Export Video out of Unity

Is there a way to export video of gameplay. The concept I was thinking of is creating some architectural visualization within unity3d and export the animation of the visualization out to video, or even exporting out video and audio for use such as a short film or a cartoon series.



You can always use fraps: http://www.fraps.com/

You can use one of various available .NET video API's - or you can do a series of screenshots using Unity's `Texture2D`
