SkyDrive Help & How-to
You can view H.264 (.mp4) and Windows Media Video (.wmv files) videos directly from SkyDrive in most web browsers. Other video formats can be uploaded to SkyDrive, but they might not play directly in a browser and might need to be downloaded to a computer. To play videos on SkyDrive in a web browser you might need to have Silverlight installed.
The videos you add to SkyDrive must be smaller than 100 MB.
