What you NEED to Know Before Touching a Video File

Hanging out in subtitling and video re-editing communities, I see my fair share of novice video editors and video encoders, and see plenty of them make the classic beginner mistakes when it comes to working with videos. A man can only read "Use Handbrake to convert your mkv to an mp4 :)" so many times before losing it, so I am writing this article to channel the resulting psychic damage into something productive.

If you are new to working with videos (or, let's face it, even if you aren't), please read through this guide to avoid making mistakes that can cost you lots of computing power, storage space, or video quality.

routes – an array of route objects
- request - configuration of a request.
  - method – a string according to RFC 2616.
  - pattern - a string to match, can be an escaped regex string. If regex is specified, it must match the entire request path.
- response - configuration of the response.
  - resourcePath - relative path of the resource to serve, if the request was matched.
  - contentType - optional an override for the resource content type. By default it's automatically deduced from the file MIME type.
