ending a control track at each out-edit point.Your video
may be unstable (picture tearing or breakup) at the edit
points during playback Therefore, you should allow for
extra video after your intended stop/out-edit point
otherwise, you will not be able to edit onto the last part
of the video. Assemble edits are very convenient
because you simply add segments to build the video
story or program.
Insert editing allows you to add or change video or
audio separately or together without affecting the
control track. As you insert the new material over the
existing information, you use the control track already
established on the edit/record videocassette to lock the
signal into synchronization.
The main drawback of insert editing is that you must
lay along enough control track on the tape before you
start editing. A one-hour program tape requires you to
lay one hour of black or color bars and tone before you
start the editing process.
NOTE: After laying the control track in the
assemble mode, be sure to switch to the insert mode on
the ECU. If you remain in the assemble mode when you
make your first video or audio edit, the end of the edit
will look like a green flicker on the television monitor.
This is caused by a break in the control track There is
no way to correct this break without relaying the control
track for the entire length of the tape. The best approach
for you to take is to stay in either the assemble or insert
The two basic editing techniques in videotape
editing are continuity cutting and compilation cutting.
Both are explained in the following text.
