# Rack Zoom (Crash Zoom)

That sudden zoom that screams “something just got real.”

## What it is

A rack zoom (often called a crash zoom) is a sudden change in focal length, rapidly zooming in or out on a subject. It’s usually performed mid-shot for exaggerated impact.

## Why it's important

Crash zooms are bold stylistic choices. It draws instant attention and creates urgency or surprise. It’s a popular technique in action scenes, parody, and energetic edits.

## When/how to use

Use rack zooms sparingly for comedic timing, emphasis, or genre-specific moments. It’s most effective when timed with sound or movement.

## Best Practices

1. **Use sparingly –** Reserve rack zooms for moments of shock, humor, or heightened intensity.
2. **Match genre/style –** Works well in grindhouse, action, or satirical contexts; can feel out of place elsewhere.
3. **Stabilize carefully –** Ensure camera shake doesn’t distract from the intended punch of the zoom.
