Abstract
A method for reordering an edited digital video sequence composed of digital video fields from multiple sources is disclosed. When the digital video sequence is reordered temporal cadence is provided which will allow for the conversion to a digital film format through a reverse 3:2 pulldown. Let F =(F ,F , . . . ,F ) be the given edited sequence of video fields. In one embodiment, the method calculates an instruction set which is then used to transform F into a new sequence of video fields, denoted F , where most of the fields in F come from F and the remaining fields are “upconverted” fields from F . This reconstitution of F is obtained by optimizing a set of instructions based on various constraints which express the characteristics of the pattern AaBbBcCdDd. By assigning a cost to each violation of the constraints, and to each disruption of the natural flow of time, and to other undesirable properties, a real-valued function is constructed. This real valued function can then be optimized through dynamic programming.
