## What this tool does
Convert landscape video to 9:16 without cutting off the subject — content-aware crop window, pay per clip.

## Typical user problems
- Reposting a landscape video to Shorts means manual cropping, and naive center-crop cuts people in half. Reframing tools lock you into $16-24/mo subscriptions. This tool samples frames across the clip, builds a content-energy map and picks the crop window that keeps the action in frame — pay per clip, no subscription.
