Video editing

Video editing combines materials, such as video clips, audio files, and images, on a Timeline to generate a new video file.

API operations

• Submit a video editing task: Call the SubmitMediaProducingJob operation to combine one or more video, audio, image, and subtitle materials into a final product. This operation supports complex Timeline configurations to meet various editing needs.

• Query a video editing task: Call the GetMediaProducingJob operation and pass the JobId to query the status and results.

Timeline configuration

The timeline configuration defines the editing logic. A Timeline describes the arrangement and combination of materials like video, audio, and images over time. A Timeline primarily consists of three types of objects: tracks, materials, and effects. For detailed configuration instructions, see Timeline configurations.

Basic timeline structure

{
  "VideoTracks": [
    {
      "VideoTrackClip": [
        {
          "MediaId": "Asset ID",
          "MediaURL":"The OSS URL of the video track clip"
        }
      ]
    }
  ],
  "AudioTracks": [
    {
      "AudioTrackClip": [
        {
          "MediaId": "Audio asset ID",
          "MediaURL":"The OSS URL of the audio track clip"
        }
      ]
    }
  ]
}

• VideoTracks: Video tracks are used to place video or image materials.

• AudioTracks: Audio tracks are used to place audio materials.

• Clips: The clips within each track, containing the material ID, start time, and duration.

Timeline examples

The tutorials include numerous examples that demonstrate how to use Timeline configurations to achieve various complex video editing requirements. The following are common use cases and configuration examples:

Use an SDK for video editing

Install and configure the IMS server-side SDK for video editing. For more information, see Preparations.
