We recently purchased the ATEM 1ME 4k for our church, and are very happy with it. Leaps and bounds over our BroadcastPix system.

It is setup as an SD system because not our cameras are HD... yet.

But, we cannot find a way to get the ProPresenter to feed as the DSK. Well, not always. Why ProPresenter as the DSK? We use PP for our song lyrics. Copying the PP show to a separate computer for our lower thirds on video streaming is easy.

1. We connected our 2008 Mac tower song lyric system, via SD SDI, and it worked great. But that system is for the house screens, not video.
2. We connected my MacPro laptop via mini display port to HDMI and it didn't work. Mac would not go down to 480i. Only 720.
3. We connected a loaner MacAir laptop with the same cables, and it worked great at 480i. But it was a loaner and the screen was too small. So, we concluded 480i was the answer.
4. Today we installed a new Dell tower system with Win 7 to it, via a USB2 to HDMI adaptor, and it would not work. Dell system only had two display resolutions, both way above what BP accepted before.

Please someone smack us over the head and tell us what we are missing. We can't keep swapping out computers. I am afraid to go buy another computer to find it wont work. Adaptors rarely tell you what their lower resolution is (480i), neither to computer mfg.

I know it's "more correct" to run everything at the desired resolution but sometimes it's more trouble then its worth. Just get a scaler and call it a day. What is important is that everything is at the same aspect ratio, resolution is not nearly as important.

you can use most any computer with dvi/hdmi/displayport (with hdmi adapter) and get an hdmi to sdi mini converter and use the processing dip switch which would allow you to use when you finally upgrade and still use in your current situation ... hdmi/displayport devices will also carry embedded audio ... dvi will not but you can use analog audio in that situation.

Thanks for the advice.

TvOne HDMI scalers are fairly cheap with decent quality output, plus, I personally prefer analog audio from the source to the mixing desk as it gives you more control than the BMD digital audiomixer.

to the DSK with ProPresenter 5 must buy the alpha modules Keyer DeckLink 4K Blackmagic card and Extreme or UltraStudio 4K
