When it comes to backing up a Blu-ray disc, you may want to remux the file from the Blu-ray disc directly into a MKV format container for uncompressed rip. After re-muxing, you can this the MKV file as input for another program, use any player to watch it in about any platform or just store it in your hard drive as a backup.


In this article, we will share with you two methods for remuxing a Blu-ray disc to MKV. One is free, another is paid. The free method is complex cause you need to use three tools to rip a Blu-ray disc, demux it and then remux it to mkv format separately. If you don't mind that the software needs to be paid, the process of remuxing Blu-ray to MKV will be much easier. Both the two ways you will get a huge, but unprotected, easy to use and store mkv file that contains the exact video and audio streams as your Blu-ray disc quality and size-wise. Now, you can remux Blu-ray disc to MKV files using your preferred method.

Method 1: Free rip a Blu-ray disc and remux it to MKV

To freely rip Blu-ray disc and remux it to MKV file, you need the below three software. You can download it from clicking the links.

tsMuxeR: It is a transport stream muxer that supports most HD input formats such as H.264/VC-1 and E-AC3/DTS-HD, and can output to Blu-ray's M2TS.

BDInfo: This software was designed to collect video and audio technical specifications from Blu-ray movie discs, including disc size, playlist contents, video, audio, subtitle and graphics stream codec details and bitrates.

mkvtoolnix: It is a set of tools to create, alter, split, join and inspect Matroska files(mkv). With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files.

Guide to Re-muxing Blu-ray to MKV Freely

Step 1: Before you start remuxing Blu-ray to MKV, you need an unlocking software to circumvent the Blu-ray's protection. You can use a Blu-ray ripping tool to remove Blu-ray protection.

Step 2: Now, open up BDInfo. We can determine which file is the main title with this application. Click Browse to select the BDMV folder in your Blu-ray disc and then check out which playlist contains the movie, obviously the one with the biggest length and check its name. Now, leave BDInfo open and run tsMuxeR.


Step 3: Add (1) the playlist file that we have already found in BDInfo. tsMuxeR will automatically load all the m2ts files assosiated with it. Once the main movie is loaded and ready for extraction, select the main video track, the audio that you want to keep and any subtitles (2) you may need later on. Then set output to Demux (3) and after you set the location of the output files, click Start demuxing(4).


Step 4: tsMuxeR will now copy the tracks you have selected to your hard drive. This process will take from about 45 to 90 minutes, depending on the speed of your Blu-ray drive and the size of the disc. When it is done, click OK and close tsMuxeR. Next step is to create our mkv file, so run mkvmerge GUI (named mmg.exe in the archive you have downloaded).


Step 5: Now, run mkvmerge GUI and then click add (1) and and select all the files that we demuxed before (2). You can also add subtitles in Blu-ray's .sup format. Now we need to set some options. Select the video track (3), set the language (4) and then click the Format specific options (5) tab.


Step 6: Here you need to add the FPS value exactly as the one you wrote down at Step 2.


Step 7: Feel free to add the correct language to any other audio or subtitle tracks you may have and when you are ready Browse (1) to set the output filename and click Start muxing (2) in order to start the process.


Step 8: That's it. A few minutes later you will have an mkv file containing the exact video and audio streams of your Blu-ray disc. You should delete all the files tsMuxeR created as you no longer need them. You can now test your mkv file using any player that supports that format and then use it as you please.


Method 2: Easier way to remux Blu-ray to MKV

This way will be much easier than the method 1 to remux Blu-ray to MKV. And you can finish the remuxing process with only one software called LosslessCopy (available for Windows and Mac users). The program can decrypt Blu-ray to bypass the protection and remux Blu-ray to MKV and other containers like AVI, MP4, MPG, TS, etc without any picture and sound quality loss. Remuxing is quick and retains the full quality of the original Blu-ray disc but the resulting files can be quite large. So you also can rip Blu-ray to MKV, AVI, MP4, etc format with adjusting video and audio codec, bitrate, resolution to change the output video size. Of course, if you reduce the video resolution and bitrate to reduce output video size, you have to prerare the quality loss. In the remux process, you can keep your Dolby Truehd DTS Ma, Dolby DTS 7.1/5.1 audio in original Blu-ray disc and multi-track subtitles, chapter makers.
