Motion Clarifications
Align to Motion behavior
When using the Motion Path behavior, the Align to Motion behavior (from the
Simulation subcategory) has no effect. Align to Motion is meant to be combined with
behaviors that animate the position of an object, or with a keyframed motion path. You
can use the Snap Alignment to Motion behavior (from the Basic Motion subcategory)
once a Motion Path behavior is applied to an object.
Blend Mode
The Premultiplied Mix blend mode performs an unpremultiply composite—the
foreground image is assumed to be premultiplied. Artifacts may appear as result of
unpremultiplying pixels whose RGB and alpha values are very small (resulting in pixels
with values of 255). In some cases, the hardware performs bilinear filtering and then
the blend mode unpremultiplies the alpha.
Field Dominance
Motion projects with field dominance set in Project Properties will not be encoded or
rendered with field interlacing unless Field Rendering is enabled in the View menu of
the Canvas. Enabling this setting will also improve playback quality of motion on an
interlaced monitor.
Filters
Pasting a filter does not paste at the current playhead location.
Suggestion : Paste the filter, then press the Shift key while you drag the pasted object.
As you approach the current playhead location, it snaps into place.
Panning
To pan the Canvas at any time, hold the Space bar down, then drag in the Canvas. The
Pan tool is temporarily selected in the Toolbar.
Particles
If you apply certain transformations, such as a scale, rotate, or shear, to an object used
as a particle cell source, the transformation is not respected. For example, if you shear a
rectangle shape, then use that shape as the source for a particle cell, the emitter uses
the original form of the shape (without the shear applied). If an object used as a
particle cell source has an applied behavior, such as Throw or Spin, the transformation
is also not respected. The exceptions to this rule are crop and corner pin, which are
respected when applied to an object that is used as a particle cell source.
Suggestion : If you are using an imported still image, image sequence, or QuickTime
movie as your particle cell source, resize/transform the file prior to importing the file
into Motion.
