I've been thinking about adding the walk on agent to my site also, but warn the website visitor first and give them incentive to check out the walk on video by telling them "Click here for special offer"
Let them know that they will see a person walk out on the screen and deliver the special offer message only.
I have learned how to do the green screen effect myself and I have a practice page set up on my site.
I am currently getting opinions from past clients to see if it would annoy them or not. If you want to check out the video it is right here. I am the
Virtual Web Agent. I have a no follow for the whole page, I do not want google to index it.
This is just a practice video and I was reading from an online teleprompter on my laptop so the acting is poor and I did not have the script moving fast enough. The video keying was a rush job and I did not shoot it in HD yet, but plan on it after I have finished doing my survey.
