Apple Motion 4 - Manual (Page 1059)

HUD Controls
The HUD contains the following controls: Delay, Number, Decay, and Amount.
Scrub
Moves a virtual playhead around a clip, allowing you to change the timing of the clip
without moving it in the Timeline. Additionally, this filter allows you to animate the offset
parameter, often with interesting results. Try adding the Scrub filter to a clip, then applying
the Randomize behavior to the Frame offset, with the “Offset from” parameter set to
Current Frame. Also, you can create a hold frame by setting Offset to First Frame, then
using “Frame offset” to find the frame you wish.
Important: Scrub does not affect clip audio.
This filter causes rasterization in 3D groups.
Parameters in the Inspector
Frame offset: Sets the offset of the virtual playhead.
Offset from: Sets the position from which the virtual playhead is offset. Values available
include First Frame or Current Frame.
Frame Blending: Turns the blending between frames on and off.
Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls
The HUD contains the following controls: Frame offset, Offset from, and Frame Blending.
Strobe
Strobes the image by holding frames for a set duration. The effect is that moving images
appear to skip frames as they play.
Parameters in the Inspector
Strobe Rate: Sets the number of frames of each strobe.
Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls
The HUD contains the following control: Strobe Rate.
Trails
Draws light or dark trails following an object’s movement. This filter is only effective with
moving images.
