Figure 14-46.—Track location on a 3/4-inch U-Matic videotape. Audio  Track Virtually all formats of videotape provide at least two distinct areas for the recording of audio information. They are placed indifferent locations on the videotape but perform the same as regular audiotape. Control  Track The  control  track  consists  of  electronic  blips  or spikes, called sync pulses, recorded in precise intends of  one-thirtieth  of  a  second.  Since  it  provides  the necessary   foundation   for   the   editing   process,   you cannot  edit  without  a  control  track  on  your  blank (source) tape in the insert edit mode.  The insert edit mode is explained later. Laying the control track on a blank videotape is the first step in the videotape editing process in the insert edit mode. Most television studios have a “black burst” generator that produces a crystal black signal you may record and use as a control track. You also can record a control track from another tape — for example, a tape that has color bars and tone. Time  Code  Address  Track The time code address track is used to record cuing information  for  editing.  This  information  may  consist  of audio or visual time/frame identification. Figure 14-46 shows the location of all four tracks on a 3/4-inch U-Matic videotape. VIDEOTAPE  EDITING  PROCESS Videotape  editing  is  essentially  a  transfer  process  in which   a   playback   VCR,   containing   the   recorded segments,  transfers  its  material  onto  an  edit/record  VCR that  assembles  the  various  segments  into  a  finished form. The editing control unit (ECU) is equipped with highly sophisticated electronic circuitry and allows the operator to control exactly where the old material on the edit/record VCR will end and the new material playing in from the playback VCR will begin. The precision of the edits depends largely on your reaction  time  and  skill.  You  must  precue  both videocassette  tapes  accurately  before  the  editing  begins, since you will control exactly where and when the edit will occur while the two VCRs are rolling. You will do your editing in what is called an editing cell. Most NBS detachments have two or more editing cells containing the following equipment: l l l l l l Playback VCR Edit/record VCR Television monitor for the playback VCR Television monitor for the edit/record VCR Audio mixer ECU A typical editing cell is shown in figure 14-47. EDITING MODES On an editing cell, you may make either assemble edits or insert edits. Both are explained in the following text. Assemble Edits In the assemble editing mode, the ECU adds control track and program footage (both audio tracks and the video track) to the edit/record VCR at a predetermined in-edit point. The edit/record VCR continues recording the  new  information  and  the  control  track  until  it  is stopped.   When   you   are   assemble   editing,   you   are inserting a new control track at each in-edit point and 14-36
