I have a few video clips and photos at MediaStock. Very nicely designed site offering multiple media products. Worth checking out. It still has a small collection and modest number of contributors. Given their present low profile I'm a bit surprised to have had even a small quantity of both photo and clip sales. It has done better for me than some of the other low earners that have been around longer and have a much higher profile.

Have experienced a few odd rejection notices which I thought strange given that the same work was accepted at many other agencies and sells quite well.  Doubly weird given their small library at this point.

I wish them well and hope they succeed but right now not sure they can build their library fast enough and do the marketing necessary to survive the heavy onslaught of competition....
