Why Choose Sony's X-OCN? A Brief Guide
X-OCN has been around for a while now but people don't seem to know much about it...
You require Sony's AXS-R7 to record it along with AXS Media, these fit the PMW-F5, PMW-F55 and the new Venice. But the media is so expensive I hear you say! An AXS-A512S48 Card for the R7 has 512GB space and costs £1,390.00, so £2.72 / 1GB A SxS Pro+ 128GB card costs £745.00, so £5.82 / 1GB The AXS card is less than half the price of the SxS Pro+ card when comparing data. X-OCN (or eXtended tonal range Original Camera Negative), if you like, it's a form of compressed RAW but doesn't compromise on picture quality as X-OCN is specifically processed and optimised for Sony sensors. There are two flavours of X-OCN, Standard and Lite; Lite is indistinguishable from Standard visually. Sony's RAW was already 16bit and the same for X-OCN. Arri's RAW is 12 bit and Apple's new ProRes RAW is 10bit. Colour Depth:- 10 bit - 1,024 colours
- 12 bit - 4,096 colours
- 16 bit - 65,536 colours
