Chapter 7 Managing clip media
• Media outside the clip marks is erased except that portion referenced by a
subclip, playlist event, or program.
• All subclips and events generated from the source clip retain 1 second of media
before the mark-in and after the mark-out.
• Event-in becomes the first video frame of the file
• Event-out becomes the last video frame of the file
• Clip length becomes the total file length.
Understanding field dominance
In interlaced video, each frame is composed of two fields. In Grass Valley systems
such as K2, 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 system
goes to field 1. When you navigate through a clip to the end, K2 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.
