FLV - Flash Video File is used with the Flash Video Exporter plugin only. This is really the only type of file that it is compatible with. If you can find another program that includes Adobe Flash and includes some type of FLV file support, you should be able to make use of this format as well. This type of file also contains a short header and different video and audio packets. It is definitely well worth your wait. There are also certain non-Adobe and Macromedia programs that are supported through FLV. You can even transfer data through Quicktime Pro and other programs.
