John Brawley posts new Blackmagic Cinema Camera footage

Please note the compression and noise is from Vimeo not the camera

John Brawley has some new Blackmagic footage for us. Unfortunately Vimeo streams 1080p at something like 7Mbit and John has no download option on this clip, so watching Blackmagic footage when it is so heavily compressed rather defeats the object of such a lovely 12bit raw camera.

Nevertheless dynamic range and resolution are looking pretty good.

Mac AVCHD gamma issues – the fix

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.
