How bad it is that we speak different languages and we don’t understand each other well((((
Used on the built-in LG player, movies anywhere streaming service has a full frame, not cropped like amazon or itunes, I recognize or you will understand me this time)
there is no MA Profile 5 available online on torrent/scene... the only DV source is iTunes.
Even if MA P5 DV was available, all their encodes have incorrect Level 5 metadata just like itunes.

Metadata was extracted by me from MA hybrid release (8 profile, full frame) and injected into uhd hdr
Even if MA P5 DV was available, all their encodes have incorrect Level 5 metadata just like itunes.
What does it mean not faithful and why release such a thing at all? ...
Where can I read in detail and in an understandable language about the levels?

that ma p8 release use DV meta from iTunes...
Easy to tell because all the iTunes web-dl are missing level 4 metadata.

Studios can be a bunch of amateur sometimes, nothing new here. We often get much better quality through piracy.

You can use the hdr10plus_tool if you cant wait for me...
Code: Select all
hdr10plus_tool.exe remove input.hevc -o hdr10plus_removed_output.hevc
After running through this utility, the frame rate changes from 23.976 to 25.000, this should not be! I suppose this is due to incomplete resolution, how to solve this problem?

appletv / iTunes web-dl I guess?
This is due to Apple's incompetence. Most of their encodes are missing the frame rate bitstream information and if you don't specify it before muxing in mkvtoolnix, the output will be 25fps after using the dovi_tool/hdr10plus_tool.
You could try to write a proper framerate bitstream with eac3to.exe but it doesn't work all the time.

RESET_9999, уes exactly Apple TV. The new script that I expect from you is taught to do this automatically to avoid similar problems?
P.S. In manual mode, I got rid of the problem

Yes, the script takes care of specifying the proper frame rate before muxing to MKV or TS but it doesn't fix it at the bitstream level like eac3to.exe or ffmpeg can do.
Code: Select all
eac3to.exe "D:\input.mkv" 1: "D:\output.h265" -23.976 -changeto23.976
Code: Select all
ffmpeg.exe -vsync drop -i input.mkv -c copy -bsf:v hevc_metadata=tick_rate=24000/1001:num_ticks_poc_diff_one=1 "output.hevc"

RESET_9999, thanks for the correction in DoVi_Scripts_1.9.0, now the 6-1-1 works as expected, of course, you need to pre-prepare the video as you wrote with eac3to or ffmpeg, thanks

@RESET_9999 is it possible to convert SDR video to HDR using the script or DaVinci?

The problem of iPhone and iPad subtitles should be solved by mp4box.

RESET_9999, I understand that maybe the question is not at the right address, but I'll ask if you know. There is a problem that could not be solved, I understand that this is some kind of limitation of the LG operating system, if you play DV mp4 movies over the network (DLNA or NAS) with a lot of subtitle tracks, then switching subtitles is not available, at the same time if you run the same movie in mkv over the network, then subtitles can be switched as when connected via usb

You can try
Code: Select all
mp4box -add dv.hevc -add atmos.eac3 -add sub.srt:hdlr=sbtl:lang=eng -new dvh1.atmos.engsub.mp4
Or you can first put an mov_text sub into a mp4 container
Code: Select all
ffmpeg -i sub.srt -c:s mov_text -metadata:s language=eng sub.mp4
And then
Code: Select all
mp4box -add dv.hevc -add atmos.eac3 -add sub.mp4 -new dvh1.atmos.engsub.mp4

subtitles no.
ffmpeg -i sub.srt -c:s mov_text -metadata:s language=eng sub.mp4
through mp4box -add dv.hevc -add atmos.eac3 -add sub.mp4 -new dvh1.atmos.engsub.mp4
