track can be any composite signal (i.e., black burst, color bars, or color
background, etc.) recorded from the beginning to the end (or at least longer
than the program to be edited). Refer to Figure 1-8.
b. A good way to check if the outer edge of the tape is damaged is to
use a video tape evaluator. The video tape evaluator will identify damaged
portions of the tape by displaying a readout of any track that is unusable.
11. Preroll. In order for a VTR to record or play back a control track, all
moving parts (drum, tape, etc.) must come up to speed and lock up. During
editing, preroll backs both tapes approximately five seconds from the tapes'
Without this preroll time, the VTRs will not achieve a
stable lock up of the control track at the beginning. This, in turn, will
produce an unstable picture when played back or edited.
It is for this
reason you should always record at least five seconds or more of control
track before playing back or editing.
12. Continuity. Do you remember watching some of the early movies where the
actors seemed to jump from one part of the screen to another without
Some of those jumps were caused by a lack of pictorial
continuity. As a camera operator/editor your primary goal is to present the
story in such a manner that each scene conveys part of the main idea to the
viewer. All related scenes should flow one into another so there will be no
gap in continuity.
All unrelated scenes must be joined together into the
story with smooth transitions.
Therefore, continuity is defined as the
smooth flow of actions from one scene to another.
