Quicktime to Flash Conversion? how can I do this?

You could always send to youtube and then download the result. Follow the download link at the top of the You Tube page to get the video, and rename the downloaded file with a .flv extension.

there are several tools.
Adobe Flash CS3 will do it for you.

If you don't have Flash CS3 or another professional application like Sorenson Squeeze consider a shareware application like VisualHub (just do a Google search for VisualHub and you will find it). VisualHub is shareware and therefore cheap (about $22 USD).

There are most likely freeware apps that will convert the file(s) for you as well. Google is your friend. There is an open-sourced command-line tool as well called ffmpeg (i think); Google that and if you are comfortable at the command line you should be able to install and use that and it would be free.

Best of luck
