Hi, I've just found an interesting suggestion of Google to convert HDR to SDR using a LUT: https://developers.google.com/media/vp9/hdr-encoding/ Search the page for: "Converting HDR to SDR" They do it for VP9, but it can easily be adjusted to AVC/HEVC. To be able to let it run, you must...

Should work with ffmpeg. Are the audio files inside a m2ts file and do you know that file? If so, then try e.g.: ffmpeg -i D:\BDMV\STREAM\00023.m2ts -vn -dn -c:a flac -y audio.flac This should select the best audio stream available. If you want to extract a specific audio track, e.g. the first...

Hi, last year I've tried around a while with Intel qsv and Nvidia nvenc. I've then choosen nvenc because it was faster and more reliable. But there's one thing you can read everywhere and you should keep in mind when it comes to GPU acceleration: Quality will suffer a lot or you must accept a...

Hm, it's not clear to me, whether you want to copy or convert the audio track. In my reply I'll assume now that you want to copy it. You would like to improve the overall quality of the encodes? Then I'd suggest to use x265 (HEVC) instead of x264 (AVC) at the same bitrate. This will improve...

Hi, you don't write how many audio tracks you have in the file AC_S01E01.mkv. In my reply I assume it's one audio track only. If you want to fit 4 videos of 1 hour on one BD25, then each should get a size of 6 GB. This would lead to a bitrate of 14.3 Mbits. As you must consider the size of...

Thank you for the hint with respect to the disc.inf file. That will save a lot of my time when processing the next multiple-m2ts-disc :) As said my normal procedure is similar as yours. I copy the m2ts file to my hard disc and after that I look into it with the help of MediaInfo to see if there...

I've just described that at https://forum.redfox.bz/threads/uhd-backup-wie-und-womit.74354/page-12#post-489369 Unfortunately that post is in german language, so I will try to repeat the same in English. First you have to find the appropriate playlist. To do so I sort the mpls-files in the...

Hi, a nice ffmpeg-suggestion to convert 10bit UHD HDR to SDR with HDR-like colours can be found at https://stevens.li/guides/video/converting-hdr-to-sdr-with-ffmpeg/ I've worked out an example for the UHD disc Oblivion. In that example the 3840 * 2160 HEVC HDR source is converted to 1920 *...

Hm, that's interesting. Are you sure it's John Wick 2, which is consisting of multiple m2ts files? I do encoding in a similar way as you do. I.e.: I copy the respective m2ts file to my hard disc and then I use ffmepg on CLI (instead of handbrake) to encode it. I've ripped and encoded John...
