Not usually, items outside the screen aren't usually "rendered" unless
you have filters applied to the entirety of the thing or there's
something else forcing them to do so.
Using scrollRect can also really help you combat most manners of
framerate loss specially with big objects or images. Complex movies with
no scale/rotation transformation can also benefit from cacheAsBitmap.
But that's just academic talk. You should just try and do it. If/when
it's too slow, then you'll have to look into what'll make it faster.

would making items offstage _visible = false help with this?
the clips won't be complicated to be honest but they will be plentiful -
when zooming (1 level of zoom - i'm not a masochist) i will have 100
points plus the tick marks on the timeline plus the backgrounds (flat
colour) of the time periods to move
any images etc will be loaded once the animation is complete

Yes, but the biggest problem is usually with the rendering. If you're
going to move 100 extremely complex movieclips and the framerate is
bad, no tween class will help you make it faster because the
bottleneck will be on rendering and not on the code.

Hi all
I'm going to be doing a zooming timeline (similar to the frankly
stunning one at
http://www.bbc.co.uk/history/british/launch_tl_british.shtml) from
scratch and I was hoping someone would be able to answer a question
for me
if i wanted to do the zoom with the actionscript tween and easing
classes, would they be able to cope with moving 100 or more clips at
once? or would i be better off with a more traditional onEnterFrame /
delete onEnterFrame and some kind of updateScreen routine?
Either way, i'll probably have to reduce the _quality of the movie
while the animation runs to keep it smooth
hope you can help
