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.

Revealed: Metabones EF Sony E-Mount adapter optically defective

Metabones EOS adapter on NEX 7

UPDATE: Metabones inform me they have fixed the latest adapters with an anti-reflective part. If your adapter suffers from reflections, if yours has any of the issues below, simply contact Metabones and send your adapter back for a service

As if the initial non-functioning firmware with the NEX 5N and NEX 7 wasn’t bad enough, it appears Metabones will have to completely re-design the recent EOS lens to E-Mount adapter.
