68 Advanced PlaylistingEditing a ClipAlthough not a part of Advanced Playlisting, the Image Server provides accurate tools fortrimming the head and tail of a clip. Trimming and playlisting together allow the Image Server tocreate accurate and complex rundowns. Trims do need to be performed before inserting a clip intothe playlist. (Edits to clips in an existing playlist will take effect the next time the list is loaded.)The edit controls are activated with the Edit check box on each channel’s GUI window.This region contains a number of buttons that define the beginning and end of a selected region,plus their associated time code displays.Non-destructive Mark In and Mark Out trim points can be set to define a portion of the clipto be played. These “pointers” do not create a new clip from the original material; they act likevirtual trims, and material outside of the trim points is excluded, but can be retrieved by resettingthe Mark points. After setting the Mark In and Mark Out points, clips will play between thesepoints. These values are saved with the clip.Edits may be saved to the current clip by de-selecting the Edit check box, or choosing Savefrom the clip window File menu. Save As works to save the edit points to a new clip name, even ifthe edits have not been saved in the current clip. This is a great help while conducting an Edit-while-Recording.Mark In ButtonSets the current time code value into the Mark-In point time display.

When a field is highlighted, enter a numeric value from the keyboard.• Whether a clip is still or playing, press Mark In to capture a time code value from theclip’s current position.Mark Out ButtonSets the current time code value into the Mark Out point time display. The Mark Out buttoncan capture a time code value from the clip when it is still, or on-the-fly.Mark Out DisplayDisplays the time code for the Mark Out point.
