## What this tool does
Turn a whole video into one 4×5 frame grid — review footage, build storyboard previews.

## Typical user problems
- Reviewing an hour of footage means scrubbing back and forth. A contact sheet spreads evenly-spaced frames across a single image so the whole video can be scanned at a glance — editors call it a filmstrip, stock sites call it a preview grid.
