"Up-rezzing" SD to HD for edit?
 

Hello. I read about "up rezzing" standard def footage to HD and "finishing in HD." Can someone please explain this to me? Does the image quality improve significantly?

I'm about to start editing a documentary I shot in SD, part of it 10 years ago on S-VHS (which was transferred to Beta SP a few years ago) and the rest on mini-dv recently. As I will be sending this to PBS for their consideration when finished, in order to increase the chances of a possible sale, would it behoove me to "up rez"? If so is "up rezzing" done to the footage prior to editing or after the edit is done?

I will be continuing yet another documentary this fall, hopefully on HD, money permitting. I have some footage shot last year on mini-dv, and if the rest is shot on HD, would up-rezzing the mini-dv footage to HD improve the quality and perhaps increase the chances of a sale to either PBS or a cable net such as Discovery, History, or National Geographic?

Thank you.

Bob

This isn't my expertise, but as far as I know, the image is the image. If you shot in SD, no amount of uprezzing is going to make it look any better, just as how blowing up a 640x480 image in Photoshop just makes it bigger but pixellated.

The only reason I can think this might be better was for color correction and such, which is destructive and the more pixels you have, the better. However again, the original image still won't look any better so I'm not sure this is still the case.
