Timeline scrubber

I know this can be an old post…but I am not a programmer, I am designer and an animator…

what I want is a timeline scrubber which I put in the main timeline…where I also call the movieclip to play…

the movieclip can be of any size, can have audio or anything, but the scrubber should stay of the constant size for all the movie clips, move along with movieclip and should be draggable meaning that I can drag it forward or back and start the movie clip from that point…any help would be highly appreciated.
