I used Blackpool as an example, a picture of any UK beach would serve the same purpose.

And if you're showing a snippet of video, simply to show he's at a beach it is equally as time wasting as if you are only showing a snippet then a picture really would suffice and you wouldn't waste time faffing about with setting up a video clip.

The only times videos have a place in a classroom is when they are being used to teach a grammar point. Or an advanced speaking or listening task. Not for showing low level learners what a beach in the UK looked like 20+ years ago!
