How to crop video

  1. Sign in — 500 free credits a month.
  2. Drop the video and pick the box by eye.
  3. 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 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.
