Peter, I stand corrected. The HDMI spec has evolved and continues to adapt to work with 4K and 3D signals. Unfortunately, so do the connectors types that are required to support these higher data rates................
.
Is nothing about the connector but about the specs.
The average HDMI we are using is 1.3.
This supports 10 Gbps transfer that means that is able to run 3 x 444 streams.
Is like 6 folds faster than a single SDI.

From Wikipedia:
Version 1.3
HDMI 1.3 was released June 22, 2006 and increased the bandwidth to 340 MHz (10.2 Gbit/s).

The only problem with HDMI is the crappy connector.

Dear Lance,

It is nice to hear that you are interested in the Gemini 4:4:4.

Our Australian Distributor, New Magic, is very interested in the Gemini 4:4:4.

I feel that their dealers in Australia will be very interested also.

So, just contact your dealer and express an interest.

The main problem with HDMI is that all connectors are 8 bit on cameras. And I even wonder if the Ki Mini and Atomos actually use 10bit HDMI parts as these parts are very sparse.

Hi Steve,

Though this is true of now although I am sure you know that the specs do allow deeper bit depths. The camera manufacturers just haven't implemented it yet and they wuled need the codecs to take advnantage of the extra 2 bits and very few pro cameras do 10 bit codecs either. To be fair we have only just started seeing 10 bit monitors/LCDs appearing in the last few years so take up is slow. In case you may not be aware there is debate as to whether the Sony FS100 may have 10 bit HDMI. A few quoted sources suggest it may be.

I really hope it is 10bit but that is not like Sony to be a pioneer.

The FS-100 has 8 bit HDMI. Confirmed from Sony.
