Why no Superbit for 480i content on blu-ray? - Blu-ray Forum

We all know that 480 content is a fact of life at times. Usually comes in the form of extras. Being played on blu-ray it still has stunning color and playback, but the fact remains. It is DVD content on blu-ray.

Here is the thing with 480 transfers. Most of us know that DVD tops out at 10 Mbit playback rate. If your original content can not be greater than 480 lines, then why not encode it at Superbit levels? It's a blu-ray player for crying out loud. It can handle it.

Unless space is that much of an issue, I'd rather see 480 content play back at 15 or 20 mbit, rather than less than 10. The experience would be that much richer.

Because it would mean a re-encode from the DVD release extras. In other words, $$ with no ROI.

as brandon said, multiple encodes are not good for the studios. i'm sure as more and more new releases come out we'll see extras that are in hi-def. on older catalog titles though, they'll just throw in what they already have canned
