Here is one more use case I want to touch on and that's automating the video encoding process. We just went over how to encode videos one at time using free tools, but for a lot of web sites you're encoding videos that are uploaded by your users. It would be a pain to encode all of those one at a time. So you want to automate that process. I am not going to go too deep into creating the actual workflow because that's a very big task in itself and requires a lot of programming, but I will give you some of the resources available specifically for automating HTML5 video encoding. First is FFMPEG, which you can find here at ffmpeg.org.
It's an amazing piece of open source software that along with some additional libraries can support all the HTML5 video and audio formats that we need. In fact, a number of other encoding tools are built on half of FFMPEG. There isn't an easy graphic interface for it though. So to use it you have to open a Terminal and work on the command line. If you are not used to doing that, it's probably best left for a developer. Next is Zencoder, which can be found at zencoder.com. Zencoder is a cloud- based video encoding service. Cloud-based means that it's built on one or more of the many computing clouds, like Amazon EC2 or Rackspace Cloud servers which means it can scale what to demand for encoding.
So if you need a few videos or a few hundred videos, it can for the most part do all of them at the same time. Zencoder supports all the HTML5 video and audio formats we need so we can use it to set up an HTML5 media workflow. It's much easier to use an FFMPEG, but it's not free. It will cost you couple of cents per minute a video. So depending on your project and budget, either FFMPEG or Zencoder could be a great choice for automating HTML5 video and audio encoding.
