Basic Node Setup
The Time Speed node setup is as simple as connecting a 2D image into the orange
background input of the node.

Inspector
Speed
This control is used to adjust the Speed, in percentage values, of the outgoing image
sequence. Negative values reverse the image sequence. 200% Speed is represented by a
value of 2.0, 100% by 1.0, 50% by 0.5, and 10% by 0.1.
The Speed control cannot be animated.
Delay
Use this control to Delay the outgoing image sequence by the specified number of frames.
Negative numbers offset time back, and positive numbers advance time.
Interpolate Mode
This menu determines the how the time speed is processed in order to improve its visual
playback quality, especially in the case of clips that are slowed down. There are three choices
in the menu.
 Nearest: The most processor efficient and least sophisticated method of processing;
frames are either dropped for fast motion or duplicated for slow motion.
 Blend: Also processor efficient, but can produce smoother results; adjacent duplicated
frames are dissolved together to smooth out slow or fast motion effects.
 Flow: The most processor intensive but highest quality method of speed effect
processing. Using vector channels pre-generated from an Optical Flow node,
new frames are generated to create slow or fast motion effects. The result can be
exceptionally smooth when motion in a clip is linear. However, two moving elements
crossing in different directions or unpredictable camera movement can cause
unwanted artifacts.
