OPTICAL SOUND RECORDING
An integral part of the traditional film making process is the creation of the optical sound negative. Mastered sound from a Dolby Certified sound mixing stage is printed onto film stock using a stereo optical recording camera. The sound negative is then combined with the picture negative to create a positive film print. Bell Theatre Services can supply or modify existing mono sound cameras for Stereo Variable Area (S.V.A.) recording. Attachments for Dolby Digital and DTS are also available.
We have supplied and installed over twenty-five 35mm stereo optical recording cameras throughout the world. Bell Theatre Services can also supply 2000ft Camera Film Magazines, Cross Modulation Analysers and Toolmakers Microscopes.
