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

Video codecs supported are H.264, H.265, MPEG-2, MPEG-4, MJPEG, VP6/7/8/9, WMV1/2/3, and ProRes 422. If an input file is not in one of these formats, transcoding will fail.

Procedure

  1. Log in to the MPC console.
  2. In the navigation pane, choose Media Processing > Transcoding.
  3. Click Create Task.
  4. Configure basic parameters, including the buckets and paths for storing an input file and output file.

  5. Select a transcoding template as required.

    MPC provides a wealth of one-in one-out and one-in multiple-out system templates, which are configured with common parameters such as the definition, bitrate, and resolution. You are advised to use system templates. 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.
    • Video files in GIF format can be transcoded only to MP4 files.
    • If you need a transcoding template that supports adaptive bitrate and image enhancement, submit a service ticket.

  6. Click OK.
  7. View the transcoding task status in the task list. You can view details about transcoding tasks of the past 60 days.

    • If transcoding succeeds, click Output Path in the Output column to switch to the OBS console, where you can view, download, and share the transcoded video file.
    • If transcoding fails, view the failure cause in the Output column for troubleshooting.
