Since most new movies on HD-DVD or BluRay are in 2.35 ratio but being output at 16:9, what is the true resolution inside the real film area? is it 1920x1080p still or 1920x817p before the vertical stretch? Thanks.

Since Hi Def DVDs are being coded square pixel non-anamorphically, it is the latter. Were it the former, there would be no need for electronic stretch.

so I guess this 2.35 excise is not going to get you any more resolution out of the 1920x1080 panel.

Not if you view it as simply a gain in source resolution. It does allow you to utilize your full panel which achieves greater brightness and finer granularity in the image since you gain 33% more pixels, hence less image structure.

It could also be argued that with a good scaler that has few scaling artifacts there are gains to be made with image quality as well, since the additional pixels are interpolated from the existing.

This discussion from the AVS archives covers this very issue.

So if picture detail is not improved using say a Sony Pearl 1080p projector with a Lumagen HDQ scaler and a UH380 lens over the detail one gets from the smaller 2.35 image on a 16x9 screen what is the advantage of using this option versus just zooming out as far as detail is concerned? I know brightness is 33% higher. Would the other advantage of lens/scaler just be pixel visibility on 2.35 films?

Thanks,
Tom

The situation is exactly the same as with DVD, all the same benefits and pitfalls apply to HD DVD/Blu-ray that apply to DVD (CIH wise).

The only difference is HD DVD/Blu-ray are much better sources to begin with so the results are likewise much better.

See what an anamorphoscopic lens can do, see movies the way they were meant to be seen
