I shot some footage in 24pa and 24p, some with the widescreen mask and some without...Don't ask! I edited and rendered it in premiere 6.0 and threw in a bluescreen mask to even all the shots with no problem. Now...I capture the same footage in Vegas for the 24p thing and in the end I add the mask and bing...Vegas alows image to be vivible outside ( top and bottom) of the masked area...Why?
