Dolby Vision now possible through MP4 Mux.

1- I played a 1080p24 file and Plex matched it to 24Hz, confirmed with System X-Ray. HDMI set to 24Hz.
My display settings are set to Auto.

2- Played a 720p25 file and it is sent as 720p50 to the TV.

Are you sure you're matching the resolution as well in Plex?

3- I'm pretty sure not setting to Auto makes the OS hide the different refresh rate modes, it was the same on the 2018 with Kodi at least.

Netflix logged me out so I don't want to bother trying it, but I'm pretty sure it did 2160p.

1- will test another file, but the one I tried played in 23.976fps according to my vertex.
2- didn't try 25fps content (not sure if I even have some) but yes, both firestick and plex settings have the frame rate match on. Resolution match, I tried both but will try again, I'm not sure
3- yep, once you're not on ''auto'', framerate match becomes greyed out.

The Android Plex app has two settings, one for the refresh rate, the other for the resolution.
At least for me.

yeah sorry I misread your post.
Yes, I think I tried the resolution match on and off. but will try again, not 100% sure

ok so I tried with plex resolution match on ... this makes the TV switch to 720p for 720p video but it stays in 1080p for 4k videos ...
So I guess the right setting is ''off '' but still no 4k for non-4k video if the firestick display setting is ''auto 4k max''

Tried another 24fps video and still got 23.976
tried 29.970fps video and got 60fps.

I remembered I did post about this before: https://www.avsforum.com/threads/offici ... t-61099898
So it's weird for it not to upscale at all for you..

Although I can't remember if I did that test on the new 4K Max.

I have a question regarding encoding a file to 1920x1080p and add the Dolby Vision later. Somehow, I don't get the right file after RPU insertion.

I have encoded a Game of Thrones Episode (4K REMUX, which is Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU). I encoded it without cropping, (which I do for every encode, also movies, I just resize it from 3840x2160 to 1920x1080).

It got me an 1080p episode, which is HDR10. I used the following command to change the .mkv file to hevc:

ffmpeg -y -i GOT.S01E01.mkv -an -c:v copy -f hevc GOT.S01E01.hevc

After this, I use the command to extract the RPU from the HEVC with mode 2:

dovi_tool -m 2 extract-rpu GOT.S01E01.hevc, which gives me an RPU.bin, which, I think should be converted to profile 8.

After this, I use the ffmpeg command to change the re-encoded file from .mkv file to hevc.file. I then usethe following command to inject the RPU into the re-encoded HEVC.file:

dovi_tool inject-rpu -i GOT.S01E01.HDR.hevc --rpu-in RPU.bin -o injected_output.hevc

But somehow, I doesn't work for me. It keeps begin SMPTE 2086, HDR10. Dolby Vision won't be visible in the hevc output file. When I mux the hevc.file to .mkv, then it still is only HDR10, and not Dolby Vision.

What is the part where I screw up? I'm doing it somewhere, but I just can't put my finger on it. Or is it a cropping thing? Some help with this would be very appreciated!

Try running the muxed mkv through MakeMKV

Makemkv is just adding the dvhe flag, in profile 7 and 8 you can do this quickly with a hex editor, it is in the linked to guide on the previous page.

I'm facing a new problem with a movie: Bumblebee (2018).

I encoded the movie to 1920x1080p, the movie itself is DV 07.06, so I just extract the RPU (Shield Pro, so it does play). Somehow, when injected into the encode, and afterwards to .mkv and then makemkv, it is DV 04, which it sees as ''SDR''. I don't know why this is happening? When I extract the RPU with mode 2, I will get a DV 08.03 file. If I use mode 0, I also get DV 04. Does anyone know why this is happening with this movie?

Can you provide the RPU file?
It would be weird for the profile to be detected as 4.

I have uploaded the RPU.

@quietvoid
When I extract RPU from the Enhancement Layer, the resulting RPU length does not match the video length.
Mismatched lengths: video 163840, RPU 128978
This error has occurred in one movie so far.
I can send the sample EL.hevc file if you need via PM.

The EL was probably cut off somehow.
In the past tsMuxer did that, you should try getting it directly from the m2ts with ffmpeg.
I don't need the sample because it wouldn't be very useful unless you're 100% sure it's complete.

Thanks. I can't reproduce the profile 4 issue with MakeMKV.

Regardless of if the RPU is added with x265 or injected, it always shows profile 7: Codec: MpegH HEVC Main10@L5.1 (dvhe.07.00 BL+RPU)
MKVToolNix (v62) also adds the correct block: Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible

By the way, you shouldn't be reencoding unless the RPU is profile 8.
Because the EL would probably be out of sync, and might not even work with 1080p base video.
And keeping a profile 7 RPU makes no sense without the EL.

Thanks for your reply.

What do you mean with the reencoding? Wouldn't it be possible to encode the DV 07.06-> change profile to 08 and inject it back?

As for the profile 7 RPU without the EL, I think I have to check the differences between profiles. What would be ''better'' to use? Convert to profile 08? Since that did work with Bumblebee (somehow 08.03, not 08.06). Is there a difference between 08.03 / 08.06? Another forummer told me I could change the HEX using the HEX-editor to change the profile from 08.03 to 08.06, but I don't know how to use/do that. Any advice what would work best?

If you're reencoding just use x265 and the RPU directly: https://x265.readthedocs.io/en/master/c ... vision-rpu
You should just convert to profile 8.

8.03 and 8.06 is just a level difference, because the 03 is 1080p while 06 is 2160p.
With most devices, there's no difference between profile 7 and profile 8, especially if you use MKV.

The hex editing thing only applies for MP4s, you shouldn't have to do anything if you use MKVToolNix v58+.
MakeMKV isn't necesary either, for encodes without an EL.

Thanks for your quick reply! So the 08.03 should be fine now?

I use Ripbotx264 for for the encoding. After I use ffmpeg to get the .mkv -> hevc, and extract the RPU (will extract with mode 2 from now on). Then i change the encoded file from .mkv -> hevc and inject the RPU into the encode. After this I mux to .mkv. Then it just says 'HDR10''. I really have to mux the .mkv file through Makemkv to make the DV 08.03 visible.
