Bo Hallen Posted June 16, 2016 Report Share Posted June 16, 2016 I am doing a couple shoots and am using a 5D mark 2 (not mark III) oon my Zephyr. I already have the Blackmagic mini converter for hdmi to sdi-4k, and use that with my GH4 and it was solid. But I am not getting a signal on my marshall with the 5D mark ii. I switched the settings on the converter to auto and figured I wouldn't have any problems. I had forgotten that on the 5D mk ii you lose the display when connected to an external monitor and that's ok. But the signal I do get is weak, even though it says signal strength 95-96% on the marshall. And weirder is that the intermittent signal I do have is a split screen of 2 of the same screen. I will try different cables and do some research on the converter box but was wondering if anyone has ever encountered this issue?? Any advice?? --Bo Hallen Quote Link to comment Share on other sites More sharing options...

Premium Members Peter Abraham Posted July 10, 2016 Premium Members Report Share Posted July 10, 2016 If the issue is signal degradation, buy a 12vdc powered Video D/A from B&H Photo. I use one on almost every job. It is THE CHEAPEST insurance protection against one item fucking up your HD video signal path. Before I thought of using this, I used to run my HDSDI ( if the camera only had one output ) out of the camera, down the post, through the Hyperdeck Shuttle, through my monitor, back UP the post to a Transmitter. Lots of chances for problems. And I had them. The BlackMagic Hyperdeck Shuttles have an issue where voltage runs into the video lines and voila- you have friend your monitor. Or transmitter. Or both. Well, enough of that crap. Now I use this tiny lightweight thing. 1 jack in, 4 outputs- each one HDSDI 1 volt peak to peak. Get one, use it on the outbound signal from your DSLR. Then you are using individual HD lines for each destination. This is the unit I own and use. Best, Peter Abraham, S.O.C. 1 Quote Link to comment Share on other sites More sharing options...
Premium Members Marc Abernathy Posted July 10, 2016 Premium Members Report Share Posted July 10, 2016 (edited) and with an 18 inch dovetail plate you can mount this sucker with ease... ;-) Peter, this gadget looks cool. did you make a power cable for it or did you purchase one? and how do you power it? Dtap? Edited July 10, 2016 by Marc_Abernathy Quote Link to comment Share on other sites More sharing options...
Premium Members Peter Abraham Posted July 10, 2016 Premium Members Report Share Posted July 10, 2016 Heh- indeed, I screw it into the underside of my Longplate. The metal mounting fins make it easy to grab with zip ties, etc if you've got to put it up higher. Like most of these smaller adaptors, it comes with the small ac/dc converter and a long cable. It had the usual 2.5mm cylindrical jack on the end. Meter the output to make double sure of polarity and then I cut it off and soldered a P-Tap jack onto it. I use a 1-4 P-Tap adapter on top of my sled. Wired into one of my 3 pin Lemo cables, it affords me places to power plenty of little bits that don't draw tons of amps. The issue of signal loss or infiltration of voltage into video signals or potential distortion of our primary HD signal has been a deep thorn in our collective sides for years now. You cannot use a T-splitter on HDSDI ( opposed to Composite, which you can split pretty easily with a usable signal ). This solution works for me and I will never again be running the outbound signal down my post, around through various bits and back UP my post to the Xmitter. 1 Quote Link to comment Share on other sites More sharing options...
