Go back to my post in this thread, I believe it is post number 12. Follow my link to another thread here on MT where I explain a lot about this. If you read my comments there, a lot of this should be a bit more clear.
There is a difference between the "game" of capoeira which is what is usually seen in the roda, and actually fighting with capoeira. Most people today train for the roda, and not to actually fight. It's a bit like being a padded up tournament tag/touch player vs. a full contact fighter vs. someone who trains for purely self defense. Not the same thing, but different aspects and avenues that the same art can travel down.
Fighting with capoeira would be like fighting with any other art: straight forward, ugly, spontaneous, short, nasty. There would be no fancy moves, no acrobatics, no elegant flips and body positioning.
What is shown in this video is the roda, the game of capoeira, that got ugly and turned into a fight. I agree that most of what was seen was sloppy and not very effective. This is because as I mentioned, most people train for the game and not for the fight. But nontheless, it was still capoeira. To say that even Capoeira practiconers don't use Capoeria when they "fight" is a complete misunderstanding of what capoeira is, how it developed, what its history is. I'm not surprised by such comments as most people, even capoeiristas, are largely ignorant and have a very unrealistic understanding of the history of the art.
But what you saw on that video was still capoeira, tho it was sloppy and not skilled and not very effective.
