For example a ten frame cyclic animation should not use clock 0.0 to 1.0. It should run from 0.0 to 0.9 in 0.1 increments. However if you change to 20 frames it should run from 0.0 to 0.95 in 0.05 increments. The default value for this setting is off. Set odd field flag off Field rendering is sometimes used for animations when the animation is being output for television.
TVs only display alternate scan lines on each vertical refresh.
When each frame is being displayed the fields are interlaced to give the impression of a higher resolution image. If objects in an animation are moving quickly, their position can change noticably from one field to the next. This would save a great deal of time compared to rendering the entire animation at twice the frame rate, and then only using half of each frame. By default, field rendering is not used. By default, the first frame is the even field, followed by the odd field.
