All tests based on pre-production model

Here we come to some areas which aren’t perfect on the GH4, but which nevertheless are both a step forward from the GH3. I like what Panasonic have started here with 96fps slow-mo. This is the first consumer camera to deviate from the video standard of 60p to give us a genuinely useful creative tool which sets the ball rolling for improvements in future models.

Nerd alert!

I’m afraid it’s time to put the creative urges to one side and get down to the nitty gritty. Just exactly how does the GH4′s image stack up against the competition?

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…

This test was conducted jointly with my good friend and neighbour Rudi at Slashcam – you can read his take on it in German / in English.

In the battle of the 1080p cameras, the game has changed. Here’s how the 5D Mark III in raw recording mode compares to the best 1080p output from the Canon C300 and 1D C.

The spec sheet is impressive. 14bit linear bayer raw is sub-sampled from a 6K sensor, giving 1280 lines of extremely clean resolution with an anamorphic compliant 4:3 aspect ratio.

This is in a similar league to the image quality of the Sony F35 (Superman Returns, Tim Burton’s Alice In Wonderland) which cost $250,000 just 5 years ago.
