As a premise: Only MKV/DV`s with Dolby Vision Version conforming to 1.0 dvhe.07.06 BL+EL+RPU Blu-ray can be processed!!! No KMV/DV (source web rip) which do not meet this specification!!! Therefore, you should scan the file with BDinfo or Mediainfo to check compatibility. Required software: MediaInfo https://mediaarea.net/de/MediaInfo Dolby Vision MKV Extractor (Team QfG) Vers. 01 beta (Attached to this thread) TsMuxer https://github.com/justdan96/tsMuxer/releases Scan with MediaInfo: The next preparation step is the creation of a folder (DVMKV_Extractor) which contains the following by uncompressing the attached rar file: Copy your MKV/DV file to this folder and then drag it on the DVMKV_Exractor.exe file. The program will start automatically. A folder with the name of the MKV/DV file will be created. Here you can see the progress of the extraction which is done automatically: Extractions of the Video Layer (BL), DV Layer (EL) and the RPU Meta data will be done sequentially. You will need the files BL and EL for future steps. Please make sure that you have available storage space that is at least twice the size of your MKV/DV file!!!! After finishing you should have these files in the folder: The RPU.bin will not be needed and can be deleted. The next step is he extraction of the sound track(s) and the subtitles from your MKV/DV file with TsMuxer. By this step you have finally all files available to create the ISO / DV file. Start TsMuxer and open the MKV/DV file. Check all items with the exception of the video file and demux everything to the folder that contains the BL.hevc and EL.hevc files.
