Haver you installed the latest driver for you graphics card?
And Premiere latest update?
Welcome to the forum.
Where did this footage come from? If Ann's suggestion does not take care of things (and it should), you might want to tell us much more about the Source Footage.
I will try to do that. Thank you!
Well, the raw footage is an avi filmed with a handycam. This error occurred
the next day after I finished the editing in Adobe Premiere cs5. It might
be something wrong with the title graphics that I use, but still if there's
a solution I would like to find it out as this error occurred before.
Maybe you should show us or tell us more about the title graphic if that is what induces this effect.
I'm not quite sure which software was used for creating those title
graphics, but as you can see in the print screen there are different
Make sure the graphic is RGB and not CYMK.
