Jog Wheel, Shuttle Ring
What is jog wheel?
The circle with a dent is the jog wheel. You can stick a finger on it and turn the wheel. Used mostly to move video frame by frame backward/forward.
You can use it to watch movie at slow motion with fine control.
What is shuttle ring?
The outer ring is the shuttle wheel. It has a spring that turns the wheel back to original position if no twisting force is applied. It is used to fast forward/backward video. How fast the video moves depends on how much you twist the wheel.
When your hand leaves the knob, it springs back to the original neutral position.
Jog/Shuttle wheel was popular with the VHS days (popular in 1980s to 1990s). They usually are on the remote of expensive VHS players. Professional video editing hardware always have it, still.
