They just don't have an option in the display settings to select it. instead they use the TV EDID to choose the DV mode.

Okay, not sure then. It might just be a bug with the older Sony TVs.

That's strange, I assume you tried my scripts?
if not then try the mp4muxer P8 modes or nightly tsmuxer.

I tested your script the movie I wanted to convert to MP4 DVI to work perfectly I had not seen your script in your description, Thank you for your work

I've added profile 8.4 generation based on iPhone 13 RPU samples.

Profile 8.4 L2 tests: https://mega.nz/file/0RMX1I5b#eULlLdOrg ... BRERfgWICw
It might need to be remuxed depending on your device.

Also remade the L2 test file in CM v4.x with the minimum required blocks, so it's still L2 only.
Profile 8.1: https://mega.nz/file/tc0nkBjY#LsBfxDMUh ... EUXe2vjCgg

For profile 8.4 HLG I tested it on my side and it works. I can't see a difference between 8.1 and 8.4 by eye.
FireTV Stick 4K Max (2021, latest update): plays in Dolby Vision, L2 metadata works.
FireTV Stick 4K (2018, old update): plays in HLG, wrong colours.

I've blocked updates on my 2018 stick, so I can't test if it was added.

If anyone wants to test on other devices, feel welcome.

Many thanks, I'm tried with Apple TV 4K 2021 + Infuse, but the ATV does not handle the RPU. I will report to the Firecore forum.

Using Reset_9999's scripts and had some questions:

How accurate is the conversion of HDR10plus to DV? Anything I can do to improve the conversion? I don't have an HDR10+ display to compare.

Also, sometimes I end up with both an .hevc and a .bin file when using the script, etc. Do I need to do anything with the .bin or just mux the .hevc into a mkv? I'm not losing anything by discarding the .bin, correct? S

@quietvoid:
I also created mp4 and ts versions of your test files: https://1drv.ms/u/s!Ahh4FiB9hIuT-ETf93f ... D?e=nOgBuQ
Is it possible that the Apple TV could only read the RPU from the mov container? How can I make a mov file?

Not sure. ffmpeg isn't keeping the Dolby Vision config when converting to mov. Only mp4.

nop, you cannot improve the conversion. it's the best you can get with the input source you have.

you can delete the .bin file.
I keep a copy because I want to share the rpu with my friends.

For movies with neither a Dolby Vision track nor HDR10+ metadata to convert, how much of a difference am I likely to notice on an LG C1 between auto-generating shot-by-shot metadata versus just playing it back with static metadata? Is it more likely to make a difference in a brighter room (so Dolby Vision IQ can do its thing) than a fully dark room?

Finally, is there any way to generate shot-by-shot metadata on Linux, or do I have to use the madMeasureHDR.exe program under Windows?

Thanks.

I just made a profile 5 doblyvision encode (now-possible) encoded on a pc
This test was made from a hdr10 base layer.
And it works on apple

tv
I’ll wait for reset9999 to compare

HDR10 with madvr-generated DV is certainly better than just static HDR10. You will notice a difference, especially with bright content.
I dont know about Linux.

@RESET_9999 Thanks for the quick reply!

Another issue (and I've spent time searching the forum via Google so sorry if this has been covered):

When I do WEB-DL only hybrids i.e. both DV and HDR are from WEB-DLs, with most films I get audio that is wildly out of sync. TV shows have no issues, strangely. Source files are MKVs, I use the hybrid maker script, then mux the resulting hevc file with the HDR file's audio and subs using mkvtoolnix gui.

I saw some mention of trying better release groups, but has anyone had any success in resolving this? I am using two files from the same release group and confirm exact same length via jumping to specific frames, etc.

I tried some various things, using TSMuxer to turn the end MKV into a TS seemed to get the audio only a second or so off...while the MKV was WILDLY off. So odd.

Here is a p5 sample for u guys to test
This was encoded using doblyvision encoding engine & h265, RPU is a true P5 even l4 included
Source file spares & munsil m2ts untouched Mel.

Thanks, I will try tonight. Maybe you could make a mov file from the recently linked P8.4 L2 test file?

Thank you. Tested on ATV 4k works perfectly via Infuse but no audio.
Also for a couple of secs woksr on plex app before a message appears on the screen, plex complaining the network speed is too low (it is wired gigabit).
