Are you sure you should do videos analysis during training?
A little disclaimer, I'm a video analysis expert in figure skating. This article may very well apply to other sports too. I’m often asked if coaches should be doing video analysis during training.
In my opinion, coaches cannot do video analysis during ice training. First, the session must be dynamic not to get the skater freezing. Second, to do video analysis, you must have a reference point. A model.
Because, typically, when you do an analysis, you must collect information/data. With this global picture, you can understand why it is not working. The next step is to define which data is essential to improve or change.
Only then can you think about what and the how. What to change or improve and how to achieve this—the how requests coaching skills and experience.
That's why I think there is confusion in people's minds between doing video analysis and using video during the training.
What most coaches do is a skating course with video support. They film and do instant video feedback with a smartphone or a tablet, using apps dedicated to this with slow motion and drawing features.
