  • Patent number: 5781435
    Abstract: An edit-to-it function of an editing system allows an editor to combine linear editing with non-linear editing. A linear source, such as a magnetic tape, may be identified as an edit source, as well as already predigitized material. When the linear source is selected as an edit source, an edit-to-it file is created that indicates the status of the source--which portions are already digitized and which are not. The editor identifies an in-point on the edit and an in-point on the source. The source prerolls, as applicable, to the in-point and lays the shot into the edit while simultaneously recording the shot including a handle prior to the in-point into a digital storage device. When the editor identifies the end of the shot, either by a predetermined out-point or on-the-fly, the source stops and the recording terminates.
