I have the BMD 4k 1M/E. I recently did an outdoor concert with it running 4 JVC HD GY series cameras, the closest was at a 150′ SDI cable run and the longest was at 300′.
The program out went to a BMD SDI Distribution (1 SDI in to 8 SDI outs). From there, 2 feeds went to these 40 feet long LED video screens (yes two of them, one on each side of the stage). Two additional feeds went to two BMD Hyperdeck Studio rack mount recorders for redundant recording of program. The last SDI out went to a mac pro laptop with a thunderbolt mini recorder running live streams software. We got internet in our production van using an ATT mobile wifi device which was enough for medium quality upstream.
BTW… my portable switcher racks have BMD scopes, monitors, tons of converters. The only non-blackmagic thing was the cameras, computers, cables, and 1 AJA ROI device which allows DVI to SDI input. the BMD box that does the same doesn’t scan convert so it’s pretty useless.
So, in other words, using BMD infrastructure, it’s possible to set up a seriously mean switcher rig that costs a fraction of what it would have 10 years ago.
I love BMD gear. My 2 cents.
