Working with PlasmaWipe Effects

PlasmaWipe effects are real-time plug-in effects that use gradient image bitmaps to create wipes and segment effects. There are 64 preset effects, and you can create your own by creating new gradient images.

While one of the wipe effects plays, the system maintains a value called a threshold point and changes the value gradually from black to white. All gray tones in the gradient image that are lighter than the threshold point are replaced by outgoing video. All gray tones in the image that are darker than the threshold point are replaced by incoming video. As the threshold point gets closer to white, more of the incoming video appears. The result is a smooth, custom wipe.

The following illustration shows the black and white gradient image used by the Horiz Twirl PlasmaWipe effect and the resulting effect, with softness applied. This effect gives the impression of a curling spiral that reveals the image underneath.

Using PlasmaWipe Effects

PlasmaWipe effects are two stream, real-time effects that you can use as either transition effects or segment effects. As transition effects, PlasmaWipe effects allow you to create custom wipes. As segment effects, you can use PlasmaWipe effects as static wipes. For example, you could design a PlasmaWipe effect that gives the impression of fog on the top and bottom of the video image or a custom border for an effect similar to a picture-in-picture effect.

Testing the Animation

You can use the following procedure to preview the animation that the system performs on your graphic. This example uses the Horiz Twirl image from the PlasmaWipes folder.

To test an animation:

  1. Select Image > Adjustments > Brightness/Contrast.

The Brightness/Contrast dialog box appears. The following illustration shows the image and the Brightness/Contrast dialog box.

 

2. Move the Contrast slider all the way to the right to view the animation with hard edges.

 

3. To view the animation with some softness applied, move the Contrast slider to the left to select a lower Contrast number.

 

4. Move the Brightness slider from left (-100) to right (+100) to view the animation. The following images show three stages of the animation.

 

To adjust the image in increments of 10, click the Brightness slider and use Shift+Up Arrow or Shift+Down Arrow.

Using PlasmaWipe Frame and Border Effects

PlasmaWipe frame and border effects allow you to add a variety of edge treatments to a clip. The following illustrations show several examples.

Frame and border effects are in the PlasmaWipe Avid Borders category of the Effect Palette. There are two groups of these effects:

  1. Border effects allow you to darken the edges and corners of an image

or give a tint or shadow to the sky as though the image was shot through a lens filter. For example, the image with no effect in the previous illustration shows a slight darkening of the corners created during the original filming of the clip. The bottom right image uses Soft Window to accentuate this effect. Border effects include the following:

  • Round Border
  • Soft Sky
  • Soft Window
  • Square Border
  1. Frame effects allow for textured, colored frames. These effects have the word Frame in their name. There are three versions of each:
  • Large: places a frame around the entire image. These effects areintended for use with DVE effects such as picture-in-picture (PIP) effects.
  • Medium and Small: remain centered in the image and cannot be resized or repositioned.

 

To Apply a frame or border effect to an existing DVE such as a PIP

effect:

  1. Apply the PIP effect to a clip in the Timeline.
  2. Double-click the effect’s icon in the Timeline. The system steps into the effect and displays the nested tracks.
  3. Drag the frame or border effect onto the upper track in the nested effect. For example, the following illustration shows the Stone Frame

Large effect applied to the 1.2 track.
