How to center-crop a video for a vertical or square post

  1. Inspect the center

    Look at where your subject sits in the widest shot of the source.

  2. Choose the frame

    Select 9:16 for a portrait cut or 1:1 for a square version.

  3. Review the MP4

    Play the opening and the widest action to check faces, labels and captions at the edges.

Reframe a wide master for a smaller screen

The crop keeps the center and trims the edges. A centered subject makes the difference between a clean cut and a missing detail.

Cut a portrait product shot

Put a centered bottle or package into a tall composition for a phone-first post.

Make a square feed version

Keep a centered speaker in the frame while trimming empty space on either side.

Check a side-by-side demo

If one half disappears in the crop, return to the original edit and recompose it before export.

Leave space for new captions

Crop first, then put subtitle text inside the final frame.

Vertical video cropper FAQ

Will the crop follow a person walking across the shot?

The crop stays centred. Check both ends of the clip for hands, faces and products near the edges. Pick the square frame when a narrow portrait crop cuts off an important detail.

What happens to wide text along the bottom of the frame?

Anything outside the crop disappears, including burned-in captions. If you have a separate SRT, crop the video first and burn the captions into the new frame afterward.

What size is the exported frame?

The portrait output is 1080 × 1920 pixels; square is 1080 × 1080.

Will the tool add bars instead of cropping?

No. It fills the output frame by cropping the source to the chosen ratio.

Can I make a square cut for the feed instead?

Yes. Choose 1:1 in the Frame control. Choose 9:16 for the tall version and export each separately from the source.

Why is a face near the edge missing in my export?

The tool takes a centred crop. A subject near the edge of a wide shot may sit outside it. Use a shot with the subject nearer the centre or reframe manually in an editor.

Do I need a soundtrack to make a vertical crop?

No. A silent clip can be cropped. If the source has audio, the MP4 export includes sound.
