Mac AVCHD gamma issues – the fix

FS100 with SLRmagic Hyperprime

As I recently found with my FS100 Macs really seem to hurt your AVCHD footage from Sony cameras and the Panasonic GH2… But especially the Sony FS100.

It is no wonder these cameras often get a bad reputation for limited dynamic range, crushed shadows and blown highlights – when you are only seeing the middle part of the full 8bit range of luma.

This Rec.709 portion of a 601 space (16-235 instead of the full 0-255 the FS100 shoots in) is incorrectly remapped to 0-255 by Quicktime. Therefore apps that use Quicktime at their core like Premiere, trip up. This makes a huge difference to the image. When fixed, you recover over 10% of your dynamic range, highlight and shadow detail, along with a much smoother roll off to whites and blacks.

How Mac OSX still *screws* your GH2 / FS100 / NEX footage – A must read!!

FS100 and GH2

I’ve had my suspicions for a while now about AVCHD footage having a different exposure on my Mac to on the camera. When I edit my GH2 and FS100 stuff natively in Adobe Premiere Pro CS5.5 or the new CS6, or preview AVCHD MTS files in VLC Player (Quicktime X still does not support AVCHD) blacks are crushed and the image is darker overall with far less shadow detail than on the camera’s LCD.

The iPhone came from nowhere and revolutionised the smartphone industry to such an extent that Nokia all but rolled over and died. It was a visionary move.

OpenCL in OSX Lion to give FCP X huge performance hike

Apple Mac OSX Lion supports OpenCL

OSX Lion is to have an emphasis on a technology called OpenCL.

OpenCL allows normal apps to take advantage of the programmable nature of GPUs (graphics processors) in modern computers. GPUs are more powerful than general purpose CPUs but until now have only been used to crunch through 3D graphics. The graphics chip has long since stood idly by unless playing games but now is about to have a lot more influence over your everyday video apps.
