When previewing my content on the timeline, everything looks fine in the preview monitor. When I view the rendered avi file it is totally different.
It seems that there is some kind of a maks or a 'zoom' effect and a mask through the whole movie. That's probably the reason that it takes a long time for Vegas rendering this movie. Strange is that this 'zoomy' effect and the mask is not visible in the preview monitor an I can't remember that I used some kind of this effect in the whole timeline.
Is this a bug or is it possible that I used some invisible effect or mask?
