Answer 2

SWF (Shockwave Flash) files are not easily convertible to FLV (Flash Video) files as they are usually complex and interactive, and FLV is simply a container for video data. However, depending upon the content and whether it can be presented in a linear fashion, it may be possible to export a sequence (or an entire animation, for instance) from your FLV file as video (such as QT or MP4 format video) which can then be contained by an FLV file.

There are some third-party tools available on the internet, and Adobe's software suites provide the tools necessary for such a task, but it is not likely to be cheap.

Another method may be to use screen-capture software to capture a video sequence from a SWF file. Your mileage may vary.

Regardless of your method, the resulting video file will be many times the size of the original SWF. The reason for this is that a SWF file does not have to encode every single frame of an animation sequence (for instance), but only store certain data objects and resources, and the action scripts to handle them; the 'action' is compiled at run-time by the play-back software (your browser's Flash plugin or a standalone SWF-player, for instance), so a minimal amount of data is required to re-create the final effect. Videos are a linear stream of data that encodes every single frame, and so are exponentially greater in size for equivalent content.
