I read this thread with some bemusement.
We are quite proud of both Internal Force Dynamics 1 & Internal Force Dynamics 2. A great many hours was spent both in filming and post production. Vol. 1 uses picture in picture and very slow motion technology to accurately demonstrate wave force, something that as was pointed out, was not explained to me for many years when I studied. Vol. 2 uses animation overlay to depict ground path and both the load and release phase, again in slow motion. Something that again, took me years to learn.
This is my new direction in video.. bringing things out that are real. I see many people today, even teachers, that do not understand so much.
At the end of the day, I am trying to both archive and help to raise the level of awarness in the internal arts, something that is very dear to me.
Btw, we DO have sample clips for each video which are an amalgum of actual scenes from the video in question. You can always look at those and try to determine if the video is for you or not. That's sort of the idea behind the clips?
