Apple Motion 3 - Manual (Page 960)

960 Chapter 10 Using Filters
Parameters in the Inspector
Delay: Sets the amount of delay between echoes. Values range from 0 to 1. A value of
0 is a zero frame echo, and a value of 1 represents a 60 frame echo.
Number: Sets the number of echoes.
Decay: Sets the amount of time it takes for an echo to decay.
Amount: Sets the relative opacity of each echo. Values range from 0 to 1.
Mix: Sets the amount of the filtered frame to be mixed with the original source frame.
Values range from 0 to 100%.
HUD Controls
The HUD contains the Delay, Number, Decay, and Amount controls.
Scrub
Moves a virtual playhead around a clip, allowing you to change the timing of the clip
without moving it in the Timeline. Additionally, it 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. Values range from –100 to 100.
Offset from: Sets the position from which the virtual playhead is offset. Values can be
selected from First Frame or Current Frame.
Frame Blending: Toggles the blending between frames on and off.
Mix: Sets the amount of the filtered frame to be mixed with the original source frame.
Values range from 0 to 100%.
HUD Controls
The HUD contains the same controls as the Inspector, with the exception of the Mix
control.
Strobe
Strobes the image by holding frames for a set duration. The effect is that moving
images appear to skip frames as they play.
