How to trim a video with an API

Cutting a clip to the interesting part is the most common edit there is. By hand it means getting the seek and duration flags right so you do not re-encode or land on the wrong keyframe. Here is the one-call version.

Try trim videoRead the docs

The manual FFmpeg way

Flag order matters: -ss before -i seeks fast but can land on a keyframe, while -c copy avoids a re-encode. A typed API takes start and end seconds and handles the rest.

ffmpeg -ss 2.5 -to 17 -i input.mp4 -c copy trimmed.mp4

Do it with one API call

  1. 1

    Provide the source video

    Give a public URL or upload the file and use the returned media URL as the input named "main".

  2. 2

    Call the trim tool

    Set start in seconds, and optionally end. Omit end to trim to the finish.

  3. 3

    Download the clip

    Poll the job and download the trimmed MP4 from the signed output URL.

REST
curl https://kinopipe.com/api/v1/tools/trim-video \
  -H "Authorization: Bearer kp_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "inputs": [ { "id": "main", "url": "https://example.com/input.mp4" } ],
    "options": { "start": 2.5, "end": 17 }
  }'
Or just ask your agent
Connect the KinoPipe MCP server and say it in plain language:

“Trim input.mp4 to the section between 2.5 and 17 seconds.”

FAQ

Yes. Both are seconds from the start of the video. Leave out end to trim all the way to the finish.

KinoPipe cuts to your range and returns a clean MP4, so the clip plays correctly from the first frame.
