    "abstract": "The concept of frame unsteadiness is explained and established. A device for the voluntary generation of frame unsteadiness of adjustable magnitude has been developed and has been employed for the systematic investigation of picture steadiness. Its action and performance are described. Statistical and psycho-physical evaluations of frame unsteadiness have been effectuated and limit values for its acceptability have been ascertained. Partial causes, such as the effect of motion-picture apparatus (cameras, printers, projectors, etc.), that of the film as such, and the sum of all these effects are described. Methods for the statistical evaluation of frame unsteadiness are given and are illustrated by frequency diagrams, average value curves and tables for the magnitude of frame unsteadiness for various film sizes. Basic points for the reliability of these methods are established. Finally, some conclusions are drawn with respect to the possibility of amelioration of frame unsteadiness in cameras, printers and projectors.",
