When using the media processing feature, you usually need to set a series of parameters, which can be combined through a template. This simplifies your operations and allows you to reuse the configured parameters with no need to enter them repeatedly.
For media processing features such as audio/video transcoding, audio/video splicing, video frame capturing, and video-to-animated image conversion, you need to specify a template when creating a job or workflow in CI. The template page provides preset templates, and you can also customize templates based on your business needs.
Preset Templates
The CI system combines common parameters in advance into preset templates, so that you can use them directly. When creating a job or workflow, you can select such a template by the template name.
On the bucket management page, click Job and Workflow > Template Configuration to view templates of different processing types. Click View on the right of a template to view its detailed information.
Note:
Currently, the system provides 15 audio/video transcoding, three video frame capturing, and 18 video-to-animated image conversion preset templates.
You can only view the information of preset templates but cannot edit or delete them.
