Yea, here is the problem as I understand it: When you apply an OFX filter such as any of the BCC filters, the filter asks Vegas Pro what the dimensions of the video are. If you are using the default layout with your preview setting is set to Preview Auto, Vegas will tell BCC that the video is 480x270 even though it's really 1920x1080 because the preview window is resized to 480x270 by default. You must set your preview to Full (preferably Best/Full) BEFORE you apply any OFX filter so that the filter gets the true project dimensions to work with. Then you can set it back to Preview (Auto) and everything will continue to work.
