Surprisingly people are not afraid of their lives and seem doing crazy things: Death is in front of them, yet some jump up and down from joy, some walk at ease, while buildings and cars are thrown at them, some...

Someone in the comments mentioned it's from a movie "Into the Storm", a movie about storm chasers.

Interested by this, I looked it up. The footage happens around 26:09 seconds into the film.

I do not understand what you are saying. Those links do not make too much sense if they are to prove the clip is fake.
In case if by film you insinuating that the footage is made up, I do not believe so. It seems pretty real to me. How could those trucks on the air, those building coming down, be fake? And if even they are, do you know how much would be the cost of this few minutes ? I guess it easily could scale out the cost of the Waterworld movie and to me, it would be illogical and unheard of, spending this much in a film that is not much advertised.
But assuming if it is footage of a film, still this do not prove they are fake totally, because producers often incorporate real footage in the movies specially about natural disaster.

The budget for the movie was $50 million dollars, $23 million dollars was used for CGI.

Here's an article that includes an interview with the director: https://www.mnn.com/earth-matters/climate-weather/stories/how-real-is-the-new-tornado-flick-into-the-storm.

An excerpt:

"Quale, who created these scenes with a mix of practical and computer-generated effects. "We'd have actors working with practical effects in the foreground — the wind and rain near their face is all real — and the tornado in the background is digital. Almost every shot was augmented in some manner with visual effects. For the sequence in the storm drain, we created a wind tunnel. We had two 100 mph fans going at full blast."

Thanks. Now it makes more sense.
You are very resourceful in these, aren't you?

We saw the movie the storm it was really very realistic with amazing affects. Definitely freaked us out when we saw it because it was so brilliantly done and so realistic you really felt you were there with them.
