2 questions about a flv file

programming flash
1

I have 2 questions:

  1. I have a flv movie embeded into a fla file. Is there a way I can export the flv ?

  2. How can I edit the flv file after I exported it ? Can I convert it to swf and decompile the swf and use flash to edit it ? Or do I need a special flv editor ?

Thank you.
