I take it you are looking to embed video on a website?
Are you looking to turn the video into a flash animation (not sure if this can be done easily, it is the equivalent of turning a movie into an animated gif).
What you probably want to do is put it into a flv. Two ways of doing this:
Use Youtube and embed the video in the html.
Alternatively, use a video conversion app (as above), then drag the flv into Flash (as in the creator application) to create a player, then export it as a swf.
