well it could be done a couple ways.
1. you could try and mess around with trapcode’s particular. it is a has some interesting tools that can copy the old ipod commercials.
2. i think they maybe they had a 4-8 digital camera dolly rig with digital still cameras that had apature settings so you could get that streaked video look and they simple just turned the cameras on to take a photo every half second or every second as the dolly made its way around the circle track.. also the rig that held the cameras would be curved in the same way as the dolly track so that they all looked like they were taken from the same point. this is a cool idea it look very hip and trendy. there was a Japanese artist i saw about 8 months ago that did a really cool video using that light effect. you now are seeing that same look in the commercial for the new at&t adds. just still shots in a tiff sequence in ae… hope that helps.
