Direction Speciﬁes the direction of the blur. The blur is applied equally around a pixel’s

center; therefore, a setting of 180˚ and a setting of 0˚ look the same.

Blur Length Speciﬁes how much to blur the image.

Drop Shadow

The Drop Shadow effect adds a shadow that appears behind the clip. The shape of the

Drop Shadow is determined by the clip’s alpha channel. Unlike most other effects, Drop

Shadow can create a shadow outside the bounds of the clip (the dimensions of the clip’s

source).

Since Drop Shadow uses the alpha channel, it works well with 32-bit footage ﬁles from

drawing programs and three-dimensional rendering programs that support the alpha

channel.

Note: Because Drop Shadow works best when it is the last effect rendered, apply this effect

after applying all other effects. You can create a more realistic-looking shadow on

animated clips by applying and animating the Motion or Basic 3D effect prior to applying

Drop Shadow instead of animating the Fixed Motion effect because Fixed effects are

rendered after Standard effects.

Echo

The Echo effect combines frames from many different times in a clip. It has a variety of

uses, from a simple visual echo to streaking and smearing effects. This effect is visible only

when there is motion in the clip. By default, any previously applied effects are ignored

when you apply the Echo effect.

Echo

A. Original image B. Image with low echo values C. Image with increased number of echoes

Echo Time Speciﬁes the time, in seconds, between echoes. Negative values create echoes

from previous frames; positive values create echoes from upcoming frames.

Number of Echoes Speciﬁes the number of frames to combine for the Echo effect. For

example, if two echoes are speciﬁed, Echo will make a new image out of [current time],

[current time + Echo Time], and [current time + 2 * Echo Time].

Starting Intensity Speciﬁes the intensity, or brightness, of the starting frame in the echo

sequence. For example, if this is set to 1, the ﬁrst frame is combined at its full intensity. If

this is set to 0.5, the ﬁrst frame is combined at half intensity.

Decay Speciﬁes the ratio of intensities of subsequent echoes. For example, if the decay is

set to 0.5, the ﬁrst echo will be half as bright as the Starting Intensity. The second echo will

then be half that, or 0.25 times the Starting Intensity.
