Post Production Editing
•	Linear Editing
–	You copy a section of the source tape and edit it to a master tape in the planned sequence.
•	Can be Analog or Digital
•	Source material cannot be accessed randomly
Single source editing
•	One VTR player and one VTR Recorder
•	Joined by an edit controller or edit controller unit.
The Editor
•	Marks and remembers frame locations on the source tape and the record tape.
•	  It sets the preroll(Five Seconds)
•	  Allows you to lay down video or audio or both at the same time.
•	Controls search modes (forward and back)
•	Displays elapsed time and frames
•	Simultaneously starts both machines and keeps them in sync.
 The Editor
•	Previews edits
•	Check edits after they have been made
•	Assemble and Insert Mode
•	Limited to cuts only transitions.
Multiple Source Linear Editing
•	Two Source Machines or More
•	A mechanism for transitions
–	Dissolves, wipes, and other special effects
–	Pulse count system is what we have with most of our machines
•	The other terms is control track.
–	Time Code System or address code system.
Pulse count system or control track system
•	Deals with video frames
•	And where that frame is.
•	30 frames = one second
–	  01-44-23-15
•	Frames accuracy is sometimes difficult.
–	Slippage is possible.
Pulse count system or control track system
•	Rewind tape completely and zero the counter before logging or editing.
–	Speed for which some projects can be edited.
Time code address system
•	Each frame is marked with a different number and a specific address. 
•	More precise than control track
•	Called the SMPTE time code. 
–	SEMPTY time code 
–	Society of motion picture and television engineers/European Broadcasting Union time code.
