Picture (“Buddy”) courtesy of James Miller, inset – the CYP 4K HDMI scaler

The picture above (click for 1080p original) is from the 4K full frame sensor inside the Sony A7S (ISO 3200, S-LOG2).

Internally the camera does a simple downscale of the 4K signal to 2K for standard 1080p XAVC or HDMI recording – but James discovered adding a hardware scaler on the end of the 4K HDMI signal results in a more detailed 1080p image which is light and day different. The great news is this scaler is only £167 in the UK.

Add to that an Atomos Ninja Blade or Ninja Star for taking the image from the scaler and recording it to ProRes – and you have one of the best 1080p images available at any price.

This began as a 10 point list. It grew…

I am huge fan of the 1D C’s image but not the camera itself and especially not the price. The 1D C when it was introduced offered an absolutely lovely image and still does but now the playing field is rapidly changing.

Exactly how does the Sony A7S compare on paper to the 1D C?

The Sony A7S is the camera I am most looking forward to in the coming months and although it is a shame it lacks an internal 4K codec, it does promise much improved internal 1080p and 4K HDMI output. Here Yosh Enatsu has used the Blackmagic HDMI to SDI Ultra HD converter to a Hyperdeck Studio deck to record this test shoot in the dead of night.

I’ve been trying some run & gun shooting with no rig, just a gorilla pod and GH4 all handheld.

In the process I developed three image profiles for the GH4 which I’ve assigned to the mode dial on my camera.

This is the first footage to show what the GH4 is capable of with the EOSHD Cinema profile.
