Crop Video - Center a subject

Dynamic Crop is an intuitive video editor. It's designed to keep a moving object in video centered over time (that is, to achieve the "motion track" effect).

Use cases:
- Keep a moving project centered;
- motion-track a target;
- Crop a horizontal video into a vertical video for social media.

How to use:
1. Import any video from iPhone camera roll to the app.
2. Gradually advance the timeline at the bottom, and simply move the targeted object to the center over time.
3. Preview the edited video, and export it to camera roll.
