Atomos setup guide for the Panasonic GH4 and 10bit external recording

Though the Shogun has not yet been released you can still obtain one of the best HD signals available on the market from the GH4’s HDMI port. This is 10bit 4:2:2 and oversampled internally from 4K, a bit like on the Sony FS700 but for only $1699. The video above shows how to setup the camera for recording 10bit 1080p onto the Atomos Blade. In the next few days I should receive my Atomos Ninja Star which is a tiny low-profile recorder with no screen, for when you want to use the screen on the camera but benefit from the …

Exclusive: here is the first app to resample Panasonic GH4 4K 8bit to 10bit 4:4:4

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.

Discovery: 4K 8bit 4:2:0 on the Panasonic GH4 converts to 1080p 10bit 4:4:4

Panasonic GH4 4K

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 8bit 4:2:0 4K material from this camera can be taken through a workflow in post that converts it to 10bit 4:4:4 1080p – with all the smoother tonality, better colour and workflow advantages that format brings. This is a big leap for 1080p based on the much more expensive C300 which only does 8bit 4:2:2.

I asked Go Pro’s David Newman (Sr. Dir. Software – follow on Twitter) whether this theory was correct…

Panasonic GH4 in a professional setting – FAQ

Above: interview with Illya Friedman of Hot Rod Cameras, by Dan Chung

The GH4 is a consumer camera but one which has the most pro-camera leanings I’ve ever seen from a consumer or even prosumer model.

Because of that many professional shooters are considering the GH4.

Here then are some of the remaining questions from pros on the EOSHD forum answered…

Hands-on preview of the powerful 4K shooting Panasonic GH4!

Based on a pre-production model

Since the GH1 I have been shooting with Panasonic’s mirrorless system for video. Without this series of affordable cameras my early work as a cinematographer and filmmaker simply wouldn’t be the same. The GH4 marks a much needed major leap for the line, the first to shoot 4K to an efficient internal codec AND output 10bit 4:2:2 1080p over HDMI to an affordable external recorder like the Atomos Ninja!

On a visit to Panasonic I got to see the camera, see 4K sample footage and give my feedback. Here’s an account of what I saw…
