You take the length of the full progressbar and devide that with the number of frames in the movie, to get a "factor".
To make the progressbar follow the movie, tell the progressbar sprite that it's width should be the current frame of the movie, mulitplied with the factor.

Example:
Length (actually width) of progressbar = 300
Number of frames in the movie = 1200
This gives a factor of 0.25

The movie is in frame 40, multiply with 0.25, and you get 10 pixels across for the progressbar.
The movie is in frame 600 (halfways), multiply with 0.25 and you get 150 pixels across for the progressbar, which indeed also is halfways.
