Amazon Elastic Transcoder

Traditionally, transcoding has been complex for customers in three significant ways. First, customers need to buy and manage transcoding software, which can be expensive and challenging to maintain and configure. Second, producing transcoded output for different kinds of devices often involves trial and error to find the right transcoding setting that play properly and look good to the end user. This trial and error process wastes compute resources. Third, traditional encoding solutions don’t scale up and down with customers’ business needs. Instead, with traditional solutions, customers need to guess how much capacity to provision ahead of time, which inevitably means either wasted money (if they provision too much and leave capacity underutilized) or delay to their business (if they provision too little and need to wait to run their encoding jobs).

With Amazon Elastic Transcoder, developers simply use the web-based console or APIs to create a transcoding job that specifies an input file, the transcoding setting, and the output file. This eliminates these three complexities. First, there is no need to buy, configure or manage underlying transcoding software. Second, Amazon Elastic Transcoder has pre-defined presets for various devices that remove the need to find the right settings for different devices through trial and error. The system also supports custom presets which let customers tune output to specific transcode requirements such as a unique size or bit rate needs. Finally, Amazon Elastic Transcoder automatically scales up and down to handle customers’ workloads, eliminating wasted capacity and minimizing time spent waiting for jobs to complete. It also enables customers to process multiple files in parallel and organize their transcoding workflow using a feature called transcoding pipelines. With Amazon Elastic Transcoder’s pipelines feature, customers set up pipelines for these various scenarios and ensure that their files are transcoded when and how they want, thus allowing them to seamlessly scale for spiky workloads efficiently. For example, a news organization may want to have a “high priority” transcoding pipeline for breaking news stories, or a User-Generated Content website may want to have separate pipelines for low, medium, and high resolution outputs to target different devices.

Amazon Elastic Transcoder is built using the scalability and flexibility of other Amazon Web Services. It runs your transcoding jobs using the Amazon Elastic Compute Cloud (Amazon EC2). Amazon EC2’s scale allows you to complete large transcoding jobs quickly and reliably. Amazon Elastic Transcoder is built to work with content you store in Amazon Simple Storage Service (Amazon S3), so you have durable and cost effective storage for huge libraries, or small ones. You can even get notified about the status of your transcoding jobs via Amazon Simple Notification Service (Amazon SNS).

Amazon Elastic Transcoder features an AWS Management Console and service APIs so you can integrate transcoding into your own applications and services.

To use Amazon Elastic Transcoder, you:

• Create a transcoding pipeline that specifies the input Amazon S3 bucket, the output Amazon S3 bucket, and an AWS Identity and Access Management (IAM) role that is used by the Transcoder to access your files.

• Create a transcoding job by specifying the input file, output file, and transcoding preset to use (you can choose from a set of pre-defined transcoding presets – for example 720p - or create your own custom transcoding preset. Optionally, you can specify thumbnails and job specific transcoding parameters like frame rate and resolution.

While you have transcoding jobs running on Amazon Elastic Transcoder, you can:

• Automatically receive status of your transcoding jobs via notifications.

• Query the status of transcoding jobs.

• Manage your transcoding jobs by stopping, starting or canceling them.

Easy to Use—Amazon Elastic Transcoder is designed to be easy to use. You can get started by using the AWS Management Console, or the service APIs. System transcoding presets make it easy to get transcoding settings right the first time. We provide pre-defined presets to create video files that will play back on a wide range of devices (like smartphones or tablets), as well as presets to create video files that are optimized for playback on a specific device (like the Amazon Kindle Fire HD or Apple iPhone 5). Developers building applications that need transcoding can use the AWS SDKs for Python, Node.js, Java, .NET, PHP, and Ruby.

Elastically Scalable— Amazon Elastic Transcoder is designed to scale seamlessly with your video transcoding workload. Amazon Elastic Transcoder is architected to handle large volumes of video files and large file sizes. Transcoding pipelines enable you to perform multiple transcodes in parallel. Amazon Elastic Transcoder leverages other Amazon Web Services like Amazon S3, Amazon EC2, Amazon DynamoDB, Amazon Simple Workflow (SWF) and Amazon Simple Notification Service (SNS) to give scalability and reliability.

Cost Effective— Amazon Elastic Transcoder uses a content duration-based pricing model: you pay based on the length, in minutes, of the video you are transcoding. For example, if your transcoded output is 30 minutes in duration, you will pay for 30 minutes of transcoding. With Amazon Elastic Transcoder, there are no minimum transcoding volumes, monthly commitments, or long term contracts.

