SEQUENCING
Sequencing is the function of performing live transitions between pre-stored key frames. You
may program and initiate key frame sequences based on the 10 available key frame registers (00
through 09).
Some common uses of sequencing include: transitioning from a full screen image to a
compressed image for an “over-the-shoulder” shot; or from a full screen to a compressed image
to reveal a scroll on-screen (stock tickers, school closings, news tickers, weather alerts); or from
compressed image to compressed image for on-screen special effects. The uses of sequencing
are limited only by your imagination. Sequences can include borders with transitioning colors,
aspect ratio changes, position changes, size changes; they can also be reversed, paused, looped or
continued.
