Movie with huge timeline

Hey all,

I’m a bit of a flash novice - have a decent understanding of how it works, but never done any really large projects. Most of what i’ve done have been small flash banners for sites and that kind of stuff.

I’m doing a larger project now that will involve a very long timeline. The entire movie will probably be around 5 minutes. How would you guys approach it? Would you keep it all in the timeline and create one large timeline or is there a more efficient way of working on a large flash file like this?

Would appreciate any help / advice you may have,

Thanks