Managed— Amazon Elastic Transcoder enables you to focus on your content rather than on managing transcoding software in a distributed cloud-based environment. The service takes care of scaling and operating the system, and manages the process of keeping codecs up to date and licensing them. Combined with our API and SDKs, this makes it easy for you to build media solutions that use Amazon Elastic Transcoder.

Secure— Your content is under your control: your assets are in your own Amazon S3 buckets, which you give us access to through IAM roles. This makes it simple to fit seamlessly into your current security and identity framework without giving up control. In building Amazon Elastic Transcoder, we made use of security best practices gained by building other Amazon Web Services. For more information about security on AWS, please refer to our AWS Security and Compliance Center.

AWS Integration— Amazon Elastic Transcoder provides an important media building block for creating end-to-end media solutions on AWS. For example, because your transcoded files are stored in Amazon S3, you can immediately stream them at scale over the Internet using Amazon CloudFront and a streaming server running on an Amazon EC2 instance.

Pay only for what you use. There is no minimum fee. Our charges are based on the duration, in minutes, of your output content and whether it is standard definition (SD) or high definition (HD) resolution. High definition (HD) video (defined as having a resolution greater than or equal to 720p) costs twice as much to transcode as SD. If your job fails to transcode for some reason, our policy is to not charge you unless the number of job failures becomes excessive.

Pricing Examples

Amazon Elastic Transcoder offers the following features to make video transcoding easy, scalable and inexpensive.

• Transcoding pipelines: Transcoding pipelines allow customers to setup and run transcoding workflows in parallel. For example, you could set up a pipeline for transcoding short content and another for transcoding long content, or you could assign different pipelines for different resolutions or storage location. You can create up to four transcoding pipelines in Amazon Elastic Transcoder. If you require more than four transcoding pipelines, please contact us using this form.

• Transcoding jobs: Transcoding jobs do the work of transcoding a video file from one format into another. When you create a job, you specify the information that Amazon Elastic Transcoder needs to perform the transcoding: which file to transcode, what to name the transcoded output file and which preset to use. Transcoding jobs run inside a transcoding pipeline, so you can have more than one job running at once within your AWS account. You can have up to 1,000 active jobs per pipeline at any time. If you require this limit to be increased, please contact us using this form.

• System transcoding presets: Amazon Elastic Transcoder provides a set of transcoding presets that removes the guesswork out of figuring out the right transcoding settings for different devices. You can choose from presets that will create output that plays on any device, or from presets that target specific devices. For maximum compatibility, choose a “breadth preset” that will create output that plays on a wide range of devices. For optimum quality and file size, choose an “optimized preset” that will create output for a specific device or class of devices.

• Custom transcoding presets: The transcoding presets that we supply cater to most devices and platforms, but some customers may need to create specific presets for a particular output target. Using custom presets, you can customize an existing transcoding preset and use it across all your pipelines in your AWS account. You can create up to 50 custom transcoding presets in Amazon Elastic Transcoder. If you require more transcoding presets, please contact us using this form.

• Monitoring and Management: You can view the status of your transcoding pipelines and jobs through the AWS Management Console or the Amazon Elastic Transcoder APIs. You can also control your pipelines and jobs by stopping, starting or canceling them.

• Notifications: Amazon Elastic Transcoder uses Amazon Simple Notification Service (SNS) to notify you about transcoding events. You can be notified when your transcoding job starts, when it completes, if there is a warning, and if there is an error condition.

• Thumbnails: Amazon Elastic Transcoder can generate thumbnails of your output video for you. You can set the size of the thumbnails, aspect ratio and other parameters including how many thumbnails you would like to have generated. Generating multiple thumbnails is useful if you want to add chapter markers, provide a visual scan function or simply choose the most representative thumbnail for your content.

• Formats: Amazon Elastic Transcoder supports transcoding into H.264 video and AAC audio in an MP4 container. We support most common media formats for input including H.264, AAC, MP4, MPEG-2, FLV, 3GP and AVI.

• Progressive download of on-demand media: You can store the original versions of your media content in Amazon S3 and configure an Amazon CloudFront download distribution for progressive download of your video and audio files. Popular media files are cached at the edge to help you scale and give your viewers the best possible performance.

• Advanced Settings: You can override defaults or automatic job and preset parameters using advanced settings. For instance, you may wish to force a specific output frame rate, rotation or set a specific H.264 profile level.

• Multiple Regions: Amazon Elastic Transcoder is available in six AWS regions: US East (N. Virginia), US West (Oregon), US West (N. California), EU (Ireland), Asia Pacific (Singapore) and Asia Pacific (Tokyo).
