Create Custom Enhancement Templates

Note:
Enhancement functions are implemented based on transcoding; enhancement parameters are overlaid on top of the transcoding process. When using enhancement features, both transcoding and enhancement parameters must be configured simultaneously. It is recommended to use them in conjunction with Top Speed Codec (TESC).
Configure enhancement parameters in transcoding templates: You can create and manage custom transcoding templates via the console (refer to Template Settings) or by calling Server-side APIs.
Configure enhancement parameters in adaptive bitrate templates: You can create and manage custom transcoding templates via the console (refer to Template Settings) or by calling Server-side APIs.
Configure enhancement templates in workflows: You can create and manage workflow templates via the console (refer to Template Settings) or by calling Server-side APIs.

Initiating a Task

There are five ways to initiate a transcoding task, namely, directly initiating through server API, directly initiating through the console, and specifying a task upon upload. For more information, please see Video Processing Task System for video processing.
Methods of initiating transcoding tasks:
Call the server API ProcessMedia to initiate a task: specify the template ID in the MediaProcessTask.TranscodeTaskSet parameter in the request.
Initiate a task on a video through the console: add a task flow in the console, set the specifications of transcoding output in it, and use it to initiate video processing.
Specify a task upon upload from server: add a task flow in the console, set the specifications of transcoding output in it, and specify it as the procedure parameter in the ApplyUpload API.
Specify a task upon upload from client: add a task flow in the console, set the specifications of transcoding output in it, and specify it as the procedure parameter in the signature for upload from client.
Upload through console: add a task flow in the console, set the specifications of transcoding output in it, upload a video through the console, select Process Video During Upload, and specify to execute this task flow upon video upload completion.

Getting the Result

After initiating a transcoding task, you can wait for result notification asynchronously or perform task query synchronously to get the task execution result. Below is an example of getting the result notification in normal callback (the fields with null value are omitted):
