NOTE

The video signal has a time difference of 1/50 second (1/60 second for NTSC) between odd and even

fields because it is composed of 50 interlaced fields per second (60 fields for NTSC). When recording

video with Very High (D1) resolution, video is made up of frame units combining two fields – one odd

field and one event 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.

Slow Play… Plays video at low speed (x1/2, x1/3, x1/4, x1/6 and x1/8)
