By the way........what is 2K???????

[AlanW1980]

2k film res should be 2048x1556 with an aspect ratio of 1.316

It pretty much depends at what aspect ratio you're working at. "2k" ideally means 2048 horizontal, but there's no single standard for the vertical number of pixels.

i am currently working on a short film . We had different image sizes as sources . Some were 1920*1444, others were 2048*1556 . the scanner was different but its all going to be on the same film ....

i dunno :hmm:

1920*1444 is usually HD brought in from a Spirit. It's not really 2K, but Philips like you to think it is. 2048x1556 is standard accademy full app 2K. It is usually cropped to 2.35 super35 format for final delivery.

Most film scanners/recorders call 2K half res as they are designed to do 4K although most people don't because of disk space/memory issues.

Another common one is 1828x1556 (also confusingly called 2K) which is anamorphic cinemascope. This is stretched 2x to get 2.35:1 aspect ratio. This gives less film grain than super35 as it uses more film area, but you can get oval lens flares (eg Alien) and you need more expensive lenses. Plus in the composite some operations (such as rotations) can go a bit weird if you don't compensate for it.

The other one that often crops up (apart from Imax) is vistavision which is your normal 35mm stills camera format. In this case the 2048 length is often used for the vertical portion of the image. Don't think this counts as 2K though.

The reason why the anamorphic widescreen res is less in the x axis than full gate super 35 is to allow for the soundtrack strip that runs up the side of the print. Thta's one for all you film trivia fans out there...

Of course even if your target's 2k, you don't always need to render full 2048x1556. You can often get away with 1.5k or even 1k, especially if your shot's heavily motion blurred or defocused.
