Perhaps you don’t quite understand me because of the translator, but you caught the essence, different frame sizes, imax scenes and ordinary ones. If the blu-ray and streaming versions were used, everything is identical in them, the scenes change exactly, what is this procedure for?

Because the itunes DV source is cropped and doesnt have L5 metadata.

It doesn't matter for HDMI devices though, L5 is ignored and DV tone mapping is always applied to the whole image, letterbox included.
only the LG TVs internal player use that metadata.(I dont know about the other TVs brand)

I made a hybrid of uhd hdr and web-dl MA, there is a full frame, therefore, these manipulations are useless, if I understand you correctly.

In a few hours when I get home.

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

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

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.

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"

Hi, RESET_9999.

ffmpeg there are commands dvh1? I didn't find the command dvh1 only there is hvc1 и hev1, i need to dvh1. mp4box dvh1 great, but iPhone and iPad subtitles don't work, ffmpeg subtitles work.
