Overview; Key Frames And Effects - Sony DVS-7300 System User Manual

Overview

Fitting the optional BKDS-7030 Key Frame Control Panel Unit (also referred
to in the following description as the "key frame control section") in the
control panel allows you to build key frame effects.
This section gives an overview of key frame effects and the associated
operations.

Key Frames and Effects

A key frame is a set of data which determines the instantaneous state of an
image which varies with time.
An effect, in turn, is obtained from a sequence of key frames, interpolated
along the time axis so as to appear continuous.
The following figure illustrates the creation of three key frames with a
circular wipe pattern in three different positions, and the resulting
interpolated effect.
A series of key frames for producing an effect can be held in memory,
identified by a register number. You can then recall the effect, and play it
back.
