The most effective video is one that lasts for less than five minutes.

You can create videos limited only by your imagination; anything from “how to” videos to autobiographies. Almost half of all American Internet users have high-speed access, whether it is cable or DSL, so watching videos should not be a problem.

If you need to find a website to store video files, I suggest using YouTube where you can upload your files  for free.

Other Storage Sites
There are many more popular sites where you can save your video. Uploading a video file is extremely easy through these services, and it is even easier transferring video to your blog.
