Importing 2D Motion Vectors from SmoothKit
If your motion vectors are coming from SmoothKit, then you have to set the
Motion Vectors type to “SmoothKit”.
Once you have imported your motion vectors, refer to Vector Blurs in the
About
Blurs
on page 385 section in order to know how to set motion vectors.
Computing Motion Vectors
The Motio tool uses the assumption of brightness consistency of an image to
generate motion vectors from one frame to the next. That is, the luminance
values remain constant over time, but their 2D position in the image may
change. Flashing lights, shadows, and other image changes that violate
brightness consistency may interfere with the generation of motion vectors
and cause problems with your retiming operation. You may want to first fix
these problems using a Paint tool or CC Basics tool for example, then calculate
the adjusted forward and backward motion vectors with a Motio node. Once
this is done, you can connect the adjusted vectors to a Retimer tool and use
your original image as the input.
If no motion vectors have been imported, you can compute them inside a
composition by adding a Motio node. Certain tool nodes, such as the Retimer,
will detect the absence of motion vector inputs, and will trigger the use of its
internal Motio engine to automatically compute motion vectors. Computing
motion vectors explicitly allow you to use the vectors for more than one vector
consumer tool. For example, you may want to retime some footage with
different speeds and then quickly compare the results. Instead of computing
the vectors twice (in each Retimer), you can use the Motio tool's output twice.
The Motio tool has a non-animated scalar parameter, called Quality, as a well
as a Show Vectors parameter—see
Show Vectors on page 716. This parameter
controls the quality of the motion vectors by applying the motion analysis
only to lower-resolution versions of the input image, up to the resolution
specified by the quality parameter.
