NOTE: The video signal has a time difference of 1/60 second (1/50 second for PAL) between
odd and even fields because it is composed of 60 interlaced fields per second (50 fields
for PAL). When recording video with Very High (D1) resolution, video is made up of frame
units combining two fields – one odd field and one even field. This can cause horizontal
scan lines or flashes in areas with motion because of the time difference between the
two fields. Turning on the de-interlace filter provides clearer video by eliminating these
horizontal scan lines and flashes.
NOTE: The Camera Menu also can be displayed by clicking the right mouse button on the
screen while in the search mode.
