A practical solution is to convert 3D Blu-rays to 3D MKV videos. MKV (Matroska) is a versatile container format that allows you to keep multiple video streams, audio tracks, subtitles, and chapter markers in one file. Better yet, when you rip and encode correctly, you can preserve the 3D effect with minimal loss of quality.

In this guide, we’ll cover two main parts:

     1. How to convert a 3D Blu-ray folder to 3D MKV using BD3D2MK3D.

     2. How to burn MKV videos back to Blu-ray using Yuhan Blu-ray Creator.

Let’s dive in.

Part 1. Convert a 3D Blu-ray Folder to 3D MKV Using BD3D2MK3D

Before we jump into the step-by-step process, let’s first understand what 3D Blu-rays are and why BD3D2MK3D is the best tool for this task.

What Are 3D Blu-rays?

A standard Blu-ray disc stores high-definition video in AVC (H.264) format. A 3D Blu-ray disc, however, uses an advanced encoding method called MVC (Multiview Video Coding), which builds on AVC to store an additional view for the left and right eyes. This allows compatible Blu-ray players and displays to render full stereoscopic 3D video.

The challenge is that most software players and media devices cannot directly handle MVC streams. This is where BD3D2MK3D comes into play.

Why Use BD3D2MK3D?

BD3D2MK3D is a specialized GUI tool designed to convert 3D Blu-rays into 3D MKV videos. It supports multiple 3D output formats, including:

• Full or Half Side by Side (SBS)
• Top and Bottom (TAB/OU)
• Frame Sequential (FS)

It uses x264 (H.264) or x265 (H.265/HEVC) for encoding, giving you flexibility in balancing quality and file size. Since version 0.87, it also supports lossless 3D AVC+MVC files generated by MakeMKV, meaning you can retain maximum quality if you want.

Step-by-Step Guide: Convert 3D Blu-ray to 3D MKV

Step 1: Decrypt the 3D Blu-ray Disc with MakeMKV

Commercial Blu-ray discs are encrypted with AACS protection. To use BD3D2MK3D, you first need to decrypt the disc.

• Download and install MakeMKV.
• Insert your 3D Blu-ray disc.
• Open MakeMKV, and click the disc icon to scan.
• Save the decrypted files to a Blu-ray folder on your hard drive.

This creates a full backup that BD3D2MK3D can read.

Step 2: Download BD3D2MK3D

• Visit the official page: BD3D2MK3D on VideoHelp.
• Download the compressed ZIP file.
• Extract it to a folder. No installation is required—it’s portable software.

Step 3: Install AviSynth+

BD3D2MK3D relies on AviSynth scripts to process video frames.

• Download AviSynth+ here: AviSynth+ on VideoHelp.
• Install it on your system before running BD3D2MK3D.

Step 4: Load the 3D Blu-ray

• Open BD3D2MK3D.
• Click “Open Blu-ray 3D”.
• Browse and select the decrypted Blu-ray folder.

The program will detect the main movie and related streams.

Step 5: Select Streams

Choose the video stream, audio tracks, and subtitles you want in the final MKV. You can include multiple languages and forced subtitles if needed.

Step 6: Add Metadata

Set the title, tags (director, producer, year), and other metadata. This helps organize your video library.

Step 7: Set Cover Art

BD3D2MK3D allows you to embed cover artwork into the MKV file. This is optional but useful for media servers like Plex, Kodi, or Emby.

Step 8: Choose 3D Format and Output Folder

Select your preferred 3D type:

• Side by Side (SBS) – Best for most TVs and VR headsets.
• Top & Bottom (TAB) – Alternative for some players.
• Frame Sequential (FS) – Ideal if your playback device supports it.

Set the Project Folder and Output Folder, then click “Do it”.

Note: This step triggers the preparation process and generates the necessary scripts. Encoding can take hours depending on your CPU power.

Step 9: Run the Encoding Script

In your project folder, find the file named:

__ENCODE_3D_LAUNCHER.cmd

Double-click it to start the encoding.

When the encoding finishes, the final 3D MKV file will appear in your output directory.

Pros and Cons of BD3D2MK3D

✅ Advantages

• Supports multiple 3D formats.
• Keeps original audio and subtitles.
• Works with MakeMKV lossless files.
• Free and portable.

❌ Disadvantages

• Encoding is time-consuming.
• Interface feels technical for beginners.
• Requires AviSynth+ installation.

Still, it’s one of the most powerful free solutions available for 3D Blu-ray conversions.

Part 2. How to Burn MKV Videos to Blu-ray

After converting your 3D Blu-ray to MKV, you may want to back it up to a physical Blu-ray disc for playback on your home theater system. For this task, you need a professional Blu-ray authoring tool.

Why Burn MKV to Blu-ray?
