In the beginning We did Video but as you know it has changed dramatically in the last 10 years.
Here's what I would do.
Play the original Virtual Santa, and pick out a new scenes that you would like to be in your 30 second snippet and splice them together using "Tech Smith's" Camtasia Studio - https://www.techsmith.com - You can download it for FREE for (30) days.
Then, I would take that file and using your VHS recorder, Record take the scene using your VHS camcorder and your good to go.
Here's the only problem ... You need an old VHS recorder.
I know its not much of a response but I needed to do the same thing so I asked my mother-in-law if I could use here and it came out just fine.
I have in the meantime figured it out thanks. I downloaded a video off youtube where a great looking Santa is talking and then rides off on his sleigh after waving, looks great with the audio that I already have of him talking, so all good now thanks!!
