MovieREP: A New Movie Reproduction Framework for Film Soundtrack

Film sound reproduction is the process of converting the image-form film soundtrack to wave-form movie sound. In this paper, a novel optical imaging based reproduction framework is proposed with the basic idea that restoring film audio damage in the image domain. In traditional reproduction method, the scanning light emitted by film projector causes inversible physical damage to the flammable film soundtrack (made of Nitrate compounds). By using optical imaging method in film soundtrack capturing, our framework can avoid the damage and the self-ignition problem. Experiment results show that our framework can improve the reproduction speed to 2 times while maintaining equal sound quality. Also, the sound sampling rate can be enhanced to 162.08%.
