S3 Ingestion

Frequency provides two different paths to utilize AWS S3 for content ingestion via either a Frequency provided S3 or direct integration with a partner S3.

Frequency S3 Ingestion

Frequency provides a secure method for transferring content into Frequency Studio using Amazon S3 storage. To ensure successful content ingestion, the following assets are supported:

Deliverable

Required

Description

Example

Video asset

Required

The video asset being ingested.

  • Supported file extensions: mp4, avi, mov, mpg, mxf, mkv

  • Minimum 1280x720 resolution

  • 16:9 Aspect Ratio

movie.mp4

Image asset

Required

An image representing your video asset (cannot be a black square).

  • Supported file extensions: jpg, png

  • Minimum 1280x720 resolution

  • 16:9 Aspect Ratio

thumbnail.png

Caption file

Optional

Caption files to accompany video assets.

  • Supported file extensions: srt, vtt, srt, ttml, stl, smi

captions.scc

Cuepoints

Optional

Where ad breaks can be inserted into videos. This value will be in milliseconds.

Metadata file

Required

A .csv file containing required and optional metadata for ingestion. This links your assets and metadata into one item.

Required metadata:

For optional metadata fields, please see the attached manifest, and refer to

Metadata Definitions.

  • GUID

  • Title

  • Description

  • Video File Name + Extension (e.g. video.mp4)

  • Thumbnail File Name + Extension (e.g. thumbnail.jpg

metadata-manifest.csv

Credentials delivery

Frequency will securely deliver the following credentials to allow access to Frequency S3 storage:

  • Access Key ID - Example: AKIARECHFGWRLHEXAMPLE

  • Secret Access Key (Do not share) - Example: arLwJXUtnFEMI/f+/cxv/bPxRfiCYEXAMPLEKEY

  • Path - Example: partner-videos

Keep these credentials private and secure. You can use them with third-party clients like Transmit or Cyberduck for remote access to the provided S3 storage.

Connecting to a client

Input the following information into your S3 client settings:

  1. Address: s3.amazonaws.com

  2. Access Key ID: <provided by Frequency>

  3. Secret Access Key: <provided by Frequency>

  4. Path: <provided by Frequency>

Uploading files
  • All assets (videos, thumbnails, and caption files) must be uploaded to S3 before updating the metadata.csv file.

  • Uploading items after updating the .csv file risks omission from the ingestion package and potential ingestion failures due to missing assets.

  • Use valid file and folder path names in the .csv file for smooth ingestion via S3.

  • File names are case-sensitive, should not contain spaces, and have limited special character support (refer to AWS' guide on Creating Object Key Names

Upload Metadata Manifest File
  • Upload a manifest file in CSV format (e.g., metadata.csv) describing your uploaded content.

  • Ensure the required fields video_file and image_file match file names and have a 16:9 aspect ratio with at least 720p resolution.

  • Refer to file paths as needed (e.g., if "myvideo.mp4" is in the main folder, use that for the video file; if in "videos" subfolder, use "videos/myvideo.mp4").

  • Update this manifest file after confirming successful asset uploads.

  • Avoid spaces or special characters in folder names.

  • Overwrite the file with new information when necessary.

CSV Example

metadata.csv

Live Google Sheet Example

Metadata File Template (metadata.csv) - Google Sheets

File Structure Guidelines
  • Upload your metadata.csv after all assets have been fully uploaded.

  • Avoid spaces in file names.

  • Avoid most special characters (details below).

  • Data with line breaks will not be valid.

  • Ensure correct file paths on assets.

  • File names are case-sensitive.

  • Entry order in metadata.csv affects ingestion order.

Automated Ingestion

Frequency periodically checks the metadata manifest file to detect new videos for ingestion. Successfully ingested videos appear in the MANAGE tool.Overview

File Name Convention

Asset names must adhere to S3's Creating Object Key Names.

The name for a key is a sequence of Unicode characters whose UTF-8 encoding is at most 1,024 bytes long.

Safe characters

Please ensure your file names only use the following safe characters:

Alphanumeric characters

  • 0-9

  • a-z

  • A-Z

Special characters

  • No spaces in file or folder names

  • Forward slash ( / )

  • Exclamation point ( ! )

  • Hyphen ( - )

  • Underscore ( _ )

  • Period ( . ) Exception: Object name key cannot end with a single period (.), or two periods (..)

  • Asterisk ( * )

  • Single quote ( ' )

  • Open parenthesis ( ( )

  • Close parenthesis ( ) )

Partner S3 Ingestion

If you prefer, Frequency can access your Amazon Web Services (AWS) S3 buckets for content ingestion. Here are the steps and requirements for this alternative ingestion method:

Example

Cross Account Bucket Permissions

If you've configured authentication on your S3 files, you will need to grant Frequency's account cross-account bucket permissions. You can find information on how to do this in the AWS documentation on granting cross-account bucket permissions.

Please be aware of S3 bucket naming limitations, as this may impact Frequency's ability to ingest content.

In order to complete this provisioning process, please reach out to support@frequency.com for the Frequency account ID.

{ "Version": "2012-10-17", "Statement": [ { "Sid": "Example permissions", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::<frequency-account-id>:root" }, "Action": [ "s3:GetBucketLocation", "s3:ListBucket", "s3:GetObject" ], "Resource": "arn:aws:s3:::<bucket-name>" "Resource": "arn:aws:s3:::<bucket-name>/*" } ]
}

Video assets

Video assets to be ingested should have the following specifications:

  • Supported file extensions: mp4, mov, mpg, avi

  • Minimum 1280x720 resolution

  • 16:9 Aspect Ratio

movie.mp4

Image assets

Image assets used to represent your video should meet the following requirements:

Supported file extensions: jpg, png

  • Minimum 1280x720 resolution

  • 16:9 Aspect Ratio

thumbnail.jpg

Metadata file

A .csv file containing required and optional metadata for ingestion is necessary. This file is how your assets will be linked into one object. This file must be publicly available but does not necessarily need to be saved in the shared S3 bucket. It can be hosted in Dropbox or Google Sheets.

Required metadata:

  • GUID

  • Title

  • Description

  • Video S3 URL

  • Thumbnail S3 URL

For optional metadata fields, please see the attached manifest, and refer to Metadata Definitions.

Allowing Frequency to Read S3 Bucket Files

Go to the S3 bucket, click on Permissions, and edit the Bucket Policy.
