coverting DV to HD and back again
My job is to do the compositing and simple object removal on this project. Right now I have some footage of live action in DV 720×480. It’s in a letter box (the black bars on top and bottom)
The footage is ultimately going to be in HD resolution 1920×1080 squared pixels.
The producer wants me to take the DV footage and up res it to HD, do the VFX so it can be outputed to HD. But at the mean time for a temporary/rough versions, He wants me to convert it back down to 720×480.
Right now I’m just scaling the footage in After Effects so in the HD size comp, the footage would cover the screen w/o any black letter box.
scale percentage is “x = 297%, y= 291%”
and to bring it back down the scale percentage is “x=33.67%, y=34.36%”[but my scale measure ments were base on just using my eye to figure it out and it’s not really ‘exact’ just guessing]
Is there a way to scale and rescale exactly? besides just guessing
If you have any solutions or someway to point me to the right direction that would be great.

thanks guys, for the input. I was also reffered to that link in the previous response as a solution. Now I would just have to convice my producer to spend a little more money on it. Hah what’s that chance of that happening. It’s good to hear that there are people who understand my situation. In the mean time I’m just going to continue w/ the scale solution that Dave mention.
