If you create the looping parts as a separate movieclip that you place on one layer of the timeline, you can have them continuously looping while the text on the main timeline just animates in and the main timeline has a stop() at the end. To create that animating movieclip, copy the frames/layers of the looping stuff, create a new movieclip symbol, select the one keyframe in the empty movieclip and paste the frames in... the layers and frames will fill automatically.
Then you just need to place that movieclip on a layer in the maintimeline and be sure it extends the length of the timeline.
Thanks a lot!!! It worked. I got another question, which I am not sure is possible =/.
the colour I want to overlay is around #88989e On eandms, the flash is fully red, on mine it is not. I've tried the tint function, its not as effective =/
I haven't done it before myself, but one thing you probably need to do is convert your images to black and white rather than color photos. That way you won't have other colors interfering with the desired overlay color.
Another thing you might consider... those images look awfully crisp, meaning I don't think there's an overlay (would tend to subdue the crispness) involved as much as the images were doctored for the color effect. The first one transitioning may be just a mask revealing the red one over a b&w one.
