Part 1. Reasons for ripping Blu-ray to MKV
1. Blu-ray to MKV backup can Reserve All Blu-ray Content
If you have ever encoded Blu-ray movies into MP4, AVI, or MPEG format, and been slightly frustrated with the loss of Blu-ray extra elements, then you can switch to MKV as the Blu-ray backup format. MKV is able to contain all detailed chapter information, sub-chapters, titles, multiple audio and video streams, subtitles, attachments and custom metadata.
2. MKV Container Is as Universal as MP4 with High Quality
Since MKV supports any type of video/audio tracks and subtitles inside, and is quite efficient for storage and streaming, it's widely used on video transmitting. Usually, common Blu-ray rippers can help rip a 20-50 GB Blu-ray movie to a digital file in hundreds of MB, but you will get much quality loss. Only some seasoned Blu-ray to MKV backup tools balance well on video file size and Blu-ray ripping speed.
3. Ripping Blu-ray will Remove Blu-ray Copy Protections
Blu-ray disc is equipped with a variety of protections to prevent Blu-ray content from illegal use. The most popular encryption techs include AACS, BD+, ROM-Mark, MKB, region code, etc. Blu-ray rippers can help you free your Blu-ray movies from copy protections and regional settings.

Method 3: Convert Blu-ray to MKV Free with VLC
Can VLC rip Blu-ray? Yes. The famous media player VLC also offers the ability to convert Blu-rays to MKV and various other formats. However, there are things you need to know when ripping Blu-rays to MKV using VLC. VLC doesn't support Blu-ray with copy protections. Fortunately, you can add some files to change the configuration of VLC media player so that it helps you play and rip some protected Blu-ray discs. This may be a bit complicated and requires users to download additional files to add to VLC directory. The full guide will be introduced in detail to help you convert Blu-ray to MKV with VLC.
Step 1: Go to videolan.org, download, install and run the latest version of VLC for your Windows or Mac system. Please note that you will need to download the VLC Windows 64bit version if it is a 64-bit Windows computer.
Then go to: http://vlc-bluray.whoknowsmy.name/ to download the KEYS DATABASE(KEYDB.cfg) and AACS DYNAMIC LIBRARY(libaacs.dll for Windows or libaacs.dylib for Mac). Then follow the instruction steps of the following screenshot to put them on the right place according to your computer system. Please notice that there are two different files of AACS dynamic library available at a Windows-based computer, and you should download the 32bit file for VLC 32bit, and 64bit file for VLC 64bit.
Step 2: Open VLC and insert your Blu-ray disc into Blu-ray Drive. Click Media on menu bar and a drop-down list appears. Select Convert / Save… to access to Open Media dialogue box. Besides Blu-ray disc, VLC also enables you to import DVD disc, ISO Image or VIDEO_TS folder which stores DVD contents as source for ripping to MKV, MP4, WebM, TS, etc.
Step3: Click Disc tab and check Blu-ray option and browse to import Blu-ray source to VLC. Next, set title (main title in general) and chapter you wish to rip. If you don't know which is the correct title, play the Blu-ray with VLC to find the correct title. Then click Convert / Save button.
Step 4: Click the Convert/Save button and then you'll need to select the output profile. Open the Profile dropdown menu and check if there is an MKV profile. By default, VLC will choose to rip DVDs to "Video - H.264 + MP3 (MP4)". If there is no MKV option, click the gear button next to it and under Encapsulation, choose MKV and save it.
Step 5: Choose an output destination folder and then click Start. VLC will then begin ripping Blu-rays to MKV.
Note: You can encounter many errors when you try to rip Blu-ray discs with VLC. This is because not all the commercial Blu-ray discs are supported by VLC media player so that you might encounter the problem from time to time. VLC can only deal with discs which its library has the corresponding AACS keys, yet the AACS and BD+ DRM libraries and keys won't ship with the Blu-ray discs, as their publishers seem to take everyone as a pirate, even you already spend money just for personnel movie enjoyment. And that's why the professional Blu-ray rippers exist on the market.
Method 4: Transcode Unprotected Blu-ray to MKV Free with Handbrake
Handbrake is a popular yet free video/DVD transcoder and it can be used to rip Blu-ray to MKV on Windows, Mac, and Linux. Of course, you're required to make sure that your Blu-ray is not copyright protected, for HandBrake converts neither encrypted physical Blu-ray Disc nor decrypted commercial Blu-ray movies in BDMV file structure.
Therefore, if you have some homemade or burned Blu-ray discs, you can use Handbrake to convert them to MKV or MP4 format. For store-bought commercial Blu-ray discs, you'll probably need a Blu-ray decrypter to remove the copy protection first. Now let's walk you through how to convert Blu-ray to MKV with Handbrake.
Step 1. Download and install HandBrake. Launch it when you finish installation.
Step 2. Insert the non-protected Blu-ray disc to your Blu-ray drive and then click "Open Source" to load the Blu-ray content. The main title will be selected for homemade Blu-rays by default. If not, you can manually select the right title from the Title dropdown box.
Step 3. Click Preset > Matroska, and then choose a MKV format.
Step 4. Hit Start Encode button to begin ripping Blu-ray to MKV. Note: HandBrake will decode the Blu-ray and re-encode the video into MKV in H264, H265, or other codecs, during which quality loss will happen.
The range of abilities of these Blu-ray to MKV converters is fairly broad. On the unsurpassable decryption end you find DumboFab Blu-ray Ripper, which goes beyond all the rivals in our test when loading Blu-rays and DVDs, either old or new.
