I plan on using this horizontal expansion lens with my soon to be delivered Sony Pearl projector due to my short 11'2" throw distance. Will High Def 2.35 content be displayed in full resolution? I realize that it has to be removed to display 16x9 content at full resolution.

Thanks,
Tom

I have a Pearl + UH380 + sled - you are going to need a scaler. The Pearl will not do the vertical stretch. I don't know about BR players, but HD-DVD players will not do the stretch either, nor will any HD cable box that I know of.

Oops. I forgot to mention that I will be buying the needed outboard scaler. So will the UH380 plus the needed scaler make the High Def 2.35 image displayed "full resolution"? By the way, any scaler recommendations? I will only use the scaler to do the CIH stretching, nothing else.

Thanks,
Tom

Well, you will not loose any resolution, that is for sure. You will be using the full projector panel for 2.35:1 and all of the pixels of the HD 2.35:1 image (plus some more due to stretching). As to scalers, I have been happy with the Lumagen HDQ, but you could go for a DVDO VP30 or VP50 in that same price range (approx). Also - you will almost certainly be using the VP for all aspect ratios - you will want to, it improves the image on any AR.

Thanks so much for your help.

So 2.35 films will have the same resolution as 16x9 films when using the scaler and lens? Sorry for the dumb question. I realize that playing a 2.35 films on a 16x9 screen setup, one is not getting full resolution. I take it by using a scaler in lens that 2.35 films should look as good as 16x9 films?

Thanks,
Tom

It depends on what "resolution" you are talking about. HD 2.35:1 and 16x9 sources have the same horizontal resolution (1920) but different vertical resolution 1080 for 16x9 vs about 810 for 2.35:1. With an anamorphic lens and scaler, you will use the projectors full panel (1920x1080) instead of 1920x810 for 2.35:1 without the lens and scaler.

One is getting the full source resolution when displaying a 2.35:1 film on a 16x9 screen without a lens and scaler.

This is a matter of debate/opinion. I think 2.35:1 with a good scaler and lens looks the equal of 16:9 - even though 16:9 has more vertical resolution.

One advantage to remember is that all of the anamorphic 35mm release formats have much larger negative image areas on the film than that of spherical 1.85, 1.66, or whatever. Therefore there are inherent/organic native capture benefits of lower film grain, etc. You're manipulating the video image slightly to re-map to the 16:9 panels, but with a top notch scaler, you're doing no damage, and you are reproducing the images faithfully to the original media. With a good lens, projector and 2.35 screen, it is just an incredible experience that you can only compare to the feeling in the big cinema. Definately goose bumpy territory when you experience it at home
