The dVeloper AVX plug-in was designed for forensic video analysis.  dVeloper provides the user key image clarification tools such as gamma correction, brightness, contrast, and several monochrome filters. Also, it allows the user to apply a process called "image averaging" to an entire segment of video. By averaging the values of a user definable number of frames together, video graininess and drop outs can be greatly improved.  But what is "image averaging", and how does it work?  Well, unlike most other video effects which operate on a single frame of video at a time, dVeloper combines the information from a user definable number of frames before the current frame and averages the pixel values together to generate an averaged frame. For example, As you begin to average the footage with a Frame Averaging setting of 3, Frame 1 will equal Frame 1. Frame 2 will equal Frames 1 and 2 combined (averaged). Frame 3 will equal Frames 1, 2, and 3 averaged. Frame 4 will equal Frames 2, 3, and 4 combined and so on. See the chart below for a graphical explanation.

Frame Averaging is designed mainly for fairly steady shots. Mounted camera shots are ideal. For example, a suspect looks at the camera for a few seconds and you need to average out those frames to add detail. Applying Frame Averaging to footage with a lot of motion produces ghost images. The general rule is the steadier the footage, the more frames you can select to average.
