Sample Spread
This slider is displayed only when Interpolation is set to Blend. The slider controls the strength
of the interpolated frames on the current frame. A value of 0.5 blends 50% of the frame before
and 50% of the frame ahead and 0% of the current frame.
Depth Ordering
This menu is displayed only when Interpolation is set to Flow. The Depth Ordering is used to
determine which parts of the image should be rendered on top. This is best explained
by example.
In a locked-off camera shot where a car is moving through the frame, the background does not
move, so it produces small, or slow, vectors. The car produces larger, or faster, vectors.
The Depth Ordering, in this case, is Fastest on Top, since the car draws over the background.
In a shot where the camera pans to follow the car, the background has faster vectors, and the
car has slower vectors, so the Depth ordering method would be Slowest on Top.
Clamp Edges
This checkbox is displayed only when Interpolation is set to Flow. Under certain circumstances,
this option can remove the transparent gaps that may appear on the edges of interpolated
frames. Clamp Edges can cause a stretching artifact near the edges of the frame that is
especially visible with objects moving through it or when the camera is moving.
Because of these artifacts, it is a good idea to use clamp edges only to correct small gaps
around the edges of an interpolated frame.
Edge Softness
This slider is only displayed when Interpolation is set to Flow and Clamp Edges is enabled. It
helps to reduce the stretchy artifacts that might be introduced by Clamp Edges.
If you have more than one of the Source Frame and Warp Direction checkboxes turned on, this
can lead to doubling up of the stretching effect near the edges. In this case, you’ll want to keep
the softness rather small at around 0.01. If you have only one checkbox enabled, you can use a
larger softness at around 0.03.
Source Frame and Warp Direction
These checkboxes are displayed only when Interpolation is set to Flow. These controls
determine which frames and which vectors are used to create the in-between frames. Each
method ticked on will be blended into the result.
Prev Forward: Takes the previous frame and uses the Forward vector to interpolate the
new frame.
Next Forward: Takes the next frame in the sequence and uses the Forward vector to
interpolate the new frame.
Prev Backward: Takes the previous frame and uses the Back Forward vector to
interpolate the new frame.
Next Backward: Takes the next frame in the sequence and uses the Back vector to
interpolate the new frame.
Common Controls
Settings Tab
The Settings tab in the Inspector is also duplicated in other miscellaneous nodes. These
common controls are described in detail at the end of this chapter in “The Common
Controls” section.
