# 3D BluRay Processing Script

PowerShell script that converts 3D BluRay files (MVC format) to Side-by-Side (SBS) and Half-Frame Side-by-Side format for 3D TV and VR headset viewing.

## What it does

1. Extracts the H.264 stream from the input file
2. Converts MVC to full-frame Side-by-Side (3840x1080) using FRIM decoder
3. Compresses ProRes full-frame SBS to H.264/AAC for storage efficiency
4. Creates a half-frame SBS (1920x1080) from ProRes SBS for 3D TV viewing

## File Flow

```text
Original 3D BluRay File
    ↓
H.264 Stream Extraction
    ↓
Full-Frame SBS (ProRes, ~200GB)
    ↓                    ↓
Compressed SBS      Half-Frame SBS
(H.264/AAC)         (for 3D TV)
```

## Requirements

- PowerShell 5.1 or later
- MKVToolNix (mkvextract and mkvinfo)
- FRIM decoder (FRIM_x64_version_1.31)
- FFmpeg

## Installation

1. Download [MKVToolNix](https://mkvtoolnix.download/downloads.html) and extract to the script directory
2. Download [FRIM decoder](https://www.videohelp.com/software/FRIM) and place in the script directory
3. Install FFmpeg and add to PATH

## Usage

### Process a single file

```powershell
.\process_3d_bluray.ps1 "C:\Videos\movie.mkv"
```

### Process all videos in a folder

```powershell
.\process_3d_bluray.ps1 "C:\Videos\3D Movies\"
```

## Output Files

For each input file, the script creates:

- `filename-sbs-compressed.mp4` - Compressed full-frame SBS (for VR headsets)
- `filename-half-sbs.mp4` - Half-frame SBS for 3D TV

Intermediate files (H.264 stream and ProRes SBS) are automatically cleaned up.

## Notes

- The script only processes files with MVC streams.
- When using MakeMKV to rip a 3D Blu-ray, make sure to expand each video track and check the unchecked video stream containing 'MVC'.
