Cut/Lap: A New Method for Programmable Fades and Soft Edit Transitions Using a Single Source VTR
Facilities are described for obtaining fades to and from black, with no time-base correction. Previous methods required two video sources through a switcher. The cut/lap unit offers the editor an alternative to straight cuts. A slow cut/lap is like a slow dissolve and thus offers new production values. The unit can be operated in a range of functions, for 30-frame and 60-frame sequences. The operator can devote his entire attention to scene content and effects. A normal fade-out, fade-in is similar to a cut/lap. The crossover takes place at one-third video level. Control is with a Motorola 6802 microprocessor. The circuit must pass sync and blanking at unity level, and the audio can be bypassed. The cost is moderate and the unit can be utilized in a wide variety of program production applications. A demonstration tape was shown when the paper was presented in order to permit comparison between normal fades and cut/lap effects.
