I have been in a few situations recently where I needed to run signal over a long distance, between a HDMI sink & source. Mostly I have done this with HDMI over cat v systems but occasionally I have needed to this over SDI. When trying this with the Black Magic HDMI -> SDI & SDI -> HDMI Micro converters (all 3G versions) I have found issues where the signal makes it to the sink, but will randomly flicker if signal will come through at all.
Any pointers on where I might be going wrong on this would be greatly appreciated!
What is the brand/type number of SDI cable being used and what is the distance? Also, what format is being sent and at what frequency? 1080i, 1080p, 25, 29, 50 etc?
