You first need to identify your input.

Code:

xxxSource("file")
Assume?ff() # choose TTF or BFF
Bob()

Step thru the Bobbed fields looking for the pattern of how moving parts are rendered. If the original was 24 fps film then you should be able to decern how it has become intertwined with video field structure. If the motion steps 2 forwards then 1 backward then use the other TFF/BFF.

E.g. If it is simple 3-2 pulldown from the dumb bob you will see Frame1, dup1, dup1, Frame2, dup2, Frame3, dup3, dup3, Frame4, Dup4, Frame5, ...

Or if field blending has occured Frame1, dup1, blend12, Frame2, Frame3, blend34, Frame4, ....

Once you have your pattern then you can start reseaching how to recover the original frames.
