This link has many of the top tour pros swing in super slow motion (320 or more frames per second).

The great thing about super slow motion is it allows you to see different pivots, takeaways, loading and releases.

At 30 frames or even 60 frames per second many of these swings would look similar.

With the super slow motion (320 or more frames per second) many look different.
