This page explains how to generate a spritesheet that contains frames from a video you transcode. These reduced-sized frames, also known as thumbnails, are useful for organizing and previewing content. To generate the spritesheet, use the [`spriteSheets`](https://docs.cloud.google.com/transcoder/docs/reference/rest/v1/JobConfig) array in the `JobConfig` template. You have two options for generating the spritesheet: - [Generate a set number of thumbnail images](https://docs.cloud.google.com/transcoder/docs/how-to/generate-spritesheet#generate_set_number_of_images) distributed evenly across the input video timeline. - [Generate a thumbnail image periodically](https://docs.cloud.google.com/transcoder/docs/how-to/generate-spritesheet#generate_image_periodically), that is, every *n* seconds, across the input video timeline. ## Generate a set number of thumbnail images The following configuration generates a 10x10 spritesheet of large images and a 10x10 spritesheet of small images, each with 100 thumbnails. Note that spritesheets require at least one `VideoStream` in the job configuration. You can add this configuration to a [job template](https://docs.cloud.google.com/transcoder/docs/how-to/job-templates) or include it in an [ad-hoc job configuration](https://docs.cloud.google.com/transcoder/docs/how-to/jobs#create_jobs_ad_hoc): ### REST Before using any of the request data, make the following replacements: - `PROJECT_ID`: Your Google Cloud project ID listed in the [IAM Settings](https://console.cloud.google.com/iam-admin/settings/project). - `LOCATION`: The location where your job will run. Use one of the [supported regions](https://docs.cloud.google.com/transcoder/docs/locations). Show locations - `us-central1` - `us-west1` - `us-west2` - `us-east1` - `us-east4` - `southamerica-east1` - `northamerica-northeast1` - `asia-east1` - `asia-northeast1` - `asia-northeast3` - `asia-south1` - `asia-southeast1` - `australia-southeast1` - `europe-west1` - `europe-west2` - `europe-west4` - `me-west1` - `me-central1` - `me-central2` - `STORAGE_BUCKET_NAME`: The name of the Cloud Storage bucket you created. - `STORAGE_INPUT_VIDEO`: The name of the video in your Cloud Storage bucket that you are transcoding, such as `my-vid.mp4`. This field should take into account any folders that you created in the bucket (for example, `input/my-vid.mp4`). - `STORAGE_OUTPUT_FOLDER`: The Cloud Storage folder name where you want to save the encoded video outputs. **Note:** You don't need to create the output folder object before creating the job. When processing the job, the Transcoder API automatically prepends the folder name you specify as part of the names of the objects saved to Cloud Storage. To send your request, expand one of these options: #### curl (Linux, macOS, or Cloud Shell) > [!NOTE] > **Note:** The following command assumes that you have logged in to the `gcloud` CLI with your user account by running [`gcloud init`](https://docs.cloud.google.com/sdk/gcloud/reference/init) or [`gcloud auth login`](https://docs.cloud.google.com/sdk/gcloud/reference/auth/login) , or by using [Cloud Shell](https://docs.cloud.google.com/shell/docs), which automatically logs you into the `gcloud` CLI . You can check the currently active account by running [`gcloud auth list`](https://docs.cloud.google.com/sdk/gcloud/reference/auth/list). Save the request body in a file named `request.json`. Run the following command in the terminal to create or overwrite this file in the current directory: ``` cat > request.json << 'EOF' { "config": { "inputs": [ { "key": "input0", "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO" } ], "elementaryStreams": [ { "key": "video-stream0", "videoStream": { "h264": { "heightPixels": 360, "widthPixels": 640, "bitrateBps": 550000, "frameRate": 60 } } }, { "key": "audio-stream0", "audioStream": { "codec": "aac", "bitrateBps": 64000 } } ], "muxStreams": [ { "key": "sd", "container": "mp4", "elementaryStreams": [ "video-stream0", "audio-stream0" ] } ], "output": { "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/" }, "spriteSheets": [ { "filePrefix": "small-sprite-sheet", "spriteHeightPixels": 32, "spriteWidthPixels": 64, "columnCount": 10, "rowCount": 10, "totalCount": 100 }, { "filePrefix": "large-sprite-sheet", "spriteHeightPixels": 72, "spriteWidthPixels": 128, "columnCount": 10, "rowCount": 10, "totalCount": 100 } ] } } EOF ``` Then execute the following command to send your REST request: ``` curl -X POST \ -H "Authorization: Bearer $(gcloud auth print-access-token)" \ -H "Content-Type: application/json; charset=utf-8" \ -d @request.json \ "https://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobs" ``` #### PowerShell (Windows) > [!NOTE] > **Note:** The following command assumes that you have logged in to the `gcloud` CLI with your user account by running [`gcloud init`](https://docs.cloud.google.com/sdk/gcloud/reference/init) or [`gcloud auth login`](https://docs.cloud.google.com/sdk/gcloud/reference/auth/login) .

