Too much of the video being posted in the MA section is shot in a fashion that makes it very hard to do quality MA. When we have video that is shot this way, often the best we can do is guess because we really can't see what is going on. It is the student that misses out when the video quality is poor.
I have asked Max to post here with a tutorial. He is the best I have seen at shooting video for MA. Before he posts here are some basics:
1. Always shoot from a stationary position. Skiing behind someone may be a nice effect but it makes doing quality MA a chore
2. In general shooting someone from the front is preferable to shooting them from behind.
3. The best video has the skier taking up 50% or more of the screen. This means the videographer can't be a huge distance from the skier.
4. Too high a zoom (anything beyond 10X) will make the video shake the whole time without a tripod (which no one uses to shoot skiing video).
5. The ideal video has the videographer positioned so he/she can capture 5-6 turns from the front and then capture the next 5-6 turns from the back after the skier passes. Pretty much anything that tries to capture much more than 6-8 turns (from front and back) will be of poor quality on the turns where the videographer is furthest away. Remember, 6 turns from both sides is plenty for MA. Most issues reveal themselves in less than 12 turns.
Max can give better specifics on how to accomplish much of this.
If you will post video that follows these guidelines, the quality of the MA will be much better and you will learn much faster!!
