Transforming a page curl
Printer-friendly version (135 KB)
This tutorial guides you through the steps of creating keyframes to transform a page curl effect that is included with the Matrox realtime plug-in.
Set up the Adobe Premiere Pro Timeline
Complete the tutorial Applying a page curl to a title, so that your Adobe Premiere Pro Timeline has a graphics clip (title) on track Video 2, and a video clip on track Video 1. The graphics clip should have a Bottom RC Roll page curl applied to it.
Edit your Matrox effect
To edit your page curl, do the following:
- Select the clip on track Video 2, then click the Setup button beside your effect in the Effect Controls window.
- Click the Transform tab to display the transform controls.
You can adjust the transform settings using the controls in each of the Position, Offset, Size, and Rotation areas, or you can work directly in the Preview Window using your mouse. Clicking and dragging in the Preview Window will resize, rotate, or position your clip depending on which transform settings you've selected.
The black vertical bar on the Transform track is the Positioner. It indicates the current frame of the effect. Drag the Positioner to the middle of the Transform track, if it is not already there.
Create a new keyframe
With the Positioner in the middle of the effect, type the following values for X, Y, and Z in the Position text boxes: X: 125; Y: 70; and Z: -300. Notice that as soon as you do this, a yellow keyframe symbol appears on the Transform track. This symbol indicates that an action will take place at that frame, namely, the position of the clip will be at the values you just specified.
Next, without moving the Positioner, type the following values for X, Y, and Z in the Rotation text boxes: X: -90; Y: -35; and Z: 0.
Create two more keyframes
Drag the Positioner to the beginning of the Transform track. In the Transform menu below the Preview Window, choose Default. This creates a new keyframe with default transform settings.
Finally, drag the Positioner to the end of the Transform track and make sure that the X, Y, and Z Position values are set to 0. Type the following values for X, Y, and Z in the Rotation text boxes: X: -360; Y: 0; and Z: 0. Alternatively, you could set the X value for the Spin control to -1, indicating a full rotation.
The Transform track should now contain three keyframes to complete your effect. An interpolation is automatically set between the keyframes to create a gradual transition from one keyframe's settings to the next.
Click OK to return to your Timeline.
