Hidden assumption:  this film is playing back on your TV set at the
same speed it was photographed.  (Or is it video?)  In any case, you
need to know the correct frame rate to get an accurate value for t, and
even then you will have some irreducible error in the measurement,
thanks to the discrete time resolution of film and video.

Now, if your government is lying about the Moon's gravity, why should
they tell you the truth about the frame rate on this little video?

I apologize for doing the opposite, but I couldn't resist.
