- Abstract
- Conversion from the rate of 60 television fields per second to 24 film frames per second in television recording is generally accomplished by omitting from the record every fifth consecutive half-field. Consequently, there is a picture splice across the center of every other film frame. In a camera having a properly adjusted mechanical shutter, all points of the picture receive the correct total exposure. However, the exposure intensity and time relationships differ for points inside and outside the splice, and this can lead to a density difference across the splice. This form of shutter-bar has been eliminated in the new experimental recording film described.
