So the auditorium shows are done with the ATEM 1/M, we connect the ATEM's output to the coax run to the studio, and have it connected as an input in our 40x40 smart video hub. We have two locations in the building: our auditorium has 5 HD-SDI drops that lead to a single panel in a room, and that room has 2 HD-SDI runs to our TV studio. So this is the larger picture of where this converter fits in. Shouldn't the indicator lights on the component side of the converter light up if they were working properly? I will try cycling power just to check.ĭenny Smith wrote:That said, you may need a monitor connected to the analog out, to see the setting you are getting with the dip switch I've been using a samuari blade to text if a composite signal is coming out, but I do have a component monitor that I'll try next. I did not try cycling power in my test yesterday with the new second unit, but I would think if it powers up the first time with the DIP switches set that it would be good. I have an image through the recorder into Blackmagic Express on an attached PC, so I am confident the SDI input to the mini-converter is correct since it loops through and successfully feeds the H.264 recorder box. Then it loops through the mini-converter and the SDI-OUT of the mini-converter goes to a Blackmagic H.264 recorder. The SDI-IN to the mini-converter comes from the SDI PROGRAM OUT of the ATEM Production Studio 4k. Also tried it on another connection and verified the composite cable is good.įor the SDI signal, I am using the SDI-IN and SDI-OUT loop on the mini-converter as follows. I checked the composite video cable with an ohmmeter to verify it was good. On my original unit that I exchanged I did try cycling power after setting the switches, but that did not help. Since this was my second unit, I set the DIP switches before ever powering it up for the first time. The specs say the mini-converter supports 1080p 59.94 signals on SDI, but can it not downconvert that format to analog SD composite video?ĭoes anyone have an idea why I can't get an SD composite video output from the mini converter when feeding it a 1080p 59.94 signal via SDI? But I still get no composite video signal. Thinking the first mini converter might be bad, I exchanged it for a new one. I have an SDI signal lock light and the POWER light, but I get no signal out of the composite BNC connector. I have DIP switches 1 and 5 set to ON in the Mini Converter and all others DIP switches off. So far, I get zero output (yes, I've tried another monitor straight in to the composite video input without the twisted-pair adapters so they were out of the loop, but still get no video). I purchased a Blackmagic SDI-to-Analog converter thinking that would do the trick. Because I don't have an SDI cable in place for that feed yet, I wanted to downconvert an 3G-SDI output from the switcher to SD composite video and feed that over the existing twisted-pair adapters. There are two flat-screen TVs in the choir loft that formerly received composite video over via twisted-pair adapters at each end of the 160 feet long connection from switcher location to choir loft. This was an upgrade from an old NTSC SD system. I am currently forced to use 1080p 59.94 as the PROGRAM OUT from the switcher (due to camera compatibility issues). Our church as a new ATEM Production Studio 4K. But if there is something cheaper that will give me stable signal, I'd rather do that.I am on my second SDI-to-Analog Mini Converter, and both exhibit the same symptoms of not providing a down-converted SD composite video output. I'm considering trying the 6-input ATEM mixer, which is about $1000, simply to see if it will give me smooth, stable output, even if the vertical interval on the one input keeps jumping around. the big ATEM mixers are massive overkill and way out of budget. I need 16-20 channels for this, and really just need simple, remote input switching. It had the added benefit of maintaining output signal, even if the router toggled to a malfunctioning camera. In an analog version of this setup, we had a cheap composite video mixer that took care of the vertical interval mis-alignments when switching between non-genlocked sources. Are the HD-SDI Timebase Correctors? Is there some other type of gear that can help here? Is there any device I can insert downstream from the router (I'm only using one output) to stabilize the output video? I don't care of I get a black frame or two as it re-aligns the non-synched signal, just so long as it doesn't register as an interrupted signal.
