Ok, so i found a 2nd hand X700 for 90$ and couldn't resist finally getting proper(?) FEL playback of backups :D

Of course all my backups are .mkv, as i thought that would be the golden solution... Guess not :lol: So thanks bits and pieces from this forum, i think i've narrowed down the procedure to convert DV .mkv to the format the X700 accepts off USB, and decided i would share it here for reference:

1. Demux the .mkv with gMKVextractGUI.
2. Use EAC3to GUI demux feature on the .thd file output from step 1 to create a .thd+AC3 file tsmuxer will accept (not needed for DTS or lossy audio?)
3. Run demux.bat from yusesope's BETA (not gamma) 0.0.4 tool and drop the .hevc file produced in step 1 here.
4. Put the BL.HEVC & EL_RPU.HEVC produced in step 3 & the .thd+ac3 file produced in step 2 (in that order) in tsmuxer (i use the nightly from 30/4), and tell it to output to a blu-ray folder.
5. Rename the folder to AVCHD and put it in the root of your USB storage for the X700.

Regarding subtitles, i add the .mkv to tsmuxer and select the subs i want. Maybe they can be used from gMKVextractGUI as well, but i had some none working ones on my first attempt, so playing it safe as i know they work directely from the MKV.

Any comments if i made a mistake somewhere, or made it overly complicated would be appreciated :)

Hi. I have OLED C8 which, from my understanding reads profile 7 FEL and MEL Dolby visions files encoded in MP4s.
Is it possible to take the newer DV dual layer mkvs and re-encode them in mp4 whilst keeping all the info (except Atmos?).
I feel like this has been asked before but all I could find was a tool to convert FEL to MEL which isn't what I am trying to do.
Any help appreciated.

Will your X700 also play the DV .mkv file with lossless HD audio tracks (DTS-HD or DTS:X or Atmos) via network share? Or this procedure you mentioned only works of connected USB drive?

Pr. my understanding it will not, but i am not totally updated on the subject, as this solution is good enough for me, given i don't have THAT many DV movies.

Thanks for your response. I have just recently ventured into ripping my 4K UHD movies and have a DV enabled TV but older (but working without any issues X800) and still exploring my options for DV playback device. Currently nVidia Shield Pro is my top choice but since it is already 2 year old since release I will wait to see what features will be added to its next iteration and potentially get the 2019 version for less financial outlay.

Yeah, i have had a shield pro 2019 since launch as well, and it does pretty much everything very well. But once people here told me about the red push issue, i started noticing it haha. Fingers crossed it will be fixed eventually (and less likely: add FEL support) Probably wouldn't have bought the x700 at full price though. Also it is possible that there will be a shield 2021 refresh, possibly even with a fresh chipset. We will see.

Hey guys, been having some trouble getting certain DV files to playback on my Sony XG9505 and I think I have identified the issue as being that my TV can't play profile 7 FEL but can play MEL?

I done some testing and I got the following results, which confused me at first as it seemed like since all the files were the same either all would play in DV or none should, but then stumbled onto a list on I think blu-ray.com identifying which releases were FEL and MEL and it seemed to line up with what I could and couldn't play.

Am I right in saying that if I extract the HEVC stream from my rips I can use dovi_tool by quietvoid (dovi_tool -m 1 convert filename.hevc) to essentially convert the FEL DV into MEL (which in reality is just removing the enhancement layer?) and then mux the HEVC file back into the MKV I should have a working MEL release with HDR10 fallback? Since the MEL includes dynamic metadata, it should also still be an improvement over just HDR10, but not quite as good as full FEL playback?

Guys i tried to read into that but couldnt find answer.
Is it possible to take Bluray profile 7 DTDL and convert it into STSL profile 5 cause it seems that my LG CX is only capable of playing this instance of DV files. I tested and its working with rips from ex. Disney+ Falcon and Winter Soldier DV file from rarbg which is indeed STSL profile 5.
Thank you so much :)

Convert to Profile 8.
You will not lose that much with dropped FEL.

Possible, but it will be p5 with YCbCr colorspace and TV dovi decoder may expect ITP in p5. In this case colors will be very wrong
Try Profile 8 at first.

Profile 8.1 not working properly after conversion. It is not read at all. The funny thing is that dual track dual layer MEL movies using original mp4 method are working entirely correctly. (Tested on Casino Royale UHDBD rip).
But when the movie is FEL and I use the same mp4 method on that. For instance Game of Thrones episode, then it is read but its darkened very much which is definitely not correct. So i am looking for a way to convert FEL to MEL without changing to profile 8.1. Just leave it at profile 7 or convert to profile 5 which are both read as long as its MEL.
Best Regards :)

What are the benefits of profile 8.1 instead of profile 7 MEL?

It's the same. P7 MEL is used for Blu-Ray disks and P8 is pretty much dead. Dolby Labs only recommend using P5 for streaming services. P8 is used only by MakeMKV members and Torrent users I guess. The community here collectively attempted to use the P5, but we lack the Dolby's proprietary tools for it. But we were able to come up with methods and create tools to reproduce a correct P8 videos, which is the same as P7 MEL. Pretty much credit goes to user yusescope. Has not shown any activity lately

Some dovi decoders don't work with P7 but work with P8.1
P8.1 is almost equal to P7 only difference is VUI Chroma Sample Location value. For P7 it's always 2, for P8.1 can be 2 or 0.
That's why P8.1 is the best option to convert UHD BR P7
Sadly, not all devices capable to play P8.1. Like 2016-2018 Bravias.

Fire TV 4k HDR devices and CCwGTV do support both profiles. The ladder even supports the FEL P7 too! Too bad both devices are limited to lossless audio. It does not bother me since I don't own a capable speaker system and receiver anyway.

I bought the sony x700 but i am disappointed with the subtitles.
It supports the ass format (SubStation Alpha), but the style doesn't change, as if using the srt format. Subtitles are too bright.

any alternative? I would like to get the chromecast, but i read that the refresh rate is fixed
