The reason why it's cut like that it's because it's a Behind The Scenes from the shooting of BBC's Earth. Normally you'd watch it after watching a specific episode (or even later) and you're not interested in particular content of the shot, but about the making of the shot. Hence the interview, rapid cuts and so on. If you see the full BBC Earth, the scene is a lot better and makes more sense.

Thanks for providing the actual explanation. There are (currently) four other comments with useless everything-used-to-be-better-cynicism, which make me pine for the web of yore, when more than 1 in 4 comments brought expertise and not faux-nostalgia.

That's the trend of these type of shows. While these types of shows can/could be considered educational content, they try to over dramatize them to make them "entertaining". They try to build up some drama/tension even if it is obviously forced. Then intercut with the limited video footage you have even reusing the same footage. There's a fine line to keep educational content from boring your viewers to tears and making it feel like sitting in a secondary school class, but the producers have not gotten it right yet.

That seems to be the trend these days. Videos are cut for emotional effect mainly. A lot of videos about race cars are like that. Quick cut here, quick cut there, cool sound, it sort of implies that something cool is happening but you never really see it. Same with the latest Marvel superhero movies. I watched Avengers and I couldn't even tell what's going on in the fight scenes.

I have to completely agree. Horrible video. I found a much better one that is very neat to watch the orcas do a coordinated attack. Check this one out: https://youtube.com/watch?v=AwbNRNCxhFg

They never got the seal. As smart as they are, I'm surprised they didn't have someone waiting on the other side for it to fall off.

Just watch the opening scene of The Graduate to balance out the frenetic cuts.
