A/A Roll Edits

OLL DITS
Two types of roll edits are commonly used in video editing — A/A rolls, and A/B rolls.
You can do both types of rolls with MXPro. A/A rolls can be accomplished with relative
ease. As you'll learn later in this section, you can also do A/B roll editing with MXPro,
although it does require good preparation and manual control of the devices. If you
intend to do a lot of A/B roll editing, we recommend you consider a dedicated device,
such as a Videonics A/B Roll Editor.
Simple cuts between scenes do not require special features. All you have to do is pause
the recording VCR at the end of one scene, then release pause when the next scene
begins.
A/A roll edits can be defined as Single-Source editing because all of the original materi-
als come from a single videotape. MXPro offers special features designed specifically
for these types of situations.
An easy way to add interest to a single-source transition is to use the A/A roll edit
(sometimes called an A/X/A edit). In this situation, the video freezes at the end of one
scene, then a dissolve or other effect transitions to the next scene.
You are producing a murder mystery. The door opens and the villain sneaks into the room.
Slowly he moves toward the camera, then you press FREEZE to freeze the killer's menacing
glare!
Next, you pause the recorder and set up MXPro to perform a dissolve. Then you find the next
scene and start it playing a bit before the scene starts. There's the victim — it's granny, sitting
in a rocking chair with her back to the camera. You start the recorder. It's still recording the
frozen picture. At the correct moment you transition from the frozen closeup of the murderer to
granny in her chair. As the killer's face dissolves away, granny turns and we discover it's the
constable, ready to arrest the scoundrel!
Procedure
To perform a roll edit such as this:
1
Roll the tape and press FREEZE at the appropriate moment to freeze the end of
the scene.
2 Pause the recording device.
3 Set up the transition you want.
4 Position the source tape just before the next scene and let the scene play.
5
Release pause on the recording device to record more of the frozen picture.
6
At the appropriate moment, run the transition between the frozen picture and
the rolling video from the next scene.
This type of A/A roll works best when the recording device has flying-erase heads — a
feature that lets the VCR make a clean break when you pause the recording.
