Effects and transitions
Last updated 1/16/2012
Note:
If you apply multiple instances of Paint Bucket to a clip, be sure not to set more than one to use the Fill Only blend
mode. If you set more than one instance to use this blend mode, only the first application of the effect is shown.
Ramp effect
The Ramp effect creates a color gradient. You can create linear or radial ramps and vary the position and colors of the
ramp over time. Use the Start Of Ramp and End Of Ramp properties to specify the start and end positions. Use the
Ramp Scatter control to disperse the ramp colors and eliminate banding. For a video tutorial on using the Ramp effect
and the Calculations effect, see
Coloring A Washed-out Sky With A Gradient In Premiere Pro CS by Jeff Schell on his
Digital Media Net blog.
Note:
Ramps often don’t broadcast well; serious banding occurs because the broadcast chrominance signal doesn’t
contain sufficient resolution to reproduce the ramp smoothly. The Ramp Scatter control dithers the ramp colors,
eliminating the banding apparent to the human eye.
Write-on effect
See an example of the Write-on effect in this video tutorial .
The Write-on effect animates strokes on a clip. For example, you can simulate the action of hand-writing of cursive
text or signatures.
For instruction on how to use the Write-on effect, see the video tutorial Using the Write-On Effect to Create
Handwritten Text in Premiere Pro CS3 and The Write-on Video Effect In Premiere Pro CS3 on the Digital Media Net
website.
Write-on effect: Animating strokes
Brush Position
The position of the brush. Animate this property to create a stroke.
Stroke Length (Secs)
The duration, in seconds, of each brush mark. If this value is 0, the brush mark has unlimited
duration. Use a single, constant, non-zero value to create a snakelike movement of the stroke. Animate this value to
make the stroke expand and contract.
Brush Spacing (Secs)
The time interval, in seconds, between brush marks. Smaller values produce smoother paint
strokes but take more time to render.
Paint Time Properties and Brush Time Properties
Specifies whether paint properties and brush properties are applied
to each brush mark or to the entire stroke. Choose None to apply values at each time to all brush marks in the stroke.
Choose a property name for each brush mark to retain the value for that property at the time that the brush mark was
drawn. For example, if you choose Color, then each brush mark keeps the color specified by the Color value at the time
that the mark was drawn.
Paint Style
How the paint stroke interacts with the original image:
•
On Original Image
Paint stroke appears over original image.
•
On Transparent
Paint stroke appears over transparency; the original image doesn’t appear.
•
Reveal Original Image
The original image is revealed by the paint stroke.
