Hi Tiger:
I would think the first rule is to keep it simple. Video gets too much into quality of photography and editing whereas a simple digital photo with a reasonable resolution camera, >7Mp, would to just as good a job.
If you're photographing it for posterity or local consumption, video would be OK, but the minute you put it on the internet, you have to consider download times, speeds and line quality which would dictate that you reduce the size as much as possible. Where I live, I have high speed but the next village (26 km away) have only dialup over poor quality voice lines. I've even used dual dialups to try to get the speed up, often with little effect.
