The footage is a man speaking. With this man speaking I want nothing else to show other than the man speaking. No background. I want it completely transparent, other than the man speaking. A good example is http://www.videotile.co.uk/ . This footage is going to go onto a company’s webpage. I gather that I have to export the file into a FLV format or AVI. I can either go through After effects or directly to Flash professional. I can get the background completely transparent through After Effects but I can only export the footage as either a SWL file or a XFL file. I tried the SWL file and loaded it up in Flash Professional. I have gone to the “Publish settings and changed the window mode to transparent and published that. Once I save the file as a HTML and open it up, the page is blank? Could someone help me out, would appreciate that greatly.
Nobody can tell you anything without proper system info or other technical details. That aside your whole Workflow sounds crooked. One would simply export an intermediate format with transparency like a MOV from AE and then encode it in Media encoder. For the flash specific issues with your embedding and publish settings ask in their forum.

You don't seem to understand how rendering and exporting works in After Effects.
Start here to learn After Effects:
If you go through just the first few items there, you will know about the render queue and Adobe Media Encoder.
