# 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'.
