Flickr is now offering video uploading to users of its free service. Last year, Flickr Pro members got to start sharing 90-second video clips; now, free members can upload two videos per month, in addition to the 100MB monthly photo-upload limit already in place. Pro members get an upgraded feature: They can upload HD videos, though all users will be able to view the HD videos. Flickr announced the expansion on its Yodel Anecdotal blog. The site also rolled out Flickr Clock, a sort of global user-gen timeline to showcase uploaded videos according to the approximate time they were shot.
