Creating a Video Transcoding Task

You can select a video transcoding template and create a video transcoding task to transcode video files stored in OBS buckets.

Prerequisites

  • An input video file has been uploaded to an OBS bucket. MPC is used in the same region as the OBS bucket. If the video file has not been uploaded, upload it by referring to Uploading Media Files.
  • MPC has been authorized to access the buckets that store the input file and output file. If MPC has not been authorized, authorize MPC by referring to Authorizing Access to Cloud Resources.
  • If you want to receive the task status updates, configure the event notifications function. For details, see Configuring Event Notifications.
  • If you want to use a custom transcoding template, create a transcoding template first. For details, see Creating a Transcoding Template.

Restrictions

Supported video codecs: H.264, H.265, MPEG-2, MPEG-4, MJPEG, VP6/7/8/9, WMV1/2/3, and ProRes 422. If the input file is not in one of the preceding formats, transcoding will fail.

Procedure

  1. Log in to the MPC console.
  2. In the navigation pane, choose Media Processing > Transcoding.
  3. On the displayed page, click Create Task.

    On the Create Task page, configure video transcoding parameters.

  4. Configure basic parameters, as shown in Figure 1.

    Select the bucket and file name of the source video, and the bucket and output path of the transcoded video.

  5. Select a transcoding template that best fits your needs, as shown in Figure 2.

    Figure 2 Transcoding templates

    A large number of Single Output and Multiple Outputs templates are preset in MPC. System templates are preferred as they contain common parameters such as the definition, bitrate, and resolution. You can choose Global Settings > System Templates to view the parameters of a system template on the MPC console.

    • Audio files cannot be transcoded using a video transcoding template.
    • GIF files can be transcoded only to MP4 files.

  6. Click OK.
  7. View the task status in the task list.

    You can view details about transcoding tasks of the past 60 days.
