How to resize video

  1. Drop the video.
  2. Pick the height.
  3. Press Resize and download the MP4.

What happens to your file

Every frame is scaled to the height you pick with the width following the aspect ratio (rounded to an even number, as H.264 needs), then the clip is re-encoded as H.264 with AAC sound and written with its index at the front. Sound is untouched.

A clip already at or below the height is re-encoded at its own size — nothing is ever enlarged, because an enlarged video is only a blurry big one.

Questions

Does resizing make the file smaller?

Usually by a lot: half the height is a quarter of the pixels. For the smallest file at a given size, see Compress video, which also picks a bitrate.

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.resize",
    "options": {
      "height": 720
    }
  }'

The same operation, video.resize — Down to 480, 720 or 1080 lines; never enlarged past sense. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
