Particles

Issue: When opening Motion 1.0 projects in Motion 2.0.1, certain particle presets may

appear incorrect.

Workaround: Change the alpha type for the source media used for the particle cell.

To change the alpha type:

1 In the Media tab (of the Project pane), select the particle emitter’s source media.

2 In the Inspector, show the Media tab.

3 Choose Premultiplied Black from the Alpha Type pop-up menu.

Issue: Performance can degrade when adjusting a Motion Path behavior that is applied

to a particle emitter.

Workaround: To improve performance, apply a keyframe path to the particle

emitter instead.

QuickTime

Issue: When a Motion project is opened in QuickTime, the Save or Save As command

causes QuickTime to quit unexpectedly.

Workaround: Use the QuickTime Export command instead.

Replacing footage

Issue: When you replace a clip by dragging another clip on top of it, if the substituted

clip is of shorter duration, Motion still indicates the duration of the longer clip.

Workaround: When replacing footage in this manner, the duration can be corrected in

the Timeline. Drag the right edge of the clip’s bar to the left until it is within the clip’s

actual duration, release the mouse button, then drag the clip back out to the right.

Text

Issue: If the characters in a text object have a mix of styles, and all characters of a

particular style are selected and edited, and if those characters (selected and edited)

are adjacent to other text styles, the adjacent text styles may replace the selected style.

Workaround: Instead of selecting and replacing text, edit the text within the style, then

delete extraneous characters when finished editing.

Issue: A text object already under the influence of a Sequence behavior may not

complete its action if a Simulation, Throw, or Spin behavior that overlaps in time is

applied to the same object. Some sequence behaviors that do not affect the same

parameters as a simulation (such as position) may display improperly.

Workaround: Adjust the behavior so that it does not overlap the Sequence behavior

in time.
