Rendering from Unity

Is it possible to render out 25 - 30 frames per second to images?

I know Unity has a CaptureScreenshot method, and that you can render to a render texture and then write out the bytes and encode to an image file. But it is possible to capture 25 - 30 frames per second? Or alternatively, is it possible to render out frames of an animation in the same way an offline renderer would render the frames (i.e. over a time dependant on hardware) in the same way that the Butterfly Effect was achieved?

Cheers. Alex.

just use this one:

And it is a snap… I wish I could modify the script so that it does it at full screen with Alphas…

Should be possible to render color and alpha pass separately and then merge it in photoshop or similar.
Other way is to render color pass, then switch all objects to white, background to black and render it once again, then megre it.
Not so perfect solution, but should do the thing.
