Create Job
Description
To create a job, send a POST request to the /2012-09-25/jobs
resource. Jobs
start as soon as you create them.
Note
You can configure Elastic Transcoder to notify you when the status of a job changes, including when Elastic Transcoder starts and finishes processing a job, and when Elastic Transcoder encounters a warning or error condition. For more information, see Create Pipeline.

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 Settings that You Specify When You Create an Elastic Transcoder Job.
In addition, Elastic Transcoder returns the following values.
- (Automatic) Id
-
The identifier that Elastic Transcoder assigned to the job. You use this value to get settings for the job or to delete the job.
- (Automatic) Outputs:Id
-
A sequential counter, starting with 1, that identifies an output among the outputs from the current job. In the
Output
syntax, this value is always1
. - (Automatic) Outputs:Duration
-
Duration of the output file in seconds, rounded up.
- (Automatic) Outputs:Width
-
Width of the output file, in pixels.
- (Automatic) Outputs:Height
-
Height of the output file, in pixels.
- (Automatic) Outputs:Status
-
The status of one output in a job. If you specified only one output for the job,
Outputs:Status
is always the same asJob:Status
. If you specified more than one output:Job:Status
andOutputs:Status
for all of the outputs isSubmitted
until Elastic Transcoder starts to process the first output.When Elastic Transcoder starts to process the first output,
Outputs:Status
for that output andJob:Status
both change toProgressing
. For each output, the value ofOutputs:Status
remainsSubmitted
until Elastic Transcoder starts to process the output.Job:Status
remainsProgressing
until all of the outputs reach a terminal status, eitherComplete
orError
.When all of the outputs reach a terminal status,
Job:Status
changes toComplete
only ifOutputs:Status
for all of the outputs isComplete
. IfOutputs:Status
for one or more outputs isError
, the terminal status forJob:Status
is alsoError
.
The value of
Status
is one of the following:Submitted
,Progressing
,Complete
,Canceled
, orError
. - (Automatic) Outputs:StatusDetail
-
Information that further explains
Outputs:Status
. - (Automatic) Outputs:AppliedColorSpaceConversion
-
If Elastic Transcoder used a preset with a
ColorSpaceConversionMode
to transcode the output file, theAppliedColorSpaceConversion
parameter shows the conversion used. If noColorSpaceConversionMode
was defined in the preset, this parameter will not be included in the job response. - (Automatic) Status
-
If you specified more than one output for the job, the status of the entire job. When Elastic Transcoder starts processing a job, the value of
Job:Status
changes toProgressing
and doesn't change until Elastic Transcoder has finished processing all outputs. When processing is complete,Job:Status
changes either toComplete
or, if any of the outputs failed, toError
.If you specified only one output for the job,
Job:Status
is the same asOutputs:Status
.The value of
Job:Status
is one of the following:Submitted
,Progressing
,Complete
,Canceled
, orError
.
Errors
For information about Elastic Transcoder exceptions and error messages, see Handling Errors in Elastic Transcoder.
Note
If a job fails with an Access Denied
error, we recommend that you run the Test Role
API action
to determine what is causing the error. For more information, see Test Role.
Examples
The following example request creates a job that has two outputs.
