This uncompressed 4K HDMI to USB 3.0 adapter may allow Android smartphones or tablets to work as field monitor / recorder

Inogeni HDMI to USB 3.0 converter

HDMI monitor manufacturers continue to miss a trick by not building an ultra thin monitor the size of a smartphone (or phablet) with build in battery rather than a bulky brick-like Sony NP block on the back of a chunky monitor.

Now a solution might be at hand to turn your existing Android smartphone or tablet into an HDMI monitor and even recorder.

James Miller adds £167 hardware 4K scaler box to Sony A7S with stunning results

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.

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 …

GH4 4K HDMI

Picture: EOSHD Forum, by Orangenz

Panasonic have confirmed that the GH4 (quite amazingly) outputs 10bit 4K 4:2:2 from the onboard micro HDMI port without the YAGH external HD-SDI unit.

However there are still benefits to using the HD-SDI outputs.

Here I have more details on how this whole thing works and what external recorders might be in the pipeline to offer 4K recording on the GH4…

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…

ProRes vs ProRes – A first look at uncompressed HDMI with the Nikon D5200 vs the Blackmagic Cinema Camera

D5200 ProRes test

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?
