Jim Schmitz has some promotional weightlifting videos for the Olympics.
Maybe not the best instructional videos (teaching to consciously shrug the shoulders, bar goes around the knees…) but pretty nice slow motion case studies. Demonstrators: Brian Wilhelm and Kari Shimomura.
Snatch
Clean and Jerk
Front & Back Squat
Front & Back Squat works, the other two are blocked in Sweden.
Same in Germany…
