No Video from Teradek Bolt 500

PostFri Apr 13, 2018 3:03 pm

A little background first... we're using a brand-new Sony FDR-AX53 camera, connected to a brand-new Teradek Bolt 500. The Bolt receiver is connected to a Livestream HD550 box (which has 5 Mini Decklink Recorder cards in it). Everything is set to either "same resolution as input" or 720p60. Everything involved has been updated to the newest firmware/software/driver version (as of this morning).

The problem is, the Livestream box doesn't show the video from the Bolt. I've tried in both Black Magic Media Express, and Wirecast, but I rely on Wirecast since I'm more familiar with it. Here's what I've done to rule things out:

    Camera - I've plugged the HDMI output directly into a Samsung 4K monitor, and video appears fine. I've also plugged the HDMI output from the camera into all of the Mini Decklink Recorder cards in the Livestream box, and video appears. So the camera is definitely not the problem.

    Bolt 500 - I've plugged the HDMI output directly into the same Samsung 4K monitor, and video appears fine. I also plugged the HDMI output into an older Sharp 1080p TV, and video appears fine. I verified that both the Samsung monitor and the Sharp TV are receiving 720p60 signal (via the "information" info on each display). So the Bolt itself is definitely not the problem.

    Decklink - I've plugged the HDMI output of the camera into each of the 5 Mini Decklink Recorder cards, and video appears correctly. However, when I plug the Bolt 500's HDMI output into any of the 5 cards, no video appears. No menu appears. No information appears. There is nothing that appears at all.

    Cables - I've replaced all the cables involved 3 times, with different lengths and brands, just to rule out any cable shenanigans.

The only conclusion I can possibly draw is that the Teradek Bolt 500 is not compatible with the Mini Decklink Recorder. I've opened a support incident with both companies, but I'm on a bit of a time crunch (I have a major event coming up that we need to record using this setup), so I'm hoping someone has seen this, or can offer suggestions on what else to try... Any ideas?

I don't use Livestream, but I do use Teredek Bolts. I haven't ever had this issue in places I have used them. I am going to hazard a guess that maybe you are 60p on some stuff and 59.94p on other stuff, and are having an issue there. Maybe. Try a Decimator MD-HX inline, scaling the output to 59.94.

Since livestream studio is running on your system, a few questions:
At settings - inputs (upper right corner): do you see all bm recorders? The hdmi input?
At the input setting (left, middle) you can choose an input, there you find convert (or similar, I dont have a system here: if you choose 720p60 or 720p59,94 instead of auto, do you see any signal?
