Videos can do a lot of damage
Well, my position about this is contradictory.
I think that Videos are a very valuable tool for research. Also think that if you are going to train with a teacher who lives away from your town, you could benefit from training with the videos first and during your relationship.
But...some people have became "kung fu teachers" just by learning some videos. These are the bad news about this.
So what can we do?
Some teachers edit videos with forms cutting some movements so the guys cannot learn them properly. Others make the mistake to edit "all the style" so many persons just buy the videos and in a while create a school.
Videos are a tool. If you use them properly they are wonderfull. If you dont, just the opposite.
My teacher doesn't like videos very much. I have no authorization to edit (for example) choy li fat videos with complete forms. I think it is a wise decition.
Kindest regards

PD about "learning from videos" it is a reasonable good tool if you plan to go to the teacher some day to make corrections.
