Sivaji - The Boss is finally releasing on 15th June all over the world. This biggest budget movie in India so far, is undergoing digital post-production now. This is the first movie in india to undergo scanning at 4000 resolution. The process is tedious as 4000 resolution is stored on files that are four times bigger, which have to be worked on and recorded back at the same resolution and the normal standard for the films are in 2000 resolution.

Prasad EFX is doing the digital post-production for 'Sivaji'. Under the standard process, colour grading alone, which is a part of the digital intermediate process, can cost Rs 15 lakh, said Mohan Krishnan of Prasad Group. Once the film shoot is completed, the 35mm or 16mm original camera negative (OCN) has to be converted (scanned) to a digital format, called the digital negative. The negative is then graded as a digital intermediate for further processing.

The scanner or ?datacine? captures each pixel in the film into a digital image, normally at a 2k resolution. 2k means each 35mm frame is 2048 pixels wide by 1556 pixels tall (2048 X 1556, approximately 2000, that is, 2k), which is 3 million pixels total. 4k is 4096 pixels wide by 3112 pixels tall (4096 X 3112), which is 12 million pixels total. Hence, the digital negative captured at 4k resolution is much more detailed and closest to the original negative, Mohan said.
