[vimeo]http://vimeo.com/90683855[/vimeo] A few days ago Thomas Worth of Rarevision (5DToRGB and RAWMagic) asked me for some original files from the GH4 so he could develop an experimental app he had in mind. The result is an embryonic new command-line app for the Mac, which takes 8bit 4:2:0 4K H.264 files from the GH4 and resamples them to 10bit 4:4:4 in 2K DPX format.

The GH4’s internally recorded 4K files can be converted to a chunky 2K 10bit ProRes 4444 image which grades extremely well. To test this theory I call on colourists to have a go at it. Arri Alexa ProRes files are available from their FTP server. Details below.
Pros are wondering what the benefit of 4K is to them in terms of overall image quality, when mastered and delivered for 2K / 1080p. A lot of work is still shot in 1080p and cameras like the Canon C300 are the workhorses of the moment. In the case of the GH4 it may appear from the specs that it’s just an 8bit 4:2:0 camera internally. Actually the theory is…

In the early days of DSLR video the codec was probably the weakest part of the camera. With the advent of uncompressed HDMI out – the codec is no longer a weak point but sensor sampling becomes an Achilles Heel. Can the Nikon D5200 benefit from a hike in image quality from using an external recorder?

It was a clear day and the results are just as stark. Download the full 2.5K shootout video. Here’s my verdict on which camera you should buy – based purely on image quality. The following cameras are in this test: Blackmagic Cinema Camera (retail) Panasonic…
There’s some debate at the moment around the Blackmagic Cinema Camera and how useful the raw recording mode is. For me it is ground-breaking at this price point but it seems not everyone sees it with the same enthusiasm because of the workflow and storage requirements. Some say raw is time consuming, not practical, or clients don’t need it. There is no single answer to this which suits everyone, or every…
