Sony's X-OCN Media On DaVinci Resolve, Adobe Premiere Pro, And Final Cut Pro

 DaVinci Resolve and Adobe Premiere Pro can open Sony's X-OCN Media, but Final Cut Pro cannot... At Least Without A Media Extension.

Resolve, OK.
Premiere, OK.
FCP sees and import the XAVC clip just fine, but does not understand and cannot import the X-OCN clips.
X-OCN clips are a no go for FCP (v11.2) as-is.

 X-OCN (eXtended tonal range, Original Camera Negative) is yet another codec developed by Sony in their high-end camera line. Here is Sony's X-OCN page for more details.

It supports up to 16bit video in a variety of compressions, and playback is not computer intensive, so it checks all the boxes, or so it seems.

See this article by Newsshooters.com for a detailed explanation of X-OCN.

Sony's own Catalyst software opens X-OCN, but I don't like Catalyst, and one would use it to convert the X-OCN footage to something FCP understands, say ProRes. But really it's an unnecessary step considering the nature of X-OCN.

X-OCN Clips open as expected in Sony's Catalyst Browse (the free version)

Note that, as deplorable as it is, for Sony Catalyst to read XAVC H-I HQ, it requires activation with a Sony Camera Model + Serial Number. Remember that all three NLEs read and Import the XAVC Clip just fine... As an editor I find this move pretty stupid.

But Catalyst Browse does not want to open the XAVC clip... ???
Camera serial number required. Yeah, sure Sony, I'm an editor.

Anyway, back to what we are trying to achieve, import X-OCN into FCP.

Resolve and Premiere are perfectly happy with X-OCN clips, and open, import, and work with them just fine. Final Cut Pro on the other end does not understand the codec.

Supposedly there used to be a Calibrated{Q} Sony RAW Decode plug-in that one could buy that allowed FCP to understand X-OCN, but it has been discontinued.

Enters Nablet Gmbh and their X-OCN Media Extension for Apple macOS. Currently in version 1.1. It's downloadable here, and is free for the time being.

Nablet's X-OCN Media Extension downloaded and ready to install.

Read this FCPCafe article detailing how it works.

And here is the Apple documentation about Media Extensions if you are interested.

I will be installing and testing it in incoming posts, and I will try to show the similarities and differences between DVR, PP and FCP+NME. Stay tuned!
