It is clear in the video you need a runway He said it could take off from a football field and clear the stanchions. It evidently needs a 300 foot unpaved field and a bit of space around it without anything exceedingly tall. That's pretty good performance, and you can get by with a lot less than a proper runway, but it can't take off from a traffic jam.
