      Feature Description

      This API is used to create a top speed codec transcoding template.

      API Explorer is recommended.
      Click to debug
      Tencent Cloud API Explorer provides various capabilities such as online call, signature verification, SDK code generation, and quick API search. You can also use it to query the request and response of each API call as well as generate sample code for calls.
