For the 2008 Artworks program in Cleveland, I had my apprentices record our video mixing session. We mostly used a V4 multi channeled video mixer made by Edirol to mix with, (http://www.planetdj.com/i--V-4) , and we used digitized handmade 16mm films that were created by the group during the program, in addition to an eyeclops toy magnifier camera (http://www.eyeclops.com/).
I also attempted to use the AVMixer Pro software (http://www.neuromixer.com/product-avmixer.php) but didn't realize I had my resolution set too high and my projector could not see the computer. my bad.
all and all my kids really loved mixing. =)
