Try cleaning your cache and trashing your prefs. Also update your graphics card driver.
Let me guess: that reflection of the little chart is created using the Vertical Flip effect, right? Yep, seen that bug before: Lines and title flashing across the program monitor and in final export
Apply a Crop effect to the reflection clip, and crop a few pixels off of the bottom of it. The line should disappear. If that doesn't solve it, post back.
It worked. Thank you!!!
By any chance is this one of the specific issues fixed in the recent 5.0.3 update for Premeiere Pro CS5?
I ask because I think I'm having a similar problem. Went home and updated PPro to 5.0.3 and still have the issue.
The screen shot here show the first seconds of an HDV30/60 sequence as the video fades in (bottom layer - lasts about 2 seconds). The top layer is a mask to create the effect of a cinescope camera (no fade). I've cropped the left for demo purposes.
The bottom layer is regular ol' HDV footage. The top layer was created using a Photoshop file with 2 squares using the shape tool and colored black.
For pre-view and render, you can see a light-colored hair line around the top mask. I've applied different effect to remove it, but it won't work. In fact, some effects make it stand out even more. I've also tried using other assets from the PSD (PNG, PPro black video, etc). I also tried the cropping work-around but it did not work.
The screenshot is subtle but it's there. The main thing is that it can be VERY noticable in the BD-R discs I've created played back on set-top players so I'm really hoping there is a fix for it. I did notice that it will appear when I scrub with my finger on the left mouse key. As soon as I let go it appears again.
So PPro is up to date, graphics card is up to date, and I've tried suggested fixes and a few of my own with no luck. Any ideas?
