What is the Best HDMI to HDSDI Converter for the 5D Mark II?

[laps03]

I have looked at both the AJA 5V DC and Black Magic 12v DC adapters. I am looking for the smallest compact way to get an HDSDI out from the camera, and in a way where I get the least intermittent drop outs. I have had real trouble with the HDMI port on the 5D Camera and getting a setup that would work on set for both the DP, and director.
Also a way to power the adapters is important as most Steadicam sleds have 12v and it is more common power to access. 5v DC is a little bit tricky, but I am trying to find a good solution for powering the AJA for longer periods of time.

Any help would be much appreciated...

I have attached a link to a Black magic adapter that I found on AbleCine seems a bit to big.

Here is a solution that may work quite well for you - if you are using a rig - you could velcro or mount the Brite-View AirsyncHD to the back of your rig like this:

the AirsyncHD has hdmi passthrough so that you can use an onboard monitor to operate the camera.

The receiver side can plug into a TV or monitor with HDMI input, or an HDMI to HD-SDI converter.
I have tested with an AJA and a Blackmagic on the receiver side.

You may be wondering - hey where did he get that regulated battery plate for the AirsyncHD?
It takes LPE6 batteries. They run the unit for a little over an hour each.

You can order the airsyncHD directly from Brite-View, and I sell the battery plates for $200/each.

The only downside (and this is a fault of the 5DII, not the airsyncHD) is that when you hit record the monitoring resolution drops to 480p from 1080... this results in a 2 second pause as the monitoring path adjusts resolution and confirms. So - roll pause one two speed is the pace of the resolution switch. Not a big deal - but worth mentioning.

Thanks!

a cost-effective alternative to the above is an HDMI active splitter. it's not quite HDSDI but it's very small (2.5 inches square x 1 inch thick) and it gives you and the director separate monitors.

they run on 5vdc. i've found that 3 AA batteries (in a cheap plastic pod from Maplin (UK), or Radio Shack (US)) will run all day.
the down side, like the AirSync, is that there's a 2 second pause whilst the signal is adjusted.
on the plus side - an HDMI to DVI-D converter turns any flat panel computer monitor into a big HD video monitor so the director kept happy.

The biggest plus with going wireless is that there is no cable to trip over.

If you break 10 cables (Which we can place a median value of $10/ea on) in a year that's $100 that would go towards a wireless solution that offers several additional benefits. The problem with hdmi is that it is a fairly fragile parallel interface, if one of the between 19 and 29 conductors is damaged your picture is compromised...
