Video Frame Grabber, Video Frame Averager
Video Freeze Frame     -     448 Series

Now Available for High-Definition!


The Model 448S Video Frame Grabber, Video Freeze Frame or Video Frame Averager creates a freeze frame picture image, upon request, representing the average of a selected number of subsequent frames. This function is most commonly used to reduce dynamic noise, such as "snow", in a scene where there is relatively little or no motion.

In its "live" mode, the input signal will pass to the output. When the Frame Grabber or Averager is flipped to its "average" mode and its "start" button is pressed, it will capture or grab a selected number of subsequent frames or fields of video from the input and provide their average value at its output continually until it is given a command to average a new series of frames. The number of frames is selectable in powers of 2 by a series of four switches on the unit's front panel. In "Frame" Mode, resolution is 720H X 480V pixels at 29.97 frames per second. In "Field" Mode, resolution is 720H x 240V pixels at 59.94 fields per second. Video inputs to the Video Frame Grabber or Averager from analog tape must be time base corrected.
