Time Filters

Other filters manipulate objects in two or three dimensions, but this group filters manipulates objects in the fourth dimension—time. Time filters are most often used with moving footage.

Echo

Echoes an object’s motion by repeating frames. As a result, moving areas of an image leave a streaking trail behind.

This filter causes rasterization in 3D groups. For more information on rasterization, see About Rasterization.

Parameters in the Inspector

Delay: Sets the amount of delay between echoes. Values range from 0.1 to 1. A value of 0.1 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.
Mix: Sets the percentage of the original image to be blended with the filtered image.

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 apply 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 want.

Important: Scrub does not affect clip audio.

This filter causes rasterization in 3D groups. For more information on rasterization, see About Rasterization.

Parameters in the Inspector

Frame offset: Sets the offset of the virtual playhead.
Offset from: Sets the position where the virtual playhead is offset. Values include First Frame or Current Frame.
Frame Blending: Turns the blending between frames on and off.
Mix: Sets the percentage of the original image to be 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. As a result, moving images appear to skip frames as they play.

This filter causes rasterization in 3D groups. For more information on rasterization, see About Rasterization.

Parameters in the Inspector

Strobe Rate: Controls the number of frames played back per second.
Mix: Sets the percentage of the original image to be 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.

This filter causes rasterization in 3D groups. For more information on rasterization, see About Rasterization.

Parameters in the Inspector

Duration: Sets the duration of trails.
Echoes: Sets the number of echoes trailing behind.
Decay: Sets whether trails decay over time or disappear at the end of the duration.
Trail On: Sets the value type that triggers trails. This pop-up menu can be set to Light or Dark.
Mix: Sets the percentage of the original image to be blended with the filtered image.

HUD Controls

The HUD contains the following controls: Duration, Echoes, Decay, and Trail On.

WideTime

Holds frames before and after the current frame to stretch the image’s motion out in time.

This filter causes rasterization in 3D groups. For more information on rasterization, see About Rasterization.

Parameters in the Inspector

Duration: Sets the number of frames before and after the current frame that are blended.
Decay: Sets the amount of time the added frames are held.
Amount: Sets the amount of opacity of the delayed object being overlaid. Values range from 0 (no reduction) to 1.0 (transparent).
Mix: Sets the percentage of the original image to be blended with the filtered image.

HUD Controls

The HUD contains the following controls: Duration, Decay, and Amount.
