-# 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.
