Apart from presentations and documents, you can upload and share videos on SlideShare. From Oct 11, 2011 in order to upload videos, you need to have a SlideShare PRO account. Previously you could do this from a free account, but that has been discontinued. 

SlideShare has built SlideShare videos in response to user feedback. We are not trying to become a video site. We simply want to give our users some value added services using video as a format.  

To upload a video, follow the steps below:

• Click on the Upload button on top of the home page
• Login to your account
• Click on the Upload publicly or Upload privately button (you need a SlideShare Pro account to upload privately)
• Select the video you want to upload
• Add a Title (mandatory), Tags, Category and Description

It is not possible to replace a video file once it is uploaded.
