They are made, but where you get them from is another question. The company I employed to train and test my employees used video as part of the teaching, I suppose you could try phoning one or two training companies and ask.
I have my license on counterbalance and reach fork lift trucks. The company brought in a training firm. It was all hands on, they didn't use any videos. TBH I think personally videos don't really help unless you want to emphasise accidents. Not the hardest thing to pass in the world
