Edge Green or Radiance 3D mini for Aspect ratio?

Is your display a 2.35:1 (22:9) aspect ratio? If so then they will both have to do exactly the same amount of croping or distorting of the image to stretch it from 16:9 to 'fill' a 2.35:1 screen. It is simply the laws of physics. There is no magic bullet so you either stretch or crop, or perhaps a mixture of the two (but you'll need the Lumagen for that since the Edge is a bit more limited. However, IHMO it's a crummy excuse to buy such a good video processor.

If it's a 16:9 screen and you just want to fill it with 2.35:1 content then pretty much the same applies.

If you don't want to crop the sides then you will need to do some form of non linear stretch. This will affect geompetry but there is no way round that. Lumagen have an NLS mode that does at least allow you to decide how much croping, where the distortion happens and by how much, so at least you can decide the look of this effect.

I think the Mini3D does a great job with the NLS, i have tried several 16:9 sources and stretched them to 2.35:1 and i think it looks surprisingly natural on my cinemascope screen.
Sure, the picure will get a little distorted and you will loose a little information at the top & bottom but like someone said before, you can tweak these settings to your own preferences.

Personally, i love the NLS feature!

Personally I hate the NLS feature, but each to his own. I just don't 'get' the 'must fill the whole screen all the time' mentality. I use side masking for 16:9 cheap pieces of black velvet pinned up to cover the side bars and just watch at 1.85:1.

Still, there would only be one model of everything AV if we all liked the same thing.

I believe the older Vision processors will do this, for a few hundred$ used.

Agreed! I certainly don't stretch everything as I still prefer to watch 2d blu ray in its OAR, but for things like animated 1.78/85 3d and games I am really enjoying the NLS feature more than I expected. I love all the tweaking options as well. VERY cool option/feature to have for CIH users IMO.

It allows you to stretch out, or stretch and crop a 1.78/85 image to 2.35/40. You first setup your projector to fill a scope screen horizontally which will give you a well framed scope image, but 1.78/85 will shoot off the top/bottom of the screen onto your screen wall. In order to get your 1.78 image framed right at this point without having to re-zoom the projector, you setup a shrink option which scales the image down to fit the 1.78 image inside the 2.35 screen (black bars on the sides). At this point you can then NLS the image to fill the 2.35 screen by stretching, or stretching and cropping (you could just crop it as well, but this would not require setting up the NLS feature).

This is not just a feature with the Mini as quite a few VPs can do the NLS from my reading. The Mini does allow lots of options for both the stretching and cropping to tailor things however you think looks best. The downside to all this is you are loosing resolution and altering the original geometry, so it is a trade off and only you can determine if it is worth it. For me it is worth it for some things like 3d 1.78, games, menus and extras (which I never really watch anyway). For 2d blu ray I still much prefer to keep OAR intact AND get the full resolution by zooming my projector down which is extremely easy if you have a motorized lens and even easier if you have lens memory.


Here is a video by forum member BrolicBeast that shows NLS in action........

What is the cheapest video processor that can do 2.35:1 NLS from 1.85:1 image?

I think a lot of you are misunderstanding the o/p's question, and he's misunderstanding what you're telling him. He does not have a 2.35:1 CIH screen. In his first post, he said that he has a Sharp Elite PRO-70X5 TV. That's a standard 16:9 set.

rhed, I think you need to better describe exactly what it is you're trying to do. Your TV is 16:9 (1.78:1). Some movies will be wider than that (2.35:1), which will appear with black letterbox bars on the top and bottom. Some movies or TV content will be narrower than that (4:3, aka 1.33:1), which will appear with pillarbox bars on the sides. Are you trying to make everything fill the screen without bars, or are you only concerned with 4:3 material?

What this ultimately comes down to is that the geometry is what it is. Your TV is one shape. If you want to fit content of other shapes into it, you need to either crop or stretch it. Or you can just learn to deal with the black bars, which is by far the easiest and best solution.
