No, it is not. Let's look what a video training course is. This is a developed and planned in detail 1-day training on any of 350 subjects, which includes:

1. Guide for the trainer with a detailed description of the topic, discussion topics;
2. Role games, slides;
3. Distribution materials for trainees;
4. Video.

And now let's compare this time with the time the trainer has to spare to develop a training course, how many books he has to analyse, how much time it will take to work exercises and programme through?

Compare the cost for inviting an external trainer and cost of the course. In fact these are equivalent services. But you can use video as many times as you want to - having paid only once.
