Editing is Selective Copying

1
Editing is Selective Copying

• Select what will be copied.
• Pick and Arrange sequences and shots together.

2
Technologic

• Knowledge of system settings.

3
Basic Equipment needed for editing

• 2 Decks- player and recorder.
• Monitor- ideal 1 for each deck.
• Edit Controller

4
Recorder

• Must be capable of insert editing ( this allows
  editor to get exact point where the frame
  starts.)
• Must be able to attach to an edit controller.

5
Player

• Must be able to attach to an edit controller.

6
Edit Controller

• Is the Brain of your decks and edit session.
• Controls machines that you are using.
• Enables editor to make accurate decisions.
• A simple edit controller will only control two
  decks. ( player Recorder)
• An advanced controller will have control of
  switchers, multiple decks, special effect
  devices, Audiotape machines, and remember all of
  your edits. ( Grass Valley System)

7
Edit Controller

• Edit controllers guide the mechanical functions
  of tape machine.( play, stop, rewind, etc.) to
  find and remember the exact edit points that have
  been selected. ( In or Out points )
• Two ways of finding these edit points are
• By reading control track pulses
• By reading time code information

8
Control Track Edit Controllers.

• Perform edits by count the frame pulses that are
  recorded on control track signal. When an edit
  point is selected, the controller will
• Back space from that edit point( referenced by
  the pulses.)
• Start the machines and perform edits at the
  specified point.

9
Control Track Edit Controllers Disadvantages.

• Control track editors, because they are counting
  only pulses, have no reference to go back to if
  they miss a pulse. For this reason they are
  generally considered to be accurate to within
  only one or two frames.

10
Computerized Time Code Edit Controllers

• Read time code information

11
Time Code

• Additional recorded information that can be
  recorded onto tape signal. This information
  provides each frame a specific address.
• Time code edit controllers use this address as
  reference.

12
Advantages of Time Code Edit Controllers.

• Frame Accurate
• Faster
• Control several machines, Digital video effects
  units, perform transitions, and previews.

13
System Connections

• The Edit System is connected with each of the
  cables carrying the signals running directly from
  one machine to the other.

14
System Connections

• For a simple copying system, each recorder
  machine will have the following connectors.
• Video IN and OUT
• Audio Ch 1 IN And OUT
• Audio Ch 2 IN and OUT
• The Player machine only needs OUT Connectors.
• The cables should run from the Audio and Video
  OUT connectors on the Player to the Audio and
  Video IN connectors of the Recorder.

15
Dub Cable

• Transfers video information in a component form.
  (What is component?)
• Recorder can receive a Line signal and Dub
  signal ( this can be selected in the front panel
  of deck)
• Dub signal provides better quality video signal.
• Dub signal does not go through video processing
  equipment.

16
Component Video- Separates the Signal into three

• Y
• PB
• PR

17
Y Luminance Signal

• Y 30 red 59 green 11 blue
• C Chrominance Signal- PB-PR
• C I Q Matrix
• Saturation Amplitude of the I and Q signals
• Hue Phase developed by the difference in
  amplitude between the I and Q signals

18
Dub Cable

• Transfers video information in a component form.
  (What is component?)
• Recorder can receive a Line signal and Dub
  signal ( this can be selected in the front panel
  of deck)
• Dub signal provides better quality video signal.
• Dub signal does not go through video processing
  equipment.

19
System connections? Setting up Monitor.

• To monitor editing, cables need to be run from
  recorder deck ( Video OUT) to monitor Video IN.
• If using several monitors for each deck, then
  cables will need to be run from each deck to
  respective monitors.
• Certain monitors have several inputs. You can
  use one monitor to check different sources.

20
Loop Through

• When a signal is looped through a source.
• Example Send signal out of playback deck into
  Monitor, and out of monitor to recorder deck.

21
Termination

• When looping signal through, the last source
  needs to be terminated.
• Can be done in two ways
• Using a Terminator-An external connector that can
  be attached to the last Out.
• Built in Switch that connects to a 75 ohm
  resistor. When switch is activated the signal
  will be terminated.
• Monitors that have a single input connector will
  be automatically terminated with a built in 75
  ohm resistor.
