yeah, with the eye there is no difference. i also say that before in this thread. but i'm not sure if that is enough? what happens on the background in technical way? i think we shall only know with professional tools...
I agree..

This may not be a professional tool but I think if there was a difference in colors and brightness, my camera would capture it.
see this comparison: https://screenshotcomparison.com/comparison/6043

I did this comparison with many movies and never spotted any difference.

I appreciate you're work for that.

Good evening people.
I'm trying to figure out if it is possible to convert (without quality loss) a FEL movie to MEL. I have some ideas about it and this is a first try.
In THIS archive you will find two files: the original file is the FEL one (generated starting from the ISO uploaded HERE by @RESET_9999), the MEL file was obtained by modifying the first.

If you feel like it, try both files. Personally I am interested in the tests carried out on devices that have proved capable of playing MEL files with profile 7 but not FEL files (Fire Stick 4K, some Android TVs, etc ...). With these latest devices the desired result should be:
FEL file -> HDR (or unplayable)
MEL file -> DV.

Please, in your feedback obviously indicate the outcome, the device and the player used (if you can, also use my version of ExoPlayer).

Thank you

thank you yusesope for the great work as always.

I'll check out the files tonight.

I have an LG C8.

The LG internal player freezes a lot with both FEL and MEL files, for some reason.

On the Fire TV Stick 4K (your ExoPlayer):
FEL file -> DV, black screen.
MEL file -> DV, plays fine.

:D

Fantastic work yusesope! Here are my observations-

Both files say unsupported file format in the internal media player.

FEL plays with HDR through Kodi+your latest exoplayer.

MEL plays and triggers DV through Kodi+your lastest exoplayer.

I'm playing these directly on my Android TV. (A cheap Indian brand, VU Cinema TV 50" with Dolby Vision).

Looking forward to a detailed method as I'd love to convert all my FEL titles into this format so I can play them directly on the TV.

Thank you for your time!
The results are what I was hoping for :D but It's too early to claim victory :!: !
The "final test" must be conducted on a full movie and not on a 60sec segment.
I hope cheaper devices don't run out of RAM due to a too large buffer.
We'll see.

There is currently no detailed method, just lines of code that only make sense to me...
In the next days/weeks I will release the 0.0.4 BETA version of my tool (I will update my original post HERE as always) so those interested can do all the tests they want and help me fix any bugs.

In the meantime maybe I'll write some technical posts to start a discussion and see if anyone has any ideas to validate/improve my logic.

Hi, i probably know the answe to this, but is there a way to reverse the DoVi created mp4?

For example de-mux the mp4 file and make a working MKV out of it?

Thank you.

It plays dual layer dual track in the form of mkv (dual layer single track) via kodi + Yusesope Exoplayer and .ts profile 4 (using Yusesope tool)

I've had success creating Dolby Vision + Lossless Audio TS files with dozens of movies (using eac3to + Yusescope's tool + tsMuxer 04.06) but I have run into an issue with Braveheart that has me stumped. All of the audio tracks, including the TrueHD Atmos track, require a delay of 2,169ms in order to sync up with the video.
    When I create the .TS file in tsMuxer with the audio delay set to 2,169ms, my 2019 Shield Pro reverts to HDR and transcodes down to DD+.
      When I create the .TS file in tsMuxer with the audio delay set to zero, it plays in Dolby Vision & TrueHD Atmos on my Shield Pro but with the audio clearly a couple seconds ahead of the video.
      Has anyone encountered this issue with other movies?
      Are there any solutions to tackle this, such as removing the first 2,169ms of the video to make them sync up, or any way to add 2,169ms to the beginning of the .thd+ac3 file?

          when you're extracting the bl and el files with eac3to, did you notice any errors? when there's an a/v sync issue after remuxing, it's possible that there may be errors in the original video layers.

              No errors during the extraction and the issue appears to exist before that point. When I pull the original M2TS / MPLS files into eac3to and tsMuxer they already acknowledge the required delay:
              eact3to:
              1: Chapters, 22 chapters
              2: h265/HEVC, 2160p24 /1.001 (16:9), 10 bits
              3: h265/HEVC, 1080p24 /1.001 (16:9), 10 bits - Dolby Vision Enhancement Layer
              4: TrueHD/AC3 (Atmos), 7.1 channels, 48kHz, 2168ms
              (embedded: AC3 EX, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB)
              5: AC3, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB, 2168ms
              6: AC3, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB, 2168ms
              7: AC3, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB, 2168ms
              8: AC3 Surround, 2.0 channels, 224kbps, 48kHz, dialnorm: -27dB, 2168ms
              9: Subtitle (PGS)
              10: Subtitle (PGS)
              11: Subtitle (PGS)
              12: Subtitle (PGS)

              tsMuxer:
              Automatically sets the delay on all audio files to 2,169ms when imported.
