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. If a portion of the shot is already digitized, as indicated by the edit-to-it file, then the predigitized material is used with a new digitized section being created for the portion of the shot from the source not already digitized.

Claims

1. A method of editing comprising the steps of:

initiating an edit-to-it file when material from a linear source is required as a source for an edit;

identifying an initial point for a shot on the linear source;

prerolling the linear source until the initial point for the shot is reached;

laying the shot into the edit;

simultaneously recording the material from the linear source into a storage unit starting from a handle prior to the initial point until an end point of the material defining the end of the shot is reached when the edit-to-it file indicates that the shot has not been previously digitized; and

updating the edit-to-it file to indicate the portion of the linear source that is recorded in the storage unit.
