Dolby Vision now possible through MP4 Mux.

*** 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)?

I converted the mkv remux version of Raya and the Last Dragon (2021), which only supports hdr10, to bdmv folder and when I play it on the x700 and Dolby Vision left ON, it's not converted to Dolby Vision; instead, the colors are muted, like when you play an hdr film on a sdr display without any conversion. Turning off Dolby Vision and the film will play in HDR correctly.

strange ...
are you sure the mkv you remuxed wasn't profile 8 hybrid? I think P8 muxed in BDMV plays in SDR on the x700.

I edited my comment above after I did some more tests.

How do I check the profile of the file I have?

Thaks. I will check the dv profile of those films later and report back.

Regarding your spreadsheet, does the bdmv trick works for all dv profiles or just dual track dual layer?

yes BDMV is for dual-track dual-layer files

BDMV is ideal for FEL DV movies. For all the MEL bluray or Hybrid DV releases, profile 8 TS is the best you can get on the x700 (bug-free).

Most, if not all, of the profile 7 Dolby Vision films that I see show Video #1 and Video #2. Does this mean they are dual track? Is there any particular film that is profile 7 single track?

[stn17]

It's not really correct place to ask, but I figure the best, since many of you did analyze various aspect of streaming services content.

Is lossy dolby atmos from streaming mixed the same way as lossless dolby atmos from disk?

In other words, which one is better:

Dolby vision FEL + Dolby Atmos DD+ from streaming
Dolby vision FEL + 5.1 DD+ 1536kb/s from Dolby Atmos 7.1 disk track

DV profile 7 is intended for UHDBD. It holds a base-layer and enhancement layer, which are muxed as separate videotracks in a m2ts container. So indeed that is called "dual track dual layer". I've never seen a Dolby Vision UHDBD that has one videotrack. MP4 can also be muxed as dual track dual layer.

Software like MakeMKV interleaves the two layers into one videotrack. The result still is a DV profile 7 mkv, but obviously now it's called "single track dual layer".

Does anyone know a way to reduce the brightness of subtitles in hdr? They are blinding in dark scenes.
