Time effects
Echo effect
The Echo effect combines frames from different times in a clip. The Echo effect has a variety of uses, from a simple visual echo to streaking and
smearing effects. The results of this effect are visible only if the clip contains motion. By default, any previously applied effects are ignored when
you apply the Echo effect.

Echo Time (seconds) The time, in seconds, between echoes. Negative values create echoes from previous frames; positive values create
echoes from upcoming frames.
Number of Echoes The number of echoes. For example, if the value is 2, the result is a combination of three frames: the current time, the current
time + Echo Time, and the current time + (2 x Echo Time).
Starting Intensity The opacity of the first image in the echo sequence.
Decay The ratio of the opacity of an echo to the opacity of the echo preceding it in the echo sequence. For example, if Decay is 0.5, then the
opacity of the first echo is half of the Starting Intensity; the second echo is half that, or one quarter of the Starting Intensity.
Echo Operator The blending operation used to combine the 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.
Maximum Combines the echoes by taking the maximum pixel values from all of the echoes.
Minimum Combines the echoes by taking the minimum pixel values from all of the echoes.
Screen Emulates combining the echoes by sandwiching them optically. This setting is similar to Add, but it won’t 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 Averages the echoes.
Posterize Time effect
The Posterize Time effect locks a clip to a specific frame rate. Posterize Time is useful on its own as a special effect, but it also has more subtle
uses. For example, 60-field video footage can be locked to 24 fps (and then field rendered at 60 fields per second) to give a filmlike look. This
effect is sometimes called Strobe in hardware devices.
Animating the value of the Frame Rate slider can give unpredictable results. For this reason, the only interpolation method allowed for the frame
rate is Hold.