Create a `request.json` file that defines the job fields. Make the following replacements for the [`gcloud`](https://docs.cloud.google.com/sdk/gcloud/reference/transcoder/jobs/create) command: - STORAGE_BUCKET_NAME: The name of the Cloud Storage bucket you created. - STORAGE_INPUT_VIDEO: The name of the video in your Cloud Storage bucket that you are transcoding, such as `my-vid.mp4`. This field should take into account any folders that you created in the bucket (for example, `input/my-vid.mp4`). - LOCATION: The location where your job will run. Use a location from the following list. Show locations - `us-central1` - `us-west1` - `us-west2` - `us-east1` - `us-east4` - `southamerica-east1` - `northamerica-northeast1` - `asia-east1` - `asia-northeast1` - `asia-northeast3` - `asia-south1` - `asia-southeast1` - `australia-southeast1` - `europe-west1` - `europe-west2` - `europe-west4` - `me-west1` - `me-central1` - `me-central2` - STORAGE_OUTPUT_FOLDER: The Cloud Storage folder name where you want to save the encoded video outputs. **Note:** You don't need to create the output folder object before creating the job. When processing the job, the Transcoder API automatically prepends the folder name you specify as part of the names of the objects saved to Cloud Storage. ```bash { "config": { "inputs": [ { "key": "input0", "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO" } ], "elementaryStreams": [ { "key": "video-stream0", "videoStream": { "h264": { "heightPixels": 360, "widthPixels": 640, "bitrateBps": 550000, "frameRate": 60 } } }, { "key": "audio-stream0", "audioStream": { "codec": "aac", "bitrateBps": 64000 } } ], "muxStreams": [ { "key": "sd", "container": "mp4", "elementaryStreams": [ "video-stream0", "audio-stream0" ] } ], "output": { "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/" }, "spriteSheets": [ { "filePrefix": "small-sprite-sheet", "spriteHeightPixels": 32, "spriteWidthPixels": 64, "columnCount": 10, "rowCount": 10, "totalCount": 100 }, { "filePrefix": "large-sprite-sheet", "spriteHeightPixels": 72, "spriteWidthPixels": 128, "columnCount": 10, "rowCount": 10, "totalCount": 100 } ] } } ``` 2. Run the following command: ```bash gcloud transcoder jobs create --location=LOCATION --file="request.json" ``` You should see a response similar to the following: ``` { "name": "projects/PROJECT_NUMBER/locations/LOCATION/jobs/JOB_ID", "config": { ... }, "state": "PENDING", "createTime": CREATE_TIME, "ttlAfterCompletionDays": 30 } ``` ### C# Before trying this sample, follow the C# setup instructions in the [Transcoder API quickstart using client libraries](https://docs.cloud.google.com/transcoder/docs/quickstart-client-libraries).

Each spritesheet contains thumbnails that were generated every 7 seconds from the input video. Note that spritesheets require at least one `VideoStream` in the job configuration. You can add this configuration to a [job template](https://docs.cloud.google.com/transcoder/docs/how-to/job-templates) or include it in an [ad-hoc job configuration](https://docs.cloud.google.com/transcoder/docs/how-to/jobs#create_jobs_ad_hoc): ### REST Before using any of the request data, make the following replacements: - `PROJECT_ID`: Your Google Cloud project ID listed in the [IAM Settings](https://console.cloud.google.com/iam-admin/settings/project). - `LOCATION`: The location where your job will run. Use one of the [supported regions](https://docs.cloud.google.com/transcoder/docs/locations). Show locations - `us-central1` - `us-west1` - `us-west2` - `us-east1` - `us-east4` - `southamerica-east1` - `northamerica-northeast1` - `asia-east1` - `asia-northeast1` - `asia-northeast3` - `asia-south1` - `asia-southeast1` - `australia-southeast1` - `europe-west1` - `europe-west2` - `europe-west4` - `me-west1` - `me-central1` - `me-central2` - `STORAGE_BUCKET_NAME`: The name of the Cloud Storage bucket you created. - `STORAGE_INPUT_VIDEO`: The name of the video in your Cloud Storage bucket that you are transcoding, such as `my-vid.mp4`. This field should take into account any folders that you created in the bucket (for example, `input/my-vid.mp4`). - `STORAGE_OUTPUT_FOLDER`: The Cloud Storage folder name where you want to save the encoded video outputs. **Note:** You don't need to create the output folder object before creating the job. When processing the job, the Transcoder API automatically prepends the folder name you specify as part of the names of the objects saved to Cloud Storage.

Run the following command in the terminal to create or overwrite this file in the current directory: ``` @' { "config": { "inputs": [ { "key": "input0", "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO" } ], "elementaryStreams": [ { "key": "video-stream0", "videoStream": { "h264": { "heightPixels": 360, "widthPixels": 640, "bitrateBps": 550000, "frameRate": 60 } } }, { "key": "audio-stream0", "audioStream": { "codec": "aac", "bitrateBps": 64000 } } ], "muxStreams": [ { "key": "sd", "container": "mp4", "elementaryStreams": [ "video-stream0", "audio-stream0" ] } ], "output": { "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/" }, "spriteSheets": [ { "filePrefix": "small-sprite-sheet", "spriteHeightPixels": 32, "spriteWidthPixels": 64, "interval": "7s" }, { "filePrefix": "large-sprite-sheet", "spriteHeightPixels": 72, "spriteWidthPixels": 128, "interval": "7s" } ] } } '@ | Out-File -FilePath request.json -Encoding utf8 ``` Then execute the following command to send your REST request: ``` $cred = gcloud auth print-access-token $headers = @{ "Authorization" = "Bearer $cred" } Invoke-WebRequest ` -Method POST ` -Headers $headers ` -ContentType: "application/json; charset=utf-8" ` -InFile request.json ` -Uri "https://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobs" | Select-Object -Expand Content ``` You should receive a JSON response similar to the following: ``` { "name": "projects/PROJECT_NUMBER/locations/LOCATION/jobs/JOB_ID", "config": { ... }, "state": "PENDING", "createTime": CREATE_TIME, "ttlAfterCompletionDays": 30 } ``` ### gcloud 1. Create a `request.json` file that defines the job fields. Make the following replacements for the [`gcloud`](https://docs.cloud.google.com/sdk/gcloud/reference/transcoder/jobs/create) command: - STORAGE_BUCKET_NAME: The name of the Cloud Storage bucket you created. - STORAGE_INPUT_VIDEO: The name of the video in your Cloud Storage bucket that you are transcoding, such as `my-vid.mp4`. This field should take into account any folders that you created in the bucket (for example, `input/my-vid.mp4`). - LOCATION: The location where your job will run. Use a location from the following list. Show locations - `us-central1` - `us-west1` - `us-west2` - `us-east1` - `us-east4` - `southamerica-east1` - `northamerica-northeast1` - `asia-east1` - `asia-northeast1` - `asia-northeast3` - `asia-south1` - `asia-southeast1` - `australia-southeast1` - `europe-west1` - `europe-west2` - `europe-west4` - `me-west1` - `me-central1` - `me-central2` - STORAGE_OUTPUT_FOLDER: The Cloud Storage folder name where you want to save the encoded video outputs. **Note:** You don't need to create the output folder object before creating the job. When processing the job, the Transcoder API automatically prepends the folder name you specify as part of the names of the objects saved to Cloud Storage. ```bash { "config": { "inputs": [ { "key": "input0", "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO" } ], "elementaryStreams": [ { "key": "video-stream0", "videoStream": { "h264": { "heightPixels": 360, "widthPixels": 640, "bitrateBps": 550000, "frameRate": 60 } } }, { "key": "audio-stream0", "audioStream": { "codec": "aac", "bitrateBps": 64000 } } ], "muxStreams": [ { "key": "sd", "container": "mp4", "elementaryStreams": [ "video-stream0", "audio-stream0" ] } ], "output": { "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/" }, "spriteSheets": [ { "filePrefix": "small-sprite-sheet", "spriteHeightPixels": 32, "spriteWidthPixels": 64, "interval": "7s" }, { "filePrefix": "large-sprite-sheet", "spriteHeightPixels": 72, "spriteWidthPixels": 128, "interval": "7s" } ] } } ``` 2. Run the following command: ```bash gcloud transcoder jobs create --location=LOCATION --file="request.json" ``` You should see a response similar to the following: ``` { "name": "projects/PROJECT_NUMBER/locations/LOCATION/jobs/JOB_ID", "config": { ... }, "state": "PENDING", "createTime": CREATE_TIME, "ttlAfterCompletionDays": 30 } ``` ### C# Before trying this sample, follow the C# setup instructions in the [Transcoder API quickstart using client libraries](https://docs.cloud.google.com/transcoder/docs/quickstart-client-libraries).
