One question that is often asked deals with the length of a posted video. Usually the shorter the better. It is very rare for users to consume an entire 45 – 60 minute video in one sitting. It is even a challenge for most videos over 10 minutes long. It is best to keep it under 10 Minutes - a good goal is to aim for 4 minutes. If you have longer content that must be posted, break it down into parts making it easier for the user to consume.
MOV, MPEG, AVI formats can get very confusing. The most popular way to make video available on the internet is through a streaming server. This allows users to view part of the video as the rest downloads to their temporary memory. Each streaming server utilizes a different format. For example, the UC Denver Downtown campus has a Flash Media Server - their preferred format is Flash Video (.flv).
There are many services like YouTube or Viddler that can do all the difficult work for you. Simply upload one of several accepted formats and they will encode and host the file for you on their streaming server. They will then provide you the necessary embed codes and or links to make the content available on your website. Their systems are all configured to optimally deliver video to the Internet. This includes aspect ratio, window size and file size.
Permission / Copyright
This is a very important thing to think about when posting video to the Internet. If you are not the Author/Creator of the original content you may not be entitled to publically post it. Anytime you have a staff member bring a dvd or tape that needs to be converted and hosted, you should ask for them to obtain written permission from the publisher or copyright holder.
