How to Convert 3D Blu-ray to 2D Video: DVDFab 3D Converter Guide

Most people who own 3D Blu-ray discs run into the same two problems: their TV no longer supports active 3D, or they want to watch the movie on a device that never did — a tablet, a VR headset, or a phone. Converting the disc to a standard video file solves both. I tested DVDFab Blu-ray Ripper's 3D conversion workflow across both scenarios and laid out the full process below.

DVDFab Blu-ray Ripper handles 3D Blu-ray discs, ISO images, and folders. It reads the MVC (Multiview Video Coding) layer that stores the depth data on every 3D disc, then lets you output either a flat 2D file for regular playback or a side-by-side / top-bottom 3D file for VR headsets and supported displays. The four steps below cover both paths.

DVDFab Blu-ray Ripper

Convert 3D Blu-ray disc/ISO/folder into portable, highly compatible digital video formats in either 2D or customized 3D.

Features of this 3D to 2D video converter:

• Converts 3D Blu-ray to 1000+ 2D/3D video formats.
• Also enables to transfer 2D Blu-rays to 3D videos.
• Selects Blu-ray titles, chapters, audio, and subtitles.
• The multi-task mode enables you to batch convert multiple 3D Blu-rays.
• The GPU acceleration technology makes the conversion faster.

Steps to Convert 3D Blu-ray to 2D Video with DVDFab

Step 1: Download DVDFab and Load Your 3D Blu-ray

Open DVDFab and navigate to the Ripper module. If your source is a physical disc, insert it into a Blu-ray-capable optical drive and click Add Source to load it. If you are working with an ISO image or a disc folder ripped to your hard drive, drag and drop it directly into the main window instead.

DVDFab will scan the disc and populate the title list. For most 3D Blu-rays, the main feature is the longest title and is selected by default.

Step 2: Select a 3D or 2D Video Profile for the Output

After loading, the audio tracks and subtitles can be adjusted directly on the main screen. Click Choose Other Profile to open the format library.

DVDFab automatically reads both the standard AVC layer and the MVC depth layer from the disc. You do not need to manually select the 3D video track. What you choose here is the output format:

• For 2D output (phones, tablets, standard TVs): select a profile under Format or Device — MP4 and MKV are the most compatible choices.
• For 3D output (VR headsets, 3D displays): select a profile under 3D Format or 3D Device. Side-by-side (SBS) MP4 or MKV is a common choice for VR players, and a 3D Blu-ray to SBS 3D MKV/MP4 conversion is useful when the player expects both views inside a conventional video frame.

A regular TV needs 2D output. Headsets, XREAL glasses, Vision Pro apps, and 3D projectors need a layout their player explicitly supports. MVC is for players that decode the MVC extension; Half-SBS generally favors compatibility and smaller files, while Full-SBS preserves more per-eye detail but has narrower support.

Step 3: Customize and Edit Your Blu-ray

Click Advanced Settings to adjust video and audio parameters. If the output profile is a 3D format, a 3D tab appears with three layout options:

• Side-by-side (SBS): left and right eye frames placed horizontally. This is the standard format for most VR headsets and 3D-capable media players.
• Top/bottom (Over-Under): left and right eye frames stacked vertically. Supported by some displays and VR apps as an alternative to SBS.
• Anaglyph: encodes depth as color channels (red-cyan). Works on any standard display with red-cyan glasses, but with reduced color accuracy.

Click Video Edit to trim, crop, merge clips, or add subtitles and watermarks before encoding. Note that video editing is optional and will not affect the 3D output format you selected.

Step 4: Start the 3D Blu-ray Conversion

Choose a destination folder and click Start to begin. DVDFab displays real-time progress, estimated completion time, and a preview window during conversion.

Conversion time and file size depend on the CPU, GPU, memory, optical-drive performance, source length, output profile, and encoder settings; GPU acceleration can reduce encoding time on supported hardware.

You can adjust the bitrate in Advanced Settings to trade off file size against image quality. I treat a short preview as the most reliable checkpoint because it can reveal a layout or audio mismatch before a full encode is complete.

Fix Flat, Stretched, or Silent 3D Output

A correctly encoded file can still look flat, stretched, or silent when the 3D mode, aspect-ratio handling, or audio path does not match the player. Check these items before converting the rest of a collection.

• Flat or 2D-only playback: Confirm that you selected 2D MP4 or MKV for a regular display, or a 3D layout for a headset, glasses, projector, or 3D player. An MVC MKV requires an MVC-capable player; an ordinary video player may show only one view.
• Squished or stretched image: Select the file's SBS or TAB mode in the player and disable automatic 16:9 conversion if it changes the frame shape. Match Half-SBS or Full-SBS to the layout expected by the app.
• Small playback window: Check the app's 3D projection, aspect-ratio, and screen-size settings, then preview the same file in a player that supports the selected layout.
• Missing audio: Select an audio track compatible with the player, or use passthrough only when the player supports it. A short preview can confirm sound before a full encode.
• Full-SBS rejected: Switch to Half-SBS or TAB if the player or display does not accept Full-SBS. Full-SBS support is narrower than Half-SBS on some playback setups.

Before starting a long batch, play a short preview on the target device and confirm the picture shape, 3D depth, subtitles, and audio. I use this check because a correctly created file still depends on the player's mode and codec support.

Conclusion

The right output profile depends on what you plan to do with the file. For standard playback on phones, tablets, and non-3D TVs, a 2D MP4 or MKV gives the most compatible result with a manageable file size. For VR headsets or a 3D display, an SBS output preserves the depth experience, but expect larger files and longer encode times.

DVDFab handles the MVC layer automatically, which removes the manual track-selection step that free tools like MakeMKV require. If you are already comfortable with a command-line workflow, that route works. If you want a single-application process with format presets for specific devices, DVDFab covers that without additional configuration.
