Did they shoot this with a drone?

It would seem so, but the cinematography uses the drone expertly:
* The camera is slung low on the drone to keep the props' shadow off the lens.
* The long angle of the shadows keeps the drone's shadow out of frame.
* In the few cases where the camera is looking away from the sun, the drone is in the shadow of a building.

They really seem to have outdone themselves this time in terms of rehearsal and extras, at least. The song...meh.

Technically this is crazy impressive. The drone operator and camera operator have to be stupid talented. The coordinator and choreographer for this should get crazy awards. I agree that the song is meh, but OMG is the video impressive. I would love to see behind the scenes on this. BRAVO!

No this is not technically crazy impressive. This is just plain crazy impressive. Don't need no technically.

Holy shit. My draw jopped at 4:02 and flayed on the store. And I can't even ripe tight.

If there's any after effects in this, I would be seriously disappointed with OK Go. They've "kept it real" so far, and I think post cheats would be horrid.

I was just thinking of a way to do the human LED board.

What I figure is little wifi-signaled lights to each umbrella holder. ON means open the umbrella, Off means close it. Then all the people have to do is hit their marks (the tape crosses and lines on the ground) and follow what the light shows.

By my count there are 2328 "pixels" in use here. The clapper at the beginning stated take 127. That's one hell of a huge production.

Always entertainingly inventive.

And it looked like it was taken just at sunset, probably at the end of a VERY long day.

The precision astounds.

Good choice selecting 2,324 Japanese people to be your pixels. Their precision and dedication to exactness astounds.

That final scene is mind-blowing, but has the problem of being so good that it starts to feel unreal. Seeing the making of and video from on the ground will be fantastic.

Mindblowing. Just... mind... blown...

Needs a *ftw. Damn - this is epic!

Adding video to channels (Ftw) - requested by Zawash.

Too bad the song sucks.

Come on guys, this thing has CG all over it! Look at the compositing at 0:50 when they are coming out of the building - they are floating all over the place in movements that don't match the camera. The dancers are obviously sped up many times while the band members are not. The clouds at the end come in awfully conveniently when the camera pans upward. Etc.

According to Rolling Stone, it was stitched together from 44 takes, so that might account for all of that. I'm a bit skeptical that the umbrella animations at the end weren't completely CG, but we'll see for sure if they release a behind-the-scenes.

Astonishing stuff. Gleeful. And I like the song! It's funky, catchy and cool. Far from meh. There's stuff out there that's hugely more meh, makes more money and doesn't give the world a fantastic video to love.

Actually the rolling stone quote is :

The grand finale was stitched together from 44 separate takes (using 2,328 people), but the high-tech editing doesn't diminish its visual impact.

As long as long as grand finale means just that last LED sky shot I don't think it takes much away from the accomplishment.

Here are a few statements from the director:

Other than some time warp, no indication that they used CG; just a lot of detailed choreography
