These early FMV sequences were taken from sonics.mpg, along with other material. It shows some early development of the Sonic Shuffle FMV sequence. You can see here that in the original sequence Sonic flies down a green building.

This is from the final sequence, and as you can see, it's yellow. The top part is actually green, but as soon as it goes to ths camera, the rest is yellow.

During the sequence where they warp into the Maginaryworld, there are closeups of each character. Tails looks unsure in the prerelease version.

In the final, Tails has a smile on his face, and the camera has panned back to view more of his face.

In the pre-FMV there are second long shots of the following cast members. here though Tails has an awkward looking smile on his face, and his eyes are looking towards Amy.

In the final, Tails smile is the same as the one used during the warp, and his eyes have straightened.
