How to crop video

Sign in — 500 free credits a month.
Drop the video and pick the box by eye.
Run Crop and download the MP4.

What happens to your file

A still from half a second in is shown in your browser and the box you draw is in the clip’s own pixels. Every frame is cut to that rectangle (rounded to even numbers, as H.264 needs) and the clip is re-encoded as H.264 with its sound as AAC, index at the front. A box outside the frame is pulled inside; smaller than 16 × 16 is refused.

Where the browser cannot play the clip, the box is typed as four numbers; the report shows the rectangle actually cut.

Questions

Can I crop to 9:16 for Reels or TikTok?

Yes — draw a tall box; the numbers under it show its size. The result is exactly that box, so pick a width and height in the 9:16 ratio (say 608 × 1080).

Do it once, not on every form

Fixing a file here means downloading it and going back to the form. The Fylane extension does this work inside the form instead, on the file you already have.

And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.

Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.

Filmed from the extension: three upload fields on a job application, filled from one tap.

Add to Chrome — free What it does

Do this in code

curl -X POST https://api.fylane.dev/v1/jobs \
  -H "Authorization: Bearer $FYLANE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file_id": "<file id>",
    "operation": "video.crop",
    "options": {}
  }'

The same operation, video.crop — A rectangle cut out of every frame, in the frame’s own pixels — clamped, evened for H.264, sixteen pixels a side at least. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
