You can also change the playback speed by dragging the value itself or the slider below it:
left to decrease the speed, right to increase it.
For animations, always begin painting strokes at the layer In point, especially when
adjusting the Playback Speed. Doing this locks the In point (first stroke's start time) to
the In point of the layer, making it easier to locate the beginning of the animation. Then,
simply place the layer's In point where you want the animation to begin in the compo-
sition.
Using the Re-timer (PB only)
The results you get from either using the Re-timer or changing the Playback Speed value
are similar, but there are several important differences:
You apply the Re-timer to individual strokes you select before choosing the Re-timer
•
option. In comparison, changes in Playback Speed applies to all paint strokes on the
layer.
The Re-timer affects only playbacks that use Animate Strokes mode. Playback Speed
•
changes can also influence Hold Strokes and Past Strokes modes.
The Re-timer does not affect the start times of strokes. Changing the Re-timer value
•
shortens or lengthens the amount of time previews and rendered versions take to draw
the stroke. The strokes begin to appear at the same points in time as before, but they
are drawn more quickly or more slowly.
The values for Re-timer are percentages of the original time required to draw the stroke.
•
The default value is 100%. A higher value causes the drawing time to increase, so that a
setting of 200% uses twice the time to draw the selected strokes. A lower value draws
the selected strokes more quickly.
To change playback time with the Re-timer:
Using the Vector Paint Selection tool ( ), click or drag to select the strokes.
1 Right-click (Windows) or Control-click (Mac OS) to open the contextual menu, and
choose Re-timer.
2 In the Set Value dialog box, type a value for Relative Duration (%), and click OK.
Note: You cannot use the Undo command to reverse the Re-timer after you apply it.
However, you can apply the Re-timer again, using the inverse of the value you typed previ-
ously to revert to the original value. For example, if you changed the Re-timer value to
200% and then wanted to go back to the earlier setting, choose Re-timer again and type a
value of 50%.
Painting with Shift-Paint Records (PB only)
Ordinarily, when you create strokes with Vector Paint, those strokes are associated with
the position of the Time Marker when you draw those strokes. After you draw a stroke, you
can draw more strokes at the same time setting or at different time settings. The results
you see when you preview or render the composition depend on your Playback Mode
setting (see "Choosing a Playback mode (PB only)" on page 341).
The Shift-Paint Records options change the way that strokes associate with time settings.
This is called QuickPaint mode. One of the advantages of this feature is that you can create
fast continuous recordings of a sequence of strokes without redraw delays after each one.
To work using QuickPaint mode, you must do two things:
