# Recognizing celebrities in a stored video
<a name="celebrities-video-sqs"></a>

Amazon Rekognition Video celebrity recognition in stored videos is an asynchronous operation. To recognize celebrities in a stored video, use [StartCelebrityRecognition](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_StartCelebrityRecognition.html) to start video analysis. Amazon Rekognition Video publishes the completion status of the video analysis to an Amazon Simple Notification Service topic. If the video analysis is succesful, call [GetCelebrityRecognition](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_GetCelebrityRecognition.html). to get the analysis results. For more information about starting video analysis and getting the results, see [Calling Amazon Rekognition Video operations](api-video.md). 

This procedure expands on the code in [Analyzing a video stored in an Amazon S3 bucket with Java or Python (SDK)](video-analyzing-with-sqs.md), which uses an Amazon SQS queue to get the completion status of a video analysis request. To run this procedure, you need a video file that contains one or more celebrity faces.

**To detect celebrities in a video stored in an Amazon S3 bucket (SDK)**

1. Perform [Analyzing a video stored in an Amazon S3 bucket with Java or Python (SDK)](video-analyzing-with-sqs.md).

1. Add the following code to the class `VideoDetect` that you created in step 1.

#### [ Node.JS ]

   In the following Node.Js code example, replace the value of `amzn-s3-demo-bucket` with the name of the S3 bucket containing your video and the value of `videoName` with the name of the video file. You'll also need to replace the value of `roleArn` with the Arn associated with your IAM service role. Finally, replace the value of `region` with the name of the operating region associated with your account. Replace the value of `profile_name` in the line that creates the Rekognition session with the name of your developer profile.

#### [ CLI ]

   Run the following AWS CLI command to start detecting celebrities in a video.

   ```
   aws rekognition start-celebrity-recognition --video "{"S3Object":{"Bucket":"amzn-s3-demo-bucket","Name":"video-name"}}" \
   --notification-channel "{"SNSTopicArn":"topic-arn","RoleArn":"role-arn"}" \
   --region region-name --profile profile-name
   ```

   Update the following values:
   + Change `amzn-s3-demo-bucket` and `video-name` to the Amazon S3 bucket name and file name that you specified in step 2.
   + Change `region-name` to the AWS region that you're using.
   + Replace the value of `profile-name` with the name of your developer profile.
   + Change `topic-ARN` to the ARN of the Amazon SNS topic you created in step 3 of [Configuring Amazon Rekognition Video](api-video-roles.md).
   + Change `role-ARN` to the ARN of the IAM service role you created in step 7 of [Configuring Amazon Rekognition Video](api-video-roles.md).

   If you are accessing the CLI on a Windows device, use double quotes instead of single quotes and escape the inner double quotes by backslash (i.e. \\) to address any parser errors you may encounter. For an example, see below: 

   ```
   aws rekognition start-celebrity-recognition --video "{\"S3Object\":{\"Bucket\":\"amzn-s3-demo-bucket\",\"Name\":\"video-name\"}}" \
   --notification-channel "{\"SNSTopicArn\":\"topic-arn\",\"RoleArn\":\"role-arn\"}" \
   --region region-name --profile profile-name
   ```

   After running the proceeding code example, copy down the returned `jobID` and provide it to the following `GetCelebrityRecognition` command below to get your results, replacing `job-id-number` with the `jobID` you previously received: 

   ```
   aws rekognition get-celebrity-recognition --job-id job-id-number --profile profile-name                               
   ```

------
**Note**  
If you've already run a video example other than [Analyzing a video stored in an Amazon S3 bucket with Java or Python (SDK)](video-analyzing-with-sqs.md), the code to replace might be different.

1. Run the code. Information about the celebrities recognized in the video is shown.

## GetCelebrityRecognition operation response
<a name="getcelebrityrecognition-operation-output"></a>

The following is an example JSON response. The response includes the following:
+ **Recognized celebrities** – `Celebrities` is an array of celebrities and the times that they are recognized in a video. A [CelebrityRecognition](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_CelebrityRecognition.html) object exists for each time the celebrity is recognized in the video. Each `CelebrityRecognition` contains information about a recognized celebrity ([CelebrityDetail](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_CelebrityDetail.html)) and the time (`Timestamp`) the celebrity was recognized in the video. `Timestamp` is measured in milliseconds from the start of the video. 
+ **CelebrityDetail** – Contains information about a recognized celebrity. It includes the celebrity name (`Name`), identifier (`ID`), the celebrity's known gender(`KnownGender`), and a list of URLs pointing to related content (`Urls`). It also includes the confidence level that Amazon Rekognition Video has in the accuracy of the recognition, and details about the celebrity's face, [FaceDetail](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_FaceDetail.html). If you need to get the related content later, you can use `ID` with [getCelebrityInfo](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_GetCelebrityInfo.html). 
+ **VideoMetadata** – Information about the video that was analyzed.
