-=Secrets of Sonic Team=-

The beginning of the video begins with the original Sonic Adventure 2 Logo, showing off the light and dark sides you would play in a logo quite different to previous logos.
Here Sonic site breathing heavily in Green Forest. For some reason his torso is heavily darkened for unknown reasons.
Here is Sonic busting through a few crates, only he's in Sky Rail, a level in the final occupied by Shadow and not Sonic. Sonicteam didn't want to provide too much of the story for the game at the time, so they kept Shadow a secret. Since Sonic & Shadows movements are very much alike so they were able to switch him in.
Again, Sonic in Sky Rail at the very beginning of the level. This was the first showing of any sort of rail riding in a Sonic game, City Escape only showed the Truck sequence in the beginning.
This dynamic camera choice makes the camera turn 180 and face Sonic has he sky rockets through Sky Rail.
Here Sonic is talking in an unknown animated sequence. It's the first to show off that Sonic has seperate fingers, but also shows his new mouth position, which looks strangely odd in this scene. It looks quite blurred and like a texture.
A Small segment of the movie is froma camera of shoe height moving along Green Forest.
This is another small sequence where he points at something. This camera is different to the final where he uses a similar animation to callout Shadow, the area it's shot in is different to the final place of the Sonic/Shadow duel.
Like the Green Forest sequence beforehand, this is going through the first Eggman level on a ground level camera.
This was the first image of Shadow avaliable to the public, before he was named or even mentioned. Nobody quite knew if it even was a different hedgehog because of the darkness of the video, but many were skeptical because of the red stripes.
