Depth of field
A wider opening can isolate your subject. Focus distance matters too. Fixed-distance illustration, not an optical calculation.

Motion blur · 180°
Near 180°: a familiar amount of motion blur. This is a starting guideline, not a requirement. Playback 25 FPS / capture 25 FPS = 1.00× speed. Trail is illustrative.
What these settings change
Shutter • time collecting light
Each frame collects light for 1/50 second. A longer exposure collects more light and more movement.
ISO • output brightness
ISO 400 changes output brightness, not incoming light. With little captured light, noise can become easier to see.
