Applying effects
Last updated 8/12/2010
Texture Placement Specifies how the effect is applied. Tile Texture applies the texture repeatedly over the clip. Center
Texture positions the texture in the middle of the clip. Stretch Texture To Fit stretches the texture to the dimensions
of the selected clip.
Time
Echo
The Echo effect combines a frame with previous frames from the same 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 clip B. Clip with low echo values C. Clip 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 clip out of [current time], [current time + Echo Time], and [current time + 2 x 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.
Echo Operator Specifies the operations to be performed between echoes. Add combines the echoes by adding their
pixel values. If the starting intensity is too high, this mode can quickly overload and produce streaks of white. Set
Starting Intensity to 1.0 per number of echoes and Decay to 1.0 to blend the echoes equally. Maximum combines the
echoes by taking the maximum pixel value from all the echoes. Minimum combines the echoes by taking the minimum
pixel value from all the echoes. Screen emulates combining the echoes by sandwiching them optically. This is similar
to Add, but it will not overload as quickly. Composite In Back uses the echoes’ alpha channels to composite them back
to front. Composite In Front uses the echoes’ alpha channels to composite them front to back. Blend combines the echo
values by averaging their values.
Posterize Time
The Posterize Time effect changes the frame rate of a clip to one you choose. You can use it to slow a 30-fps clip to 24
fps, for example, to give it the look of film, slow it to 18 fps to simulate the jerkiness of old home movies, or slow it even
further to give it a strobe effect.
