iDPM/2D DPM Film Look Menus
With Film Look, you can create a flicker or strobe effect (similar to an old film run through a
movie projector). The affect can be adjusted to the desired look by setting the interpolation
(Frame, Field, or Adaptive for Video and Key), turning on Input Freeze and/or Strobe and
adjusting those parameters with the soft knobs. Thresholds can also be adjusted for when
working with cuts and artifacts.
iDPM Kurl Menu
The Kurl effects are grouped into modes, each of which has its own set of menu panes and
related soft knob controls. To access the Kurl menu, select iDPM, Kurl.
The Kurl modes are:
• Position/Size Modulation,
• Page Turn/Roll,
• Ripple,
• Slits, and
• Sphere.
Only one set of Kurl mode parameters can be applied at a time. If you wish to use more than
one mode of Kurl effects simultaneously on the same video (for example, size modulation
of an effect), use multiple iDPMs with re-entry (for information about re-entry, see the
Switcher Concepts Manual).
Kurl Position/Size Modulation Mode
Position and Size Modulation is an effect in which the source video is positioned or size-
modulated through an additive process with either a single wave train, or two wave trains
with the second wave at a right angle to the first. Each of the two wave trains (horizontal,
vertical) may be selected independently from a set of modulation patterns.
Select the Pos/Size Mod Kurl Mode button to access the position and size modulation
controls.
Modulation Pane
In the Modulation pane you select the wave train axis (Horizontal or Vertical) for which the
rest of the menu controls will apply. The following Soft knob controls appear on the right
for the selected axis:
• Amplitude—defines the modulation amplitude (the height of the pattern waves).
• Frequency—defines the modulation frequency and therefore the number of pattern
cycles to appear across the source.
• Phase knobs—The Phase Lock button on the right controls whether the pattern is fixed
(on) or moving (off ). When Phase Lock is on, the Phase soft knob is available to control
the static location of the phase of the pattern. When off, the Speed soft knob is
available to adjust the speed of the pattern’s motion. Negative values can be entered to
reverse the direction of the motion.
