Asking someone you don't know for 60 seconds on camera is one of the highest-leverage moments at a trade show. One short clip with the right person reaches more buyers than the dozen badge scans you collect in the same minute. The hard part isn't the camera. It's the verbal ask. Get the framing right and most people say yes.
Pro tip: Frame the ask as "a quick series we're filming today." That single phrase turns a cold approach into a participation invite.
Why "a quick series" beats "can I interview you"
"Can I interview you?" sounds like a commitment. People hedge. "We're filming a quick series today, want to be part of it? It'll take 60 seconds" sounds like an invitation. Series framing implies others have said yes. Sixty seconds caps the time risk. Most people will participate when both anchors are there. The verbal ask matters more than the camera, the lighting, or the location.
Give them the question before you hit record
The worst clips happen when you ambush someone with a question while the camera is rolling. They freeze, they ramble, they say something they'll regret. Give them the question 30 seconds before you record. "I'm going to ask you one question. Here it is. Take a second to think, then we'll roll." That single beat of preparation makes the difference between a clip you can post and a clip you delete.
Use implied-consent language so legal is covered
Before you hit record, say one sentence on tape: "By giving your answer on camera you're giving us permission to use the clip on our channels." That's implied consent and it stands up. You don't need a paper release for a 60-second clip taken in a public trade-show environment. You do need the spoken consent line recorded. Make it part of the script, not an afterthought.
Close the loop after the show with the finished clip
Offer to tag them in the post when you publish. Get their handle on camera or write it down right after. Then actually do it. Send them the link to their clip when it goes live. That single follow-up turns a one-time contributor into someone who'll say yes the next time you ask, and someone who shares your post to their network. The follow-through is the asset, not the clip itself.
Try it this week
At your next event, write down one question you'll ask everyone you stop. Practice the series-framing ask out loud before you go. Bring your phone and a lav mic. Aim for ten clips on day one. Most will say yes. The ones that say no would've said no to anything. The ten who say yes give you a month of content that no badge scan can produce.
