VirtualMV/Flash12 (CS6)/Journal/Alpha Channels

The On2 VP6 codec supports Alpha channels, or the ability to have a transparent area on your movie

According to Reinhardt and Dowd (2007, p.572)^[1] to create video with an Alpha Channel generally requires 4 steps

Acquire video footage
Import video into a video effect application. Example, Adobe after effects
Render the footage with the alpha channel (in After Effects: Video Outupt > Channels > RGB + Alpha)
Encode with On2 VP6 codec. Use FLV Video Encoder supplied with Flash. Make sure you check Encode alpha channel check box.

Anderson(2007)^[2] demonstrates this effect, and shows how far Flash can go by including it in a transparent popup window.
