Once the start screen is filled in and all the videos are imported all you need to do is hit CTRL+Enter to export the finished swf file, ready to share
The template was done on request. Surely someone out there will find it useful (hopefully at least the person that requested it).
The default framerate of the flash is 25 FPS by the way, though it can be changed under properties if you select nothing (click the background). It's always best if it matches the framerate of all of your imported .flv files, though in my tests it didn't matter sometimes and the video played back fine even though the framerates didn't match (the .flv was probably modified upon import by the program). I'll also quickly mention that both mute and videos with audio is supported.
Currently there are no advanced video controls, it just loops forever until the user clicks somewhere - this ends the video and returns the flash to the list of buttons. Possible future updates could include playback controls, it depends on if this thing is actually used enough to merit an update.
Adobe includes a good video to flv converter with Flash CS called "Adobe Media Encoder". Remember to use the FLV format with the On2 VP6 codec and if you want to use very low bitrate for the audio you can increase the sound quality by setting it to mono. Have fun!
