Vision Operator’s Manual (v12.0 MD) Squeeze & Tease Sequences and Wipes • Ops 15–5
•Use the Tension knob on the S&T MD Sequence Menu 2-2 to affect how tight or
loose the curve is. Lower tension gives a looser, more sweeping curve while
tightening the tension brings the curve closer to a straight line.
•Use the Bias knob on the S&T MD Sequence Menu 2-2 to balance how much
influence the previous and next keyframes have on the spline through the current
keyframe. Increased bias places more importance on the smoothness between the
previous and current points, while a decreased bias places more importance on the
smoothness between the current and next points.
•Use the Continuity knob on the S&T MD Sequence Menu 2-2 to affect how
smoothly the path passes through the keyframes. The standard spline path moves
smoothly through each keyframe but by adjusting the continuity, you can make the
path effectively come to a point at a keyframe and then abruptly move away
towards the next keyframe.
11. Press Insert Keyframe to insert Keyframe 1 into the sequence.
12. Add additional keyframes as required. Proceed to Step (13.) to insert the final keyframe
and complete the sequence.
Operating Tip — If you want to adjust a keyframe that has already been created. You can
select the keyframe, modify it as required, and then press Overwrite Keyframe on the S&T MD
Sequence Menu 1-2. The selected keyframe will be overwritten with the current channel
selections.
13. Position the channel for the last keyframe.
14. Select a wipe modifier as follows:
• Press More B Wipe Modifier on the S&T MD Sequence Menu 2-2.
Wipe Modifier — S&T MD Sequence Menu 2-2
•Use the Wipe knob on the S&T MD Sequence Menu 2-2 to select how you want
the wipe to transition off-air. You can choose between the following:
› Knife Edge — This wipe modifier finishes with the channel 90 degrees to the
screen (edge on to the screen).
› Slide Off — This wipe modifier moves the channel directly off-screen in the
direction that the channel was last moving. This is done by moving the
channel in the X and/or Y axis.
› Spin Off — This wipe modifier rotates the image off the screen based on the
rotation that is applied to the channel between the last two keyframes. The
speed and direction of rotation between the two keyframes determines the
speed and direction for the channel moving off screen.
