What are a few business ideas for shooting video for the web?

I'm not sure what you mean by "business ideas," but there's a good article in a recent issue of Computer Videomaker on how to shoot content specifically for the web...within the last 3 mos.

My number one pet peeve with web video is video that is shot interlaced and then not properly deinterlaced prior to encoding.

If you have a camera that has a "frame movie mode" or a progressive mode, use that for shooting footage for which the ultimate destination will be the web.

I don't know if this qualifies as a business idea.
