Estimating the term…
The operator projects motion-picture film using a projector. A counter counts frame pulses during both forwards and reverse film transport, and thereby keeps track at all times of the film frame count. The operator during forwards projection when he sees the start or end of a scene pressss a storage switch which causes the scene-start or scene-end frame count to be stored. The operator also preselects the type of recording-transition effect to be implemented. The operator then commands dubbing of the scene, whereupon a minicomputer begins to automatically implement a series of operations, including projector motor control and recording control, to implement the selected recording-transition effect, in a programmed manner dependent upon the stored frame counts and the instantaneous frame count. In the middle of the dubbing of a scene, the operator can change the transition effect he selects, to produce a transition effect at the scene end different from that selected for the scene start.
A method of automatically producing fade-in, fade-out or fadeover recording effects at predetermined recording transition locations on a film comprised of a series of film frames using a reproduction machine capable of transporting the film both forwards and backwards and reproducing the images on the film frames, counting means capable of counting frames during both forward and reverse film transport, and programmable control means capable of storing frame counts, the method comprising causing the counting means to feed into the control means information in the form of frame counts identifying the predetermined recording-transition locations on the film;
An apparatus for automatically producing fade-in, fade-out or fadeover recording effects at predetermined recording-transition locations on a film comprised of a series of film frames, comprising, a reproduction machine including a transport motor capable of transporting the film both forwards and backwards and reproducing the images on the film frames and including recording means operative for receiving and recording information onto the film, control means comprising a minicomputer operative for counting frames during both forward and reverse film transport and for storing frame counts identifying the predetermined recording-transition locations on the film, and command means comprising operator-activated operation switches activatable by the user for causing the control means to store frame counts identifying transition locations, and for causing the control means to control the recording means and automatically implement preselected recording-transition effects at the recording-transition locations, and for causing the control means to control the transport motor to effect forward and reverse transport of the film during recording and implementation of recording-transition effects.
