Setting Motion Detector Sensitivity

The motion detector in DVFilm Maker determines whether pixels should pass through the conversion unchanged (for best vertical resolution) or whether pixels should be sampled from one field only for best film motion.

The sensitivity of the motion detector is set from the Advanced Options pop-up. The default value, 50, works best with most footage, but it may need to be adjusted based on the type and quality of video.

With the detector sensitivity set to zero, you should see video pass through DVFilm Maker completely unchanged. But no film-motion is applied.

With the detector sensitivity set too high, camera noise and compression artifacts will trigger the detector and you will see an overall loss of resolution even when no motion is present.

The way to choose the best value of sensitivity is to select "Show Motion Detector Output" on the Advanced Options pop-up. The motion detector output is white where there is motion detected, and black where there is no motion detected. Select a value for the sensitivity (starting and stopping the process each time) so that static areas of the screen are perfectly black.

Any before-and-after comparisons of your video should be checked on a television monitor, where each field is displayed in succession at full resolution, rather than on the computer screen where either both fields are displayed at once or only one field is shown, and reduction of the image may be taking place.
