If you want to watch fighting, Muhammad Ali gives a good level of efficiency in bodily movement.

IMO, a good application video could be anything. If your skill is high, the application video could be of you raking your garden, or doing dishes - could be of you painting your deck or sanding your floor.
A mind without discursive thinking in all of these things will contribute to that conscious clarity that can wash the unconscious bit by bit - but this is really just more of cheap theory I am interpreting from Buddhism admittedly.
Here are some monks sparring around with a young guy who likes to spar. I doubt they get a lot of exposure to sparring around with other stylists, or other fighters, as their focus is on the Buddhas teachings, and not necessarily on sparring.

As to from me - I wouldn't make such videos as my skill is quite low and my focus isn't fighting. If you wanted to be a great fighter though - why not just tell your teacher you want to focus on it. Then learn from him - and if you want to hang out with other stylists, you can test out there to, and elsewhere?
If my own beliefs aren't clear - it is that internal is a component of training, an important component. In fighting, it is needed to ensure there is little to no recovery time from mis-step, or unexpected stepping of the other person. It is further needed to ensure the mind is clear on the conscious level, and if it has been sweeped clean enough, perhaps somewhat on the subconscious reactive level as well. It doesn't give you fighting ability - that has to be trained through fighting whatever way you want.
It gives you fertile soil to plant seeds - if you want a fighting plant, plant some fighting seeds there. It takes away some of the guessing in power generation and mental reactions to 'attackers' and helps us understand our self.
It isn't that you all the sudden obtain "Internal Power" and can defeat everyone - that is just the false image so many people are painting from both imaginary sides of the argument. It is in stages and levels, if you train a little more, you'll get a little more result.
