I think the idea is that you make the animation in Blender and then you render to a video format for distribution.
There is burster...
How the Burster works
The Burster plugin resolves two major problems that was keeping the Blender from being accepted in business environments. Firstly, Burster allows you to put your Blender Game Engine file at your website. You do not have to record the (very big) movie, upload into the Youtube to show someone what great thing you have done. Secondly, you do not need to worry that someone will use your work without your knowledge. The blender source files could be now encrypted using very strong cryptographic algorithm. This alows you to sell your interactive 3D content without worrying about protecting the property. What about licensing? The Blender source files aren't covered by GPL v2 license so you can do with them whatever you want. The Burster plugin uses blenderplayer as external process, so Burster is not Blender's derivative - although it is still opensource software on GPL. One part of Burster plugin is closed and licensed with very restrictive license - the decode module - which is a shared library. The Burster plugin is free and open source and its source code is covered by GPL license.
