To avoid subtitle time difference, I use tsmuxer to extract the main file of the movie with Dolby Vision. But when I use MKVToolnix to convert from .m2ts to .mkv, the MediaInfo of .mkv file notice there is only 1 video, not 2 videos in the .m2ts file. Why is that?

It looks like you forgot to select the 2nd video in mkvtoolnix.

May I ask what this subtitle time difference is? Is this why you use mkvtoolnix as intermediate?

It's overlap in .sup file if I use MKVToolnik or DVDFab to create .mkv remux from BDMV.
If there is a overlap of the original subtitles, the Vietnamese subtitles that I need to sync will also be wrong.

Thanks for sharing. I doubt if a remux by those tools could cause such issues. Maybe the overlap would actually exist in the source PGS stream itself. If so, the disc would suffer from a major authoring issue.

However, it's not uncommon for a subtitle OCR process to misinterpret accumulative SUP images. Looking at your screenshot, I can imagine lines 37 and 38 being an example of faulty merging of several (on disc, well-authored) lines. Did you compare the actual PGS images at these timestamps?

Hi,

If I may : what is the best choice, between Zidoo Z9X and Dune HD Real Vision 4K, for playing DV using Kodi and Fen/Seren/Venom (or a Kodi-like app) ?
By playing DV, I mean MKV/MP4, and more profiles supported than by my Shield Pro (Remux-friendly, and without messed up colors).

Thanks for any help.

I had the same issue and went with the Dune based on user feedback. Seems like they are better at firmware/software updates then Zidoo. With that said, I have not seen or used the Zidoo. I have confirmed that the Dune HD Real Vision 4k Solo plays both DV 7 profiles. You are going to want to use the built in player no matter which one you go with. Due to either licensing or content providers not allowing it, they are limited to at best, 4K no HDR and Prime video is actually 480p. There is some weird licensing with content providers or they get to choose who gets 4kHDR with streaming services. The Dune is hands down the best media player I have ever used. The fact that it does resolution and framerate changes with no HDMI drop outs is a huge plus. The built in player is all you need really. It does come with a YouTube variant that can actually play HDR. In fact yesterday I was watching something and it came us as HLG. Bohemian Rhapsody, one of the few HDR10+ movies available looked and sounded amazing. It's not for Netflix, Hula, Dis+, ect... The Android in both is crippled by resolution limitations. I only use my Shield now for streaming services. It plays DV profile 4, 6, 7 *MEL and FEL, and 8. Most remux's use 8. HDR10+ (shield doesn't support), HDR10, and HLG. I can't confirm profile 4 due to my setup and it being STD (display does tone mapping, not LLDV). The one thing you will notice right away is no judder, especially compared with the Shield. I had issues with Judder on some content on the Shield. Being able to send out 12b LLDV for SDR content helps with banding and it properly remaps the color tones for pretty much any scenario. While still in Beta, the new GUI is a huge improvement http://dune-hd.com/firmware/newgui/

Yes, I've compared PGS images at these timestamps of genuine Blu-ray disc and .mkv rip from MKVToolnix or DVDFab.
If rip from tsmuxer and convert to .mkv by MKVToolnix, this error will not exist.

I’m looking at getting the Sony X800m2. Before I do I’d like to see if Dolby Vision Fel is worth it. Does anyone have a list of films where the Fel is a reasonable size?

@RESET_9999
Which madVR version is in your tool?

[userr]

Can anyone tell me pls, is there a point in playing profile 7 dolby vision with enhancement layer if i have a Sony Player-LED TV? Can it display the additional details that comes with enhancement layer?

[RESET_9999]

@RESET_9999

the latest beta without time limitation: 113B or 114 if I recall correctly.

Can it display the additional details that comes with enhancement layer?

yes it can and why wouldnt it? ( as long as the player is sending the information to the TV)
The player-led bug is not related to the EL and it affects Dolby Vision without EL( profile 8 ) as well.

Thank you, i wasnt sure if it would thats why i asked.
What is the player-led bug? Havent been keeping up with DV in a while

From what i can gather from reading just the last pages, it seems Zidoo Z9X / Dune HD Real Vision 4K is the way to go for profile 7 mkv playback?
Or Sony x800m2 for mp4 i guess?

For those interested in DGDemux: The writer of the tool created a utility to merge the gap-processed demuxed, separate TrueHD and embedded AC3 tracks back together into TrueHD+AC3.

http://rationalqm.us/board/viewtopic.ph ... 406#p15406

I tested this new tool and it worked very well and this is exactly the solution I was looking for the other day: a way to merge thd with ac3 without encoding the core in eac3to.
Took about 3min for a 2h movie when eac3to usually takes more than 10minutes.(more if clipping detected).
Obviously, you have to demux the mkv first(and ac3 track must be present) but it still faster thanks to my NVME drive (+ most of the time i have to demux the hevc too anyway)
The fact that it can fix the gap from makemkv files is great as well.

I hope it plays well on the x800m2...
