Dolby Vision now possible through MP4 Mux.

We need a real profile 8.4 file and delay the rpu. Iphone recordings are not dynamic I think, so it wouldnt work.

Should be simple to make. Apple uses a static reshaping for HLG to PQ in iPhone recordings.
I would assume they are limited to 1000 nits.

Would need people to test on the Apple TV 4K though, since it supports profile 8.4.

I have an Apple TV 4K 2021 and an iPhone 12 Pro Max, so I can help.

I don't have an ATV4k anymore nor an iPhone but it would be nice to have a true p8.4 test file(only thing missing in my test files).

I and a friend of mine have tested the file on these devices:
Sony X700 and X800m2 does not trigger DV but Sdr
Dune Real Vision 4K triggers DV with internal player
Firestick 4k max triggers Dv using kodi.
ATV 4k triggers sdr both with infuse and plex.
Tv's are Lg C8 and Lg Cx.

Sony X700 and X800m2 does not trigger DV but Sdr

remux it to TS and it will work. The MP4 version in my dovi test files GD folder should work as well.

Which files? Also didn't you have a ugoos have you tried on it?

You are right. remuxed in ts it works. And it works also in ATV 4K via plex. Thanks.

Any review on the Dune HD Real Vision 4k? Is it a good alternative to the sony x700 when it comes to playing dolby vision files?

I uploaded a good mp4 version from your HLG test file: https://1drv.ms/v/s!Ahh4FiB9hIuT-EK3sg5 ... j?e=RKiQG4
Interestingly, neither Apple TV 4K 2021 nor Dune Real Vision 4K handles RPU from the 8.4 file, only Shield.
I made a capture from my Shield: https://1drv.ms/v/s!Ahh4FiB9hIuT-EPZwIY ... Y?e=8CekDj

Hi i tried your mp4 HLG
HLG test file: https://1drv.ms/v/s!Ahh4FiB9hIuT-EK3sg5 ... j?e=RKiQG4
This is Dolby Vision detected on my tv when using mp4. Version 1.0, dvhe.08.07, BL+RPU, HLG compatible
Using ts4muxer, ts version remux. i got HLG only. Dolby vision logo not appear.

UPDATE: I forgot to mention: The HLG test file = The Rpu and the video mismatch.


i cant got DV working using tsmuxer. Do you have any DV reported working ts to test?
With tsmuxer also i cant get mux DV 5 profile. The mkv with wrong color and the mp4 DV with DV logo on and correct color.

https://www.mediafire.com/file/dj1hifc4 ... e.mp4/file

The mux for other samples with ts, also get jitter.
this

For now on, i still use mp4muxer for Atmos / DV titles.
The problem the mp4muxer dolby cannot insert delay audio if there is, unlike other muxer has -delay option
The srt substitle also cant get muxed into, unlike m4v subler for mac or old mp4box with yamb.

check the spreadsheet in my signature.


*** I think I found an issue with the x800m2:

1- DTS-HD 2.0 plays only as lossy DTS (core)
2- DTS-HD 7.1 seems to always be out of sync about 2 frames (83MS) but strangely DTS-HD 5.1 is fine.

Thanks! That's helpful. Any idea whether those also happen with the x700? Any chance it could be worked around by flagging 2.0 and 7.1 streams as 5.1 in the transport stream?

How likely am I to notice an issue playing back FEL Blu-rays with the Dune HD Real Vision 4k? Will I see the flickering issue with movies like Saving Private Ryan, or will I just be missing out on a bit of detail?

Just got the x700 today. Notice one issue: when I start playing a dolby vision file from an external hdd connected to the x700, the tv goes blank and shows no signal for a few seconds before the film actually start playing. Any fix for that? My TV is LG OLED C9.

That's normal, the TV switches refresh rate to maintain judder free playback.

By the way, I leave Dolby Vision setting On, and notice: SDR contents play correctly without being converted to Dolby Vision, HDR10 content will appear muted in term of colors, and Dolby Vision contents seem to play correctly as Dolby Vision (my tv is lg oled c9 and the dolby vision tag appears, indicating dolby vision content is playing). This surprised me as I read before that enabling Dolby Vision on the x700 will force Dolby Vision on all the contents?

Another thing: subtitles that come with some movies are too bright in hdr. Is it possible to use external subtitles? Will their brightness be lower if I do?

Wow after months (if not years) of questions about the x700, you finally got one lol...
It will convert sdr/hdr10 to DV when the video is: BD, TS, M2TS or BDMV folder. So MKV files play in the native dynamic range but then TrueHD no longer works.

never noticed an audio issue on the x700 with TS DV files.

Yeah lol mainly because I have to wait for the rest of the home theater to arrive. Covid has caused terrible shortages in my country.

It will convert sdr/hdr10 to DV when the video is: BD, TS, M2TS or BDMV folder. So MKV files play in the native dynamic range but then TrueHD no longer works.

I tested two hdr10 films: Black Widow (original bluray structure converted to bdmv folder using tsmuxer) & Raya and the Last Dragon (mkv remux converted to bdmv folder using tsmuxer). When I play them on the x700 with Dolby Vision left ON, both are not converted to Dolby Vision; instead, the colors on them appear muted, like when you play an hdr film on an sdr display without any conversion. Turning off Dolby Vision and those films will play in HDR correctly.

Some more observations:
-For hdr movies, subtitles appear too bright. This is not the case with dolby vision movies.
-When I play mp4 dolby vision file (the book of boba fett season 1 episode 1), it stutters at certain points.
-We can't fast forward or rewind to an exact point of a movie (like what we can do on pc)?
