Hi, If I remember correctly, Baldwin also has such a film. I think they had high speed film of an upright and grand note being played. Now from what I remember, it's not the relationship between string and hammer that impressed me the most, but the impressive flagpoling, twisting and movement that the hammer shanks went through while getting up to the string. At that time, this was so impressive that it really made me aware of the importance of center pinning before good tone regulation can be done.
