Digital Video Editor

       This article describes the user interface for a software
function that allows a user to easily edit digital video.  Since this
idea is based on word processing editors with which many computers
are already familiar, the Digital Video Editor is easy to learn and
use.

      The Digital Video Editor controls are shown at the bottom of
the window in Fig. 1.  The controls include a slider box, a
horizontal sliding area, left and right directional arrows, and a
readout display showing which frame of the video appears in the
editor window.

      The user moves the slider box to change the digital video frame
that is shown in the editor window above the controls.  The slider
box is sized to reflect the proportion of the entire digital video
that the frame represents.  If the frame is one of 100 frames, then
the slider box is small, about the size shown in Fig. 1.  If the
frame is one of three frames, then the slider box is large, about
one-third the size of the sliding area.

      The user can change the video frame shown in the editor window
by moving the slider box like a slider switch.  The user grabs the
slider by selecting it.  If the user has a touch-sensitive computer
screen, then the user touches the slider box.  Otherwise, the user
can position the computer cursor on the slider box and press the
keyboard or mouse Enter key.  To move the selected slider box with
the keyboard, the user presses the left and right keyboard arrow
keys.  To move the selected slider box with the mouse, the user moves
the mouse to the left and right.

      The user can also move the slider and video frame by selecting
a location on the sliding area.  When the user selects a location on
the sliding area, then the slider box moves to that location and the
video frame that is at that relative position in the video appears in
the editor window.

      The user can also move the slider box by selecting the left and
right directional arrows at the end of the horizontal sliding area.
When selected, the directional arrows move the digital video one
frame.  For example, when the user selects the right directional
arrow, then the digital video moves to the right one frame.

      The Digital Video Editor includes a readout display to show the
user on which frame the digital video is positioned.  The readout
display is formatted as follows: Frame X of Y, where X is the current
frame, or frame portion, and Y is the total number of frames.  The
user can move the digital video to a specific frame or frame portion
(e.g., frame 17.5) by selecting the readout display (the text cursor
appears in the X position), typing in the requested frame, and
pressing the keyboard Enter key.  The digital video direction and
speed controls are described in (*).

      The Digital Video Editor actions are shown in the open "Edit"
pull-down menu in Fig. 1.  To mark a video frame or frames, the user
performs the followi...
