Displaying live video

This chapter describes briefly how to display live video in a
resizeable floating window and how to adjust the picture quality.

If you have a Captivator ProTV and are using a TV input, you
will need to refer to Tuning in TV channels on page 39.

Use a display mode with 65 thousand colors or more. The video
is displayed using the colors available in the current display
mode. For example, if you are using 256 colors (8-bit graphics)
the video is displayed using 256 colors.

How to display live video in a window

To display live video you must configure Captivator Pro/TV for
your source and open a video window. If you open the video
window first, it will be blank (or display interference if you are
using a TV input which has not been tuned) until you have
configured Captivator Pro/TV.

1. Make sure that you have connected your TV input or video

source to Captivator Pro/TV.

2. Open a video window by double-clicking on the

Captivator Pro/TV Video Window icon in the VM-Channel
program group.

If you are using a TV input, the window will display
interference and no picture. If you have a video source, the
video window will appear blank.
