creatives ideas for documentary photo show with video

Hello all
just looking for some feedback on the end of a vid Im doing ...
running out of time for creating 3d and motion effects....getting towards the end and time duration
of the video is getting tight....
whats a good way or some techniques to keep some small video clips and photo album type
inserts to stay ,,,well....exciting....moving forward...but still keep the timeline short?
Thanks for any help and thanks for all the help I have been given ...I will post the link
to the video when done!

Ended up using picture in picture and a 3D image fly through...works nicely to add extra material without adding time to the video
