 # mvhevcsplit
+
  Split a MV-HEVC file into separate left and right ProRes files.
+
+## Purpose
+
+As of January 2024, Apple's MV-HEVC format for stereoscopic video is very new and barely supported by anything. However, there are millions of iPhones (iPhone 15 Pro/Pro Max) that can capture spatial video already. There was no FOSS tool capable of splitting the stereo pair available, especially not in formats suited for post-production.
+
+## Features
+
+There is only one feature: it takes an MV-HEVC file and outputs the left and right eyes as separate files in the current directory. The output format is ProRes 422 HQ, video only. The user is expected to be familiar with tools such as ffmpeg for all other needs.
+
+## Requirements
+
+This has been tested on an M1 Max MacBook Pro running macOS 14.2.1 with [Pro Video Formats 2.3](https://support.apple.com/kb/DL2100?viewlocale=en_US&locale=en_US). Hopefully other configurations work, but your mileage may vary.
+
+## Installation
+
+1. Download `mvhevcsplit` from the releases
+2. Place either on your PATH or in a working directory
+3. In Terminal, navigate to where you placed the binary and mark it as executable: `chmod +x mvhevcsplit`
+4. See "Usage Example" section
+
+In the future I may also try to figure out how to get this added to Homebrew.
+
+## Usage
+
+In Terminal: `mvhevcsplit MOV_0001.MOV`
+
+`output_left.mov` and `output_right.mov`, if they already exist, **will be deleted** and then the new contents will be output to the current directory.
+
+## Contributing
+
+I literally do not know Swift (I'm an Android developer) and had to figure it out for this project, so apologies for the code organization (or lack thereof). There is also no error handling or anything. Consider this to at most a "proof of concept." All optimizations, and improvements are welcome.
+
+## Additional Notes
+
+This would not have been possible without this blog post from [Finn Voorhees](https://github.com/finnvoor): <https://www.finnvoorhees.com/words/reading-and-writing-spatial-video-with-avfoundation> ([archive link](https://web.archive.org/web/20240117091738/https://www.finnvoorhees.com/words/reading-and-writing-spatial-video-with-avfoundation))
