Well my effort to add some short funny videos has been interesting. A short video (less than 30 second) can be up loaded directly to a tweet. Video take with your phone are very likely to be in the correct format and frame rate. Larger videos than 30 seconds could not be up loaded to twitter. They can be added to your upgraded blog, a tweet will contain a link back to your blog.
I hope this help anyone attempting add videos to twitter.
