zencodable

https://github.com/sbeam/zencodable

provides a `has_video_encodings` class method to your models that allows you to configure and set up any Zencoder settings you will need to create multiple output video container formats (mp4, ogg, wmv, etc) from a single uploaded source file. Uses the Zencoder API (zencoder.com) and (as of now) expects you to have an S3 bucket where we can ask zencoder to place the generated files.
