Hey there,
I just came across your youtube video and your AR businesscards. I got a question on that one, since I as a student work on an AR project. How did you guys get the transparent background in your inserted video? I tried to do it using after effects and chroma keying, but this just left me with a black background.
I would appreciate it if ya could help me with this. Looking forward to hearing from you.
Best regards,
Ray

Hi Ray,
Hi There,
Be sure to encode the video as .flv preserving the alpha channel. Also, here’s a good link with info.
