Chrono Cross Opening FMV

This has bothered me for years, so I'm apealing ot the collective wisdom of the EoFF community.
In the Chrono Cross Opening FMV there is a clip where Serge levels his swallow (presumably at an enemy of screen) and charges forward, in what looke like Termina. Despite playing the games multiple times I have never seen this in game and have always been wondering where it is from.

YouTube - Chrono Cross - Intro ( English )
1:29 on this video.

It's simply exclusive to the opening. So is that shot of Harle leaping in front of the moons at 1:32 (and, if I recall correctly, the next shot of Harle at 1:35).

What a boring conclusion :p

It looks pretty though :p

It's one of my favorite openings.

No kidding. I watch it in it's entirety almost every time I play CC.
