What does it mean by "Visualised by Ayumi"

[Delirium-Zer0]

Nah, the specific shots & edits are all the director & editor. (Usually the director will decide when things are seen, and the editor just has to get that timing right. On the TV broadcasts, it's aaallll the director and that's a tense job).

And devilayu's dead-on about typical artist involvement. Any singer, especially one who's really established, always gives alot of input on the concept of any music videos, concerts, costumes, photo shoots, album covers... They usually pick people who share their vision to work with.

In the case of concert dvds, it might be ayu's idea to do a certain thing for the intro (though judging from the VERY different types of intros, i doubt it), or it was probably her idea to show off-shot during Arena Tour & Stadium Tour 2002. That sort of thing.
