How to keep Dolby Digital 5.1/Dolby True HD 7.1 audio when ripping Blu-ray movies?
Step 1. Hook up an external BD drive with my desktop (if there is not an internal one), and place a Blu-ray Disc into the BD drive.
Step 2. Run Pavtube ByteCopy software and click the "Load file(s)" icon to import movie files from Blu-ray Disc.
Step 3. In the dropdown list of Format menu, you can find several MKV options for output. Here we recommend "Lossless/encoded Multi-track MKV (* mkv)" under "Multi-track Video" catalogue. Because it will save multiple video, audio and subtitle tracks form original Blu-ray in output MKV and you won't suffer any quality loss.
Note: Make sure the original BD disc does contain Dolby TrueHD audio, otherwise you still can't get Dolby TrueHD 7.1 audio saved.
Step 4. You can check the audios you want to keep and uncheck the audios you don't need. It all depends on your own choices.
Note: Not every AV receiver/amplifier can decode Dolby TrueHD and DTS-MA audio, but most of them support Dolby Digital, i.e., AC-3 5.1 audio codec. When ripping Blu-ray Disc for playing back with PC and HD media players, better check the supported codec of your device first to set a best fit for your player.
So to transode blu-ray audio streams into Dolby Digital 5.1 tracks, you can check "Encode" and get a encoded mkv file.
Step 5. Click the "Convert" button to start ripping the Blu-ray movie to MKV file. After conversion I click "Browse Export Path" and get an MKV file.
Pavtube ByteCopy extracts the main movie with all subtitles from disc and seals the contents with riginal Dolby Digital 5.1 and TrueHD 7.1 audio saved into MKV container which means ripping Blu-ray lossless.
That's it! Now you will have a great high definition Blu-ray with great audio experience!.
