Of course, but then again, in Oklahoma (for a lot of people, especially in the capitol since it is a more conservative state) Christianity pretty much is the endorsed religion there, despite the idea of separation of church and state. I also personally believe that, except for a select few, separation of church and state is a very hard thing to do. When you grow up with a certain set of values, that tends to affect your viewpoint on certain things, including political things, which can cause quite a few problems when trying to decide the laws and such. (Abortion anyone?)

Also, there was a group moving for removal of the Ten Commandments monument, and I believe there was a court case over it, although I can't think of the group at this time.

Also, Oklahoma is NOT the South.

Correct. Oklahoma is where the wind comes sweepin' down the plain.

Or is it that past films were never shot in 4K resolution so its impossible to have that just like how its impossible to have HD of TV shows shot on tape ?

A lot of current blu ray releases of old films were scanned in and restored at 2K, 4K, and even 8K anyway, they could easily just pull up those masters.

I didn't realise you can put out a movie in a higher resolution than it was shot on. I thought 1080 was the maximum resolution you can get out of film and that is why HD was possible on older movies. How much resolution can you get out of film?

[MrPopo]

Film is analog, so your ability to get resolution comes down to the current state-of-the-art in scanning technology. Think of it like using a higher megapixel camera to take the exact same photograph; the higher megapixel camera can translate the analog details of real life to a higher fidelity. The thing about old movies is that the higher your scanning resolution the more apparent the various physical errors and imperfections on the film is, so the more post processing you might need to do.

With regard to film, as mentioned, there isn't really a fixed resolution that it was shot on. There are different sizes of film with various levels of quality. So, it's more a combination of what current scanner tech can pull out of a square millimeter, and how well the original lens/film/etc recorded information.

Far as I know, 35mm film could today be scanned at about twice 4K and support additional information being pulled from it. That said, if display fidelity can't reflect a difference, then there's no point. So while 4K may not be sufficient to actually record all the data we could possibly pull from a 35mm frame of film...it's more than enough to replicate how that film looks projected in a theater.

There are still plenty of things out there that were originally shot on video, or had the final output onto video, and can't have additional information pulled out of the source material like that. That'd include a lot of the fully-digital films, and the earlier ones of those (like Star Wars Episode II) were shot at 1080p.

Kodak put out an article about this several years ago. It gets into complicated math, but it really came down to the average piece of 35mm Nitrate Film stock being roughly 87 megapixels per frame. To put that in perspective a 1080p image is a 2.1 megapixel image (frame = image). Now that can be modified up or down based on ISO, type of film, resolve, and color density, but like I said, average piece. Now it gets weird when you look at different films. Say Wizard of Oz, since it was shot in three strip technicolor, so it was developed three times - Red, Green, Blue. So each frame could be 261 megapixels. Or if you look at Lawrence of Arabia, which was not shot on 35mm, but 65mm and when developed is 70mm, it could theoretical be 2 gigapixels per frame.

Truth be told, 4k and 8k are great for historical purposes, but most people cannot tell the difference between the same footage at 1080p and 4k at a standard viewing distance. Part of that is because most people do not color correct their tvs.

I bet you just love seeing all those overdriven contrast levels on display models at stores.

Back when I worked retail I would color correct the tvs weekly. Truth be told, I rarely go into a store that sells tv now. Most of my shopping is done at just Home Depot and Kroger.

Not a good sales practice. You only color correct the most expensive tv's so you can show customers why it's worth the extra money.

Sound shady?

I don't know many stores that do not use that technique for an up sell.

The problem with that is that properly calibrated TVs don't "pop" as much on the sales floor as ones that are overdriven to hell.
