Understanding field dominance

In interlaced video, each frame is composed of two fields. In Grass Valley systems such as a K2 Summit/Solo system, video is field-1 dominant; each frame consists of field 1 followed by field 2. For example, when you navigate through the clip to the beginning, the K2 Summit/Solo system system goes to field 1. When you navigate through a clip to the end, the K2 Summit/Solo system goes to field 2.



The in point of any trimmed clip always starts at field 1 of a frame. The out point of a trimmed clip is always one frame past the stop point of the clip. For example, if the last playable frame is 01:15:00,04 then the out-point mark is 01:15:00;05.
