For some institutions, the biggest roadblock to posting video to Web sites is the worry that the videos can be taken by other people, Mr. Moskowitz said. Because information posted on Wikipedia is free and unlicensed, someone can use a posted video for a profit-making venture.
Mr. Moskowitz said the best strategy for protecting your videos is to keep the HD version of a video for your own use and post the standard-definition version to Wikipedia. Institutions could brand videos as well, although other users could crop out the institutional seal or post a new video in its place.
