Dolby Vision now possible through MP4 Mux.

[Oleg_NYC]

I wish someone would answer my question. If I have a profile 8 DV video and use "mp4muxer --dv-profile 5" to mux it into an mp4 file, then will the video still be profile 8, but have the fake id of profile 5?

Yes, it’s p8 with fake id. The profile is more like a header to indicate type of DV, but it’s the data within RPU that truly matter. I don’t understand why would someone want to do this unless they are Apple user.

When I use DLNA to stream mp4s containing videos with profile id 5, then Dolby Vision will be triggered on my LG TV. But this solution only partially works because the internal LG player had problems seeking in at least one of those files. All those mp4s have the fake profile id 5, but before
they were remuxed, they were profile 8 mkvs. The internal LG player won't ever play mp4s with videos whose id is profile 8. I don't know if buying the Amazon Fire Stick will allow me to stream profile 8 mkvs to my TV and successfully trigger Dolby Vision. What about attempting to mux a video and an audio into the m2ts container, not the mp4 container? I still can't figure out what command I should type to make tsMuxeR do it for me. "tsMuxeR BL_RPU.hevc audio.ac3" seems like a wrong command... So, please tell me what I should do.

Yes it can be done. You will get unofficial MEL.

Is there a large difference between MEL and FEL?

I'm beginning to think it's just not worth the hassle of finding a P7 FEL player. If I can convert P7 MEL to P8 then it opens a much larger set of players, etc.

To be honest with you, I completely abandoned my Zidoo Z1000 Pro player (which plays it all hassle free by the way) since member @RESET_9999 basically taught me how to utilize the “dual track-dual layer” files with my Sony X700 UHD player, using his fantastic DoVi Scripts (the link can be found in his signature).. I can tell you straight away - there is no comparison. The image produced by the Sony player from a Profile 7 FEL DV file is by far superior to the one produced by the Zidoo player (which cannot utilize the full fat DoVi) - the richness of colors, the absence of any color banding, the depth of the image, etc. - all far superior, basically no difference compared to a Dolby Vision UHD disc. BTW, I am ripping the movies to a full Blu Ray folder in order to be able to use FF/RW and chapters within a movie.

I notice color banding in several movies. For example, the WB logo during the opening of Interstellar, or the logo (forgot the text) during the opening of Spiral: Book of Saw. Not sure if it's the content or the x700. X700 uses TV led dolby vision automatically when the tv supports that right?

I wouldn't describe picture-quality difference using such superlatives.
In my experience, (properly processed) FEL does not always yield the same impact. Sometimes the difference to BL + RPU is obvious, sometimes it's very hard to tell any.
Having a Z9X, eventhough bothered with all Zidoo quirks and suffering from a seemingly neverending firmware saga, I never noticed it showing any color banding. Not for "regular" video, nor for DV material. And regardless of whether FEL is ignored or not present. As a sidenote, I can imagine switching DV mode from "tv-led" to "player-led" may have influence.

But, having UHDBD players also, I would agree that their full blown FEL playback overall beats a mediaplayer.

I used the 4K UHD rip (BDMV folder) of the movie “Hobbit - An unexpected journey” to test the differences between the Zidoo and the Sony X700. I believe it is profile 7 MEL. Compared to the Sony, the Zidoo appeared to produce a somewhat softer image with less depth and at times too “digital”. The colors were not as vibrant (for example the grass around the hobbits’ houses, as well as fire scenes). The Sony also gives a brighter DoVi image for some reason.

Which version of TS muxer knightly is better for LG OLED E8 2018 to make dolby vision ts conteiner from mkv dolby vision ? Cause newest versions TS MUXER don t work on oled lg 2018

I don't mean to change the subject, but I had another quick (haha) question...

Can Dolby Vision be decoded on a PC to display on an HDR monitor?

For example, the Alienware AW3423DW QD-OLED PC monitor doesn't support Dolby Vision but it does support HDR10.

Can a powerful enough PC decode the Dolby Vision and convert it in real-time to HDR10?

I'm guessing the answer is no but it seems possible? (unless the Dolby Vision encoding can't be decoded or hasn't been 'broken' yet?)

Just tested a HDR10 movie (Dunkirk) - the results are the same. It is not Dolby Vision per se - there are processing differences between the X700 and the Zidoo. The X700 is simply better. Waiting for delivery of a X800m2, I hope there will be some (however slight) improvement over the X700. Maybe not.

Please correct me if I'm wrong, but this sounds like you're comparing "player-led" modes. Which on itself is fine of course. I've always experienced a nicer image when tonemapping is done by (my) tv. Therefore, I always have "tv-led" mode set.

Can Dolby Vision be decoded on a PC to display on an HDR monitor?

Not so for "power", I doubt if there is or ever will be any soft- or hardware that can convert all DV into static HDR video. Dolby Vision profiles are a mix of single- and duallayer videostreams, different HDR families, and profile 5 is even encoded in a DV proprietary colorspace. RPU is dynamic, which has to be converted into static HDR10 metadata. If there'd be software or hardware that can take care of this all, I would be surprised tbh.

Some DV profiles already carry HDR10 video, which can directly be played back on a HDR10-supporting monitor. Where RPU and possibly present FEL will be ignored of course.

TV-led on both devices.

Is there a way to check if the x700 is playing tv led dolby vision instead of play led?

[powdeau]

So how big the issue is with the L1 bug on C1+x700 in real content (BD movies)? Is it night and day difference like in the pattern videos? Is the DV on BD still better than HDR10?

I have the Philips HDMI Sync Box between the tv and both players (Sony and Zidoo). The Sync Box synchronizes the lights of different Philips hue products to the image on the screen.

The Sync Box works with Dolby Vision only if it’s player-led (LLDV). It doesn’t work with TV-led Dolby Vision, unless I switch on the “Dolby Vision Enhanced compatibility” option inside the Sync Box settings. This option basically forces the player to switch to LLDV and then the lights work. So if the Hue lights sync without the DV enhanced compatibility option checked - it’s player-led DV. If they don’t work - it’s TV-led DV.

Does the x700 switch to tv led dolby vision automatically when the tv supports tv led dolby vision? There's no option to switch between tv led and player led on the x700.

I think this is precisely the way it works. I believe it will always send TV-led DV (8 bit) if the TV supports it, otherwise it will send LLDV (12 bit). There is no option to switch between player-led and TV-led on the Sony, I think Oppo 203 has this option (as well as the Zidoo players).

Do you guys see any difference perceptually with TV led? Or just want it cause it's technically better? I know even if you see something it could be subjective in perception, etc - just curious really. I feel like when I watch a FEL for example the image has more depth to it it seems.

[RESET_9999]

it depends on which player you use. On the x700/x800m2/Shield the L1 and L2 trims are not working at all in LLDV.
