In my experience in order to make a good HD video from a flash, you export the flash as individual images, jpeg or png i dont remember exactly wich one and you can set the zise so that they can be 1080p, those images then are imported into sony vegas pro and it will convert it to a video that you can upload to youtube or other sites. For the audio is the same you export your audio from flash and then import it to vegas, then with the video and audio combined in vegas you export the video and done.
