In film and video production, either of the two half-frames that constitute an individual frame. Video fields are used by most video systems to display a frame, first by illuminating odd and then even rows of phosphors on a television screen.
The process of combining fields together is referred to as interlacing, used by the NTSC and PAL video systems
Because video systems display an individual frame in two stages, if you render images as frames (that is, in one stage) and then display them on a video system, the motion of fast-moving objects may appear jerky or choppy.
If your post-production process or final presentation format involve interlaced video systems, you should render images as video fields. (If your animation does not contain fast-moving objects, you could try rendering images as frames.) When you render images as video fields, Maya generates two image files for each frame of an animation, one for each field. (Maya renders a frame at time "x" by rendering one field at time "x" and one field at time "x+0.5".) To properly view these fields, you must interlace them together.
