In “Red vs. Blue,” one of the short films at this weekend’s third annual Machinima Film Festival, two gun-totting, faceless patrolmen from the video game “Halo” act more like Samuel Beckett characters than intergalactic warriors. Perhaps the most popular incarnation of machinima, “Red vs. Blue” is now up to 66 episodes with more than a million total viewers. Motion-capture animation, the standard 35mm technique, is an expensive, painstaking process with each movement scripted frame by frame. But in machinima, amateur filmmakers control video-game characters like puppets, record their movements in real time and voice over the dialogue. AP reports.
