Produces a video from one or more mezzanine files. You can directly submit mezzanine files by specifying the Timeline parameter. Alternatively, you can submit mezzanine files after you create an online editing project.
Operation Description
- This operation returns only the submission result of a video production task. When the submission result is returned, video production may still be in progress. After a video production task is submitted, the task is queued in the background for asynchronous processing.
- The mezzanine files that are referenced in the timeline of an online editing project can be materials from media assets or videos in the media library.
- Videos are produced based on the ProjectId and Timeline parameters. Take note of the following items when you specify the parameters:
- You must specify at least one of the ProjectId and Timeline parameters. Otherwise, video production fails.
- If you specify only the Timeline parameter, the system automatically creates an online editing project with the specified timeline. Then, the system obtains the mezzanine files that are referenced in the timeline and produces a video from the mezzanine files.
- If you specify only the ProjectId parameter, the system obtains the latest timeline of the specified project and produces a video based on the timeline.
- If you specify both the ProjectId and Timeline parameters, the system produces a video based on the specified timeline and updates the timeline and mezzanine files for the specified online editing project. If you specify other parameters, the system also updates related settings for the online editing project.
- You can apply effects to the video to be produced. For more information, see Special effects.
