has a case study (Somewhat of a promotion for Blackmagic Design) on how a complex video production is done for a touring band for live shows.
Here’s a gist:
HDMI cameras were used as mini-cams throughout the stage, while seven HD SDI broadcast cameras captured the main performance. Each night Tom Levitt, in the role of video engineer for the tour, would take a line cut from a Blackmagic ATEM 2 M/E Production Switcher which was mixed using the ATEM 2 M/E Broadcast Panel. The ATEM was bought especially for this tour, not only for its broadcast-grade features and panel, but also for a significant factor in video for gigs, its one line video delay.
Thomas explained: “The one line of video delay is phenomenal. It’s extremely fast compared to other video switchers, which maybe have one frame delay, or sometimes up to four frames, which makes them unusable for us, other than for live relay. With the ATEM, we’re ahead of the game already. We can afford to add a couple of devices that add two or three frames of delay each and we’re still less delayed than other systems. By the time you’re standing twenty or thirty meters into the room, given the fact that sound travels slower than light, your sound has taken two or three frames to travel that distance anyway and it’s bang in sync. That was a big selling point for the ATEM.”
