Prompting Movement: Motion Blur and Frozen Action - Nano Banana 2

The single most useful thing in a movement prompt is the split between sharp and smeared. Blur applied to everything looks like a mistake; blur applied selectively looks like speed. So write the division out: a cyclist sharp against a streaked background, or a still crowd with one blurred figure walking through it, or a sharp face with hands smeared mid-gesture.

Left unsaid, the model will usually blur the whole frame or none of it. Named, the contrast does the work — the eye reads the sharp thing as the subject and the smeared thing as evidence that time passed.

Long exposure means the camera stayed still while the world moved through it. Water turns to mist, headlights become continuous ribbons, crowds dissolve into transparent ghosts, and anything genuinely static stays razor sharp. It reads as time accumulating rather than as speed, which is a different feeling entirely and often the one people actually want.

Frozen action is the opposite extreme: no blur anywhere, movement implied purely by what the bodies and objects are doing. Water suspended in separate droplets, a dancer at the top of a leap, dust and debris hanging in the air, hair lifted away from the head. Here you carry the whole burden in the description of the pose, because there is no blur to help you.
