Don't know if there's a solution or if it's "just one of those things"...
But I started a project in PPro CS2, with lower third graphics created in AE with an alpha channel so they're self-keying. I had them fade in at the same time a directional blur effect was fading out.
I recently updated to PPro CS4. When I opened this project in CS4, the lower third fades in okay, but at the point the blur reaches 0, the entire graphic jumps down a few lines.
I tried using a different type of blur, but it still jumps.
I tried reinserting the lower third and adding the fade in and blur fresh - but it still happens. To make sure it wasn't just the monitoring, I exported the section and the jump is definitely there.
It works okay without the blur, so I may have to settle for that.
Any suggestions? I just thought - I'll try reimporting the graphic, and also double check the alpha channels settings are correct...
There are a few bugs crawling around some of the filters in CS4 under certain conditions. Try adding an opacity keyframe to the clips set to 100%. it wont affect the effect, but this sometimes makes other filters behave.
Try the directional blur with the direction set to something other than
one of the cardinal headings (0, 90, 180, 270).
