Alpha Problems
On my timeline I have 2 video tracks. Track 1 is my main content and Track 2 (above track 1) I have placed a video that has an alpha.
All looks good and renders out fine.
I then added a “levels effect” to Track 1 and instantly my alpha looks like a bag of hammers. If you mute the effect the alpha goes back to normal.
Any Idea of what I am running up against here?
Any input would be appreciated.

Mercury enabled Levels control or regular old software one?

CS5.5 on Windows 7 64bit so I am thinking mercury.

Is it possible to test it with the non mercury version?
I’m merely guessing…

Not sure. How woudl I go about that?

If you look in the effects panel…you can sift the listings to show you accelerated or non accelerated versions of fx. I may be wrong about that….As I’m not in front of it, I can’t verify…

Are you running a CUDA approved card (I.e., Nvidia 4000)?

I have attempted exporting AE file in a number of different file types without any difference. I have also attempted exporting PP sequence in a number of different files types without success.

to clarify…
Originally I thought the Levels Effect was causing the problem so I removed the levels effect and rendered the timeline to find the same problem with the banding.

How about something other than Matrox code? Quicktime Animation + Alpha?

Yup, Tried Animation with Alpha and a slew of others with the same result which leads me to believe it is a premiere issue.
