US Patent 7843489 Maintaining continuous film mode with bad edits

A method for editing spliced-together video comprising a cut-out sequence followed by a cut-in sequence, both being in 3:2 pull-down format. A bad edit is detected, and either a number of contiguous frames at the end of the cut-out sequence and/or a number of contiguous frames at the beginning of the cut-in sequence are deleted in order that the 3:2 pull-down sequence is preserved in the spliced-together video. Alternatively, a first number of frames at the end of the cut-out sequence and/or a second number of frames at the beginning of the cut-in sequence are copied/renamed and inserted from other fields in order that the pull-down format is preserved in the spliced-together video.
