

DoVi_Scripts_1.8.4.2.beta now has a workflow (6-8-2) that can ''quickly'' export 5x FEL/MEL PQ screenshots. (will only work if your input is at least 36min)
It's random so just because those 5 screenshots don't show a difference doesn't mean there isn't one on another shot. Plotting DV and HDR10 is a better indication of brightness expanded via fel.

IMO that bt2020 flag is just a red herring. My Panasonic UB820 also sets it for DV.

It's been a while since I tested this but the bt2020 flag with RGB tv-led definitely did change the colors slightly but nothing major really. And I when I tested that, it was before the @yusesoap profile8 era so I only tested profile 5 patterns.
If you have an hdfury device, you can remove it. I tested the Zidoo and Shield (they sent bt2020 flag too before) and both had different colors with the bt2020 flag.

Those other differences in the signal you found are very interesting though.

any chance you could PM me a copy as well?

Markswift says that the TV does not handle this bt2020 flag during signal processing, maybe some TVs handle it differently?

The zidoo guys (mirrors and mark) often say things without actually testing them. I don't put too much attention to what they think or say.

done.

Hey @RESET_9999,

Using your script, is it possible to output a profile 8 DV MKV using 2 imputs??

Input #1 is a MKV with HDR already created from the UHD disc rip.
Inut #2 is the UHD disc ripped to folder.

I see you can convert the UHD disc to DV profile 8 MKV but I would prefer to add DV to my existing MKV file as I have already re-encoded it to make it a bit smaller and burnt in my subtitles.

[RESET_9999]

Input #1 is a MKV with HDR already created from the UHD disc rip.
Inut #2 is the UHD disc ripped to folder.

No, but you can use (2-2) to extract the rpu from the original dual track m2ts and then use (1-1) to inject it into your encode (will be converted to P8).
If your encode is cropped, the rpu will be cropped.

Cool, thanks. I'll give that a go...
