Fotolia has put out a call for video submissions. The company said the move is a response to overwhelming demand. The microstock agency seeks content ranging from animation to stop-motion, digital and traditional video. To make it through Fotolia’s approval process, submissions need to be 32 by 240 to 1920 by 1080, 24 to 30 frames per second and 5 to 60 seconds in length. Fotolia plans to license a variety of digital formats, including high definition.
