Based on a post in the Adobe Forum, requesting a soft Fade-out for a Crawl Title, I decided to do this little tutorial, using the fixed Effect>Motion>Position for the Title (to create the Crawl) and then the Linear Wipe Transition Effect (Note: not really a Transition in the purest sense. It is found in the Video Effects Panel) to create the Fade-out.
This was done in PrPro 2.0, but should be applicable to PrE, as well.
In my case, I placed my Video onto Video Track 1, and my Title above it. I adjusted my first Keyframe (first Frame of the Title) for Motion>Position to a horizontal position off-screen to the left. I then set a Keyframe at the end of the Clip to a horizontal position off-screen to the right. I left these Keyframes set to a Linear setting, as I did not need any Ease-In, or Ease-out, and wanted the “travel” of the Title to be purely Linear - zero Velocity change.
Next, I added the Linear Wipe Transition Effect to the Title. I keyframed it come in about 2/3 of the way through the Duration of the Title. I adjusted the Angle of the Linear Wipe to 270ÌŠ and the Feather from 92.5, and Keyframed up to 150, near the end of the Title.
As the Linear Wipe Transition Effect is not found in PrE, at least up to version 4, I am doing a separate tutorial for PrE, as things must be done differently.
Here is the screen-cap of PrPro's Effects Control Panel, showing the Keyframing for the Title's Effects:
