Using the De-Interlace Filter to Eliminate Horizontal Scan Lines and
Flashes
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.
