5.2.1.2 Features
Features of the Video window include:
• Customizable Window - The user may customize the user interface. Cine-
Plex Editor features a docking window architecture (see “Windows” on
page 6) that enables the user to
— float individual windows to any location
— dock windows to various positions
— close windows as needed
— resize windows by clicking and dragging the splitter bars that divide
them.
• Resizable Video - By default, the Video window stretches or shrinks the
native video resolution (typically 640 X 480) to match the size of the Video
window. The user may also configure it to always show the video at its native
resolution regardless of the size of the Video window by unchecking the
Resize Video to Fit Window item on the right-click menu.
• Coordinate Marker Crosshairs - If coordinate markers are present with
their Show checkboxes selected, the coordinates in effect for the current
video frame appear as crosshairs superimposed over the video image. The
crosshairs appear in the display color set for the coordinate marker. The range
for coordinates is always (0,0) to (1023,767) with (0,0) being in the lower-left
corner, regardless of the video resolution. Before plotting the crosshairs,
CinePlex Editor scales the marker coordinates to the video resolution. Also,
the coordinates that appear in the Video window are always those that are relevant
for the frame in the display—not necessarily the selected marker occurrences.
That is, if different coordinate marker occurrences are selected in the
Marker Occurrences window, in general it does not change the coordinate
crosshairs shown in the Video window. Note that if coordinates have not been
computed or supplied for a frame, the values for the prior frame are used.
• Grid Lines - The user has the option of showing grid lines overlaid on the
video and also determining the spacing and color of the grid lines.
• Tails - While the video plays, it is possible to show the crosshairs with a tail
line that shows the coordinate positions of previous frames. The length and
width of this tail may be configured. By default, the tail changes color according
to the age of the points. The tail color results from a blending of the
marker color with another specified color; the blending amount increases for
older points. If a Fade-to Color similar to the background color of the video
is chosen, a fading effect is created that makes the tail appear to fade away. If
the current time frame is rapidly advanced by using either the find functions
or the Activity window scroll bar, CinePlex Editor can produce a confusing
display for the rendered tails. In this case, from the right-click menu, select
Clear Tails to erase the tail. Also, the user may draw a complete version of
the tail by selecting Show Complete Tail from the right-click menu. The
