When uploading a video file (for example to Wikimedia Commons) a thumbnail for the media detail page is automatically generated, apparently somewhere around the middle of the movie. In some cases it would be very welcome if a possibility would exists to change the thumbnail, e.g.:
http://commons.wikimedia.org/wiki/File:Wikilovesart_tropenmuseum_interview.ogv
See a discussion about this subject here in the village pump on Commons:

One suggestion is to add a special keyword to the page to change the thumbnail moment, e.g.:
{{FILEDEFAULTS:thumbtime=50}}
