Here's the thing. Say I make a video of a guy shoveling dirt. He could be using convention muscle, convention way of moving, etc. Or the guy could be using internal power. Either way it would look like a video of a guy shoveling dirt. Replace shoveling dirt with a a judo throw, or a shiho-nage or whatever. It doesn't look much different.
But it would look somewhat
different and that should be enough if one were to make a video specifically to illustrate the difference between conventional movement and internal movement.
