r/3DBluray

Hey everyone, I built a free macOS app called Estereopsis to make converting physical 3D Blu-rays into a usable file format painless. Sharing it in case it's useful to others in this hobby.

What it does:

• Extracts the 3D (MVC) title from a Blu-ray 3D ISO/disc via MakeMKV, or takes an .mkv/.m2ts you already have
• Converts it into Full-SBS or Over/Under, Full or Half size per eye, at 720p or 1080p
• Lets you pick exactly which audio tracks to keep
• Subtitles: burn them in, or generate a selectable track that's properly duplicated across both eyes (so it looks correct in 3D instead of split in half) including OCR from the disc's PGS subtitle image tracks
• Quick mode to add/change subtitles on an already-converted 3D file without re-encoding the whole video
• Quality presets that actually scale the bitrate to the real final frame size (not a fixed made-up number), queue support, conversion history, and a quick-test-clip option to check the 3D geometry before committing to a full-length encode

Why I built it: I wanted a simple GUI on top of the usual ffmpeg + MakeMKV command-line dance, with sane defaults and clear feedback (percent progress, plain-language status, not raw ffmpeg frame logs), so I didn't have to remember flags every time I wanted to rip a disc.

Requirements:

• macOS (Apple Silicon)
• MakeMKV installed separately, only if you're extracting from an ISO/disc (can't be bundled due to its license, a one extra one-time setting is needed there so it actually grabs the 3D stream, explained in the included readme)
• Everything else (ffmpeg, MKVToolNix tools) is bundled in the app, no Homebrew required

It's completely free, no ads, nothing locked behind a paywal made for personal use and to share with the 3D movie community. Source credits for the bundled GPL tools (ffmpeg, MKVToolNix) are in the included readme.
