Create Preset

Description

To create a preset, send a POST request to the /2012-09-25/presets resource.

Important

Elastic Transcoder checks the settings that you specify to ensure that they meet Elastic Transcoder requirements and to determine whether they comply with the applicable standard. If your settings are not valid for Elastic Transcoder, Elastic Transcoder returns an HTTP 400 response (ValidationException) and does not create the preset. If the settings are valid for Elastic Transcoder but aren't strictly compliant with the standard, Elastic Transcoder creates the preset and returns a warning message in the response. This helps you determine whether your settings comply with the standard while giving you greater flexibility with respect to the file that Elastic Transcoder produces.

Note

Elastic Transcoder includes several system presets for common output formats. For more information, see PresetId in the topic Create Job.

Response Headers

This operation uses only response headers that are common to most responses. For information about common response headers, see HTTP Responses.

Response Body

When you create a job, Elastic Transcoder returns the values that you specified in the request. For more information, see Request Body.

In addition, Elastic Transcoder returns the following values.

(Automatic) Id

Identifier for the new preset. You use this value to get settings for the preset or to delete it.

(Automatic) Type

Whether the preset is a default preset provided by Elastic Transcoder (System) or a preset that you have defined (Custom).

(Automatic) Warning

When the settings for a preset are not compliant with the standards for the Codec but the settings might produce acceptable output, Elastic Transcoder creates the preset and includes a warning explaining how the preset settings are not compliant.

Errors

For information about Elastic Transcoder exceptions and error messages, see Handling Errors in Elastic Transcoder.

Examples

The following example request creates a preset named DefaultPreset.
