You’d also think latency might be an issue, considering the amount of distributed sources. “We had to plan it carefully, and have a really detailed idea of what was happening on each end, but once we had that charted, we were fine,” Ruiz says. “With Viz Vectar Plus you can really accurately adjust delays on each source. It’s really powerful. “Also, since for this project we had all the discrete channels and somewhere else to deal with them, we could bring a mix down to the Viz Vectar Plus.”
vision mixer just had to activate them with a macro. It’s complex to set up, but once you have the macro, it’s very simple to operate.” Ruiz adds that the graphics integration during the Red Bull series, even considering the addition of home computer colour to the mix, was “seamless”. As for playout, this too “went really smoothly”. “One cool thing with Viz Vectar Plus is that it supports SRT,” he adds, referring to the open source video transport protocol. “So it’s pretty simple to send it to customers who are really demanding in
VISION ON It’s hard to picture a live production system without access to graphics, and the virtualised version present in Viz Vectar Plus is no different. “Viz Vectar Plus offers simple pre-existing graphics, but if you want really cool 3D live animated graphics, then you need something like Viz Engine for example, and you just bring the graphics through NDI. NDI supports alpha channels, so you
terms of encoding. For example, for somebody asking for multiple deliveries, to Twitch, Periscope, YouTube and private CDN, at the same time. In this case, we sent a really good-quality SRT to a server, then performed all the relays from there.” CONTENT FOCUS To date, since that first TVE quarantine show, Square One has carried out 118 remote productions with Viz Vectar Plus.
ONE COOL THING WITH VIZ VECTAR PLUS IS THAT IT SUPPORTS SRT
just grab the graphic as a source and that’s it,” says Ruiz. “If I don’t have a Viz Engine available, I can just call on [a freelance operator] in France and bring the graphics through SRT with 200ms latency. Another tool for the vision mixer is the composition preset feature, which lets you animate layers and overlay position, rotate and other attributes, as well as add animated backgrounds. “With the Red Bull battles, we had around 25 different preset compositions,” says Ruiz.“So the
“I think NDI is key,” he says. “But Viz Vectar Plus is a really balanced aggregation of useful tools. It’s rare that an operator will request a feature and we find it’s not there. For example, Viz Vectar Plus manages DDRs really well in a comfortable way for the operator, macro automation is there, downstream key [DSK] management is there. And all the functionality is focused on content production. It was an absolute game changer for us.”
