“Splitting points” for a scene?

[jaybonthius]

I'd like to “split” my scene into multiple video files (for importing into a slides presentation). I understand that each self.play(...) makes a partial_movie_file, but that doesn't solve my problem: it would generate too many files for loop situations, and the filenames are randomly generated. Here's a minimal working example:

class example( Scene ):
    def construct(self):
        c = Circle()
        # video one
        self.play( Create(c) )
        # video two
        for i in range(10):
            self.play(c.animate.set_color(random_color()))

Currently, this renders 11 partial movie files and one complete file example.mp4. I'd like to generate two videos from this scene: one where the circle is created, and one for the entire loop of changing colors, both named in sensible ways (e.g. example_1.mp4 and example_2.mp4. Is there some way to do this programmatically? Some sort of self.split() method?
