A "real" 4k from a 5k - 6k camera

[Joe G.]

I take it that the real answer to my actual question is: 'we don't know until the things are farther along.'

It was a straightforward question about the measurable resolution of "5k" or "6K" sensors.

No sophistry was needed.

Measurable resolution will be somewhere in the region of 78% of the linear pixel dimensions, given similar OLPF to RED and assuming the lens is not the limiting factor. If any of those conditions change, that % changes.

To answer the OP, in order to achieve a pristine "True 4K" you're going to need 5- or 6K sensors. Better to err on the side of oversampling. That's why I'm so excited about FF35 @ 6K. It's going to result in mind-blowing motion pictures.

with regard to the film/digital issue i think it's always interesting to look at the audio world. Most of the development of the visual side of things has been reflected already in the audio side in recent years. Most audio pro's agree that analogue audio added a certain warmth to the recording which digital could not replicate. But now it is very very much fully digital apart from analogue ecenentricity. There was for a time a big surge in recreating the analogue characteristics via digital methods, and while they are not 100% equiv, the good ones are pretty damn close, and with their ease of use, without all the problems of tape, good enough for the majority of the industry to abandon them. At some point Film will be the same, and Red are seemingly going to be part of the breaking point!

Well as I've heard the flip over to digital is coming rather fast. A 12 screen theater down near Huntington Beach is going to change over to all digital by the end of this coming year...or so its been said to me. They already have a couple 2K's up there now.

Jim had some really solid points, as Jim often does, film is bad for the environment. Its crazy how much film is just wasted. Plus once those film prints are done they usually get cut up into little pieces so no one can use them. Plus they are usually so trashed from being out in theaters you wouldn't want to watch them anyways.

Also 28K down-converted to 4K will look amazing. I've seen 65mm down converted to 4K and that was some of the best 4K material I've seen.

Strange argument... we shoud also stop dragster races... and drive Hummer... :usd:

Hope we will be able to archive DATA for 50/100 years like we do now with film...

We are at a point where digital archiving will be problematic. A major that wants to erase a DCP or deny acces to the key will make the movie lost for ever. No hard copy that could be restored...

The manual about the DCP key is bigger than the DCP specifications itself.

There are still stuff do be worked out...
