Abstract

A post production offline editing system for storing unedited video takes in a random access memory (which is preferably a set of laser video disk players), displaying selected takes (or individual frames from selected takes), and generating an edit list which defines an edited video program. The system includes a computer programmed with software providing an integrated software environment which enables a user conveniently to log unedited takes into the system, and to generate an edit list suitable for use in a subsequent online editing operation. The system software provides global access to a variety of video post production environments at any point during an offline editing operation. The system software presents menus to the user including icons or mnemonic text in windows which may be conveniently selected by the user using a mouse. In a preferred embodiment, the invention includes a video special effects unit capable of processing the stored takes to simulate various video transitions between scenes (such as dissolves, fades, and wipes), to enable the user to view a show defined by an edit list which specifies such transitions. The user interface includes a convenient means for jogging (and shuttling) the laser disk players using a mouse.

Claims12

Dependent claims

An offline editing system, including:

random access storage means, including a first video disk player and a second video disk player, for storing unedited video takes, wherein each of the takes comprises a number of frames;
display means connected to the storage means for displaying selected frames of the stored takes;
a programmed computer, including user interface means for providing a user with global access to a number of video post production environments at any time offline editing operation of the offline editing system, and edit list generation means for generating an edit list in response to user-entered commands, wherein the user interface means includes means for controlling the storage means in response to the commands and means for controlling operation of the edit list generation means in response to the commands;
a mouse connected to the computer for asserting the commands to the computer;
and
a computer monitor connected to the computer and having a screen, wherein the user interface means includes a disk player jog/shuttle means including
means for displaying a first jog/shuttle window on the screen and a second jog/shuttle window on the screen;
means for controlling the first video disk player in response to a first selection command and subsequent control commands from the mouse;
and
means for controlling the second video disk player in response to a second selection command and subsequent control commands from the mouse, wherein the first selection command selects the first jog/shuttle window and the second selection command selects the second jog/shuttle window.
