pan and scan location

andy

I have some footage from a digital TV broadcast. It was all broadcast as 16:9 but is mostly 4:3 pillarboxed into the 16:9 frame. During the broadcast, the DAR flags were changing to switch from letterboxed (for the real 16:9 material) and pan-and-scan for the 4:3 material.

I'd like to copy all of this to DVD as pan-and-scan from beginning to end. But for some of the real 16:9 material I could do with shifting the pan and scan frame slightly to one side (so that it is not exactly central).

Is it possible to do this or has pan-and-scan simply become centre-cropping only? And is there any software which can do this?

Edit: I just found this statement in a DVD faq: a portion of the image is shown at full height on a 4:3 screen by following a quot;center of interestquot; offset encoded in the video stream according to the preferences of those who transferred the film to video.

I guess I'm asking if there's any software which will allow me to change the quot;center of interestquot; offset, possible by modifying the value in the VOB files?
