+# burnSubs
+You found my burnSubs tool. The goal for this tool is to ease the
+conversion of arbitrary video files with soft-subtitles in the SSA/ASS
+Substation Alpha format into simple stereo hard-subtitled video files.
+
+## Features
+* softsub to hardsub conversion
+* embedded font files
+* selecting specific audio streams
+* selecting specific video streams
+* automatic selection of language preferences
+* default surround sound to stereo down-mixing
+  * opt out CLI flag available
+* anti-clobbering default behavior
+* auto-cleanup on error
+
+## Prerequisite Tools
+Firstly, the tool will yell at you if the tools it needs don't exist.
+Feel free to just run the tool, and it will let you know what you're
+missing.
+
+* [`ffmpeg`](https://ffmpeg.org/) - the one and only
+  * `ffprobe` - usually comes with ffmpeg
+* [`jq`](https://stedolan.github.io/jq/) - file/pipe based JSON processor
+
+
+## How does it work?
+`burnSubs` takes an input video file and tries to figure out what
+audio streams and subtitle streams exist within the file. It stores
+metadata in `/tmp` while it runs. When running it will pull the
+streams within the input file, and try to select Japanese language
+audio streams, and a non-signs subtitle stream (i.e. a full language
+subtitle stream) to add to the output video.
+
+Before transcoding it will then extract the subtitle file to pass into
+`ffmpeg`'s subtitle burn in filter, and will try to down-mix any
+surround sound input streams to stereo. Downmixing, track selection,
+clobbering behavior, and verbosity can all be controlled to a limited
+extent by CLI flags.
+
+## Can you make it do *XYZ*.
+Give me an enhancement request in github and I'll take a look.
