How to Convert 3D Blu-rays for Apple Vision Pro (Step-by-Step Guide)

So you've got a shelf full of 3D Blu-rays collecting dust. Maybe it's Avatar, Gravity, or that copy of Pacific Rim that looked incredible in the theater. And now you have an Apple Vision Pro sitting on your desk. You'd think there'd be an obvious way to watch your 3D Blu-ray collection on Vision Pro, right?

There isn't. At least, not out of the box. Apple Vision Pro plays spatial video in a format called MV-HEVC (Multiview High Efficiency Video Coding). Your 3D Blu-rays use a completely different format called MVC (Multiview Video Coding). They're not compatible. They're not directly compatible.

But here's the good news: you absolutely can convert 3D Blu-ray to Apple Vision Pro spatial video. You just need the right tool and an MKV or M2TS file of your 3D content. Let's walk through how it works.

What You'll Need

• An MKV or M2TS file — Your 3D Blu-ray content in a standard container format with the MVC (Multiview Video Coding) 3D track intact. These files typically contain both the base view and dependent view that make up the full 3D experience.
• SpaceRay — A Mac app that converts 3D MKV/M2TS files into MV-HEVC spatial video for Apple Vision Pro (or Side-by-Side 3D for Quest 3).
• A Mac with Apple Silicon — Recommended for hardware-accelerated encoding. Intel Macs work too, but they'll be significantly slower.

Step 1: Get Your 3D Content Into a File

SpaceRay works with MKV and M2TS files that contain 3D Blu-ray content. If you already have your movies in one of these formats with the MVC 3D track, you're good to go — skip straight to Step 2.

If you're starting from a physical disc, you'll need to get the content into a file first. There are various tools available for extracting video from Blu-ray discs — a quick search will point you in the right direction. The key thing is to make sure you select the 3D version (the MVC track), not the standard 2D version. 3D Blu-ray discs contain both, and the 3D track will typically be the larger one.

Step 2: Convert with SpaceRay

This is where the magic happens — turning your MVC-encoded file into MV-HEVC spatial video that Apple Vision Pro can play natively. Open SpaceRay and drag your MKV or M2TS file into the window. SpaceRay automatically detects the 3D format and shows you a preview.

Under the hood, SpaceRay is doing something pretty sophisticated. Blu-ray 3D stores video as two layers: a base view (the left eye, essentially a normal 2D video) and a dependent view (the right eye, stored as a delta from the base). SpaceRay decodes both MVC streams, reconstructs the full stereo pair, and re-encodes everything as MV-HEVC — the spatial video format Apple Vision Pro expects. All of this happens automatically. You don't need to understand the codec details.

Choose your quality preset. Higher quality means larger files and longer encode times, but the visual difference is worth it for movies you care about. On an M1 Pro or better, expect roughly real-time encoding — a two-hour movie takes about two hours to convert. Hit convert and let it run. SpaceRay uses Apple's hardware HEVC encoder on Apple Silicon, so your Mac stays responsive while it works.

Step 3: Transfer to Vision Pro

Once the conversion finishes, you have an MV-HEVC file ready for Apple Vision Pro. Transfer it to your headset via AirDrop or USB, and open it to watch in immersive 3D.

The depth effect is genuinely impressive — these movies were mastered for 3D, and they look fantastic on Vision Pro. It's a completely different experience from watching a flat 2D version.

Bonus: Quest 3 Support

Not everyone has a Vision Pro. If you're using a Meta Quest 3 or another VR headset, SpaceRay can also output Side-by-Side (SBS) 3D from the same source file. Same source file, two output formats. Convert once for Vision Pro, once for Quest — or just pick the format you need. It's the same straightforward process either way.
