Motion picture film and video simulate motion by displaying a continuous sequence of images or frames.
When you render images as frames, Maya generates one image file for each time frame of an animation. By default, Maya renders images as frames.
When you render images as fields, Maya generates two image files for each time 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”.
For information on the differences between film and video systems see Frames vs. Fields.
To properly view a frame or an animation rendered as fields, you must interlace the two fields together.
Before you render an animation as fields, perform a test render and use the test rendered images through your entire post-production process.
