thanks for the advice Walter,
just to update …
well, we’re not exactly ‘Wing and a Prayer Productions’ but it would seem that the Teranex solution isn’t going to happen.
whilst it appears that a Terranex upconvert will give the best conversion, unfortunately the client isn’t going for it.
apparently they have seen an upconcert from the deck and are happy enough with that.
hence my plan is to use the VTR’s upconvert (we’ll be using a Sony HDW series deck)
at this point, for full screen, i’m going to go with upconverting the 720 x 486 SD to 1920 x 1080 HD, then stretching it back up to the correct aspect ratio … basically, do as much of the scaling as posible from the deck.
or, if i can convince them to go with the vertical letterbox look, then will just use the deck’s upconvert to 1600 x 1080 (edge cropped) and not use FCP scaling at all (… but they’re pretty set on full screen so the former is much more likely)
still thanks again for the info
