How
dVeloper Works
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? 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.
