Q: What is Amazon Elastic Transcoder?
Amazon Elastic Transcoder is a highly scalable, easy to use and cost effective way for developers and businesses to convert (or “transcode”) video and audio files from their source format into versions that will playback on devices like smartphones, tablets and PCs.

  • Convert video and audio files for each device
  • Scalable
  • Cost-effective

Q: What can I do with Amazon Elastic Transcoder?
You can use Amazon Elastic Transcoder to convert video and audio files into supported output formats optimized for playback on desktops, mobile devices, tablets, and televisions. In addition to supporting a wide range of input and output formats, resolutions, bitrates, and frame rates, Amazon Elastic Transcoder also offers features for automatic video bit rate optimization, generation of thumbnails, overlay of visual watermarks, caption support, DRM packaging, progressive downloads, encryption and more.

  • Optimize output format for each device
  • Various settings available
  • Thumbnail creation is also possible

Q: Why should I use Amazon Elastic Transcoder?
Amazon Elastic Transcoder manages all the complexity of running media transcoding in the AWS cloud. Amazon Elastic Transcoder enables you to focus on your content, such as the devices you want to support and the quality levels you want to provide, rather than managing the infrastructure and software needed for conversion. Amazon Elastic Transcoder scales to handle the largest encoding jobs. As with all Amazon Web Services, there are no up-front investments required, and you pay only for the resources that you use.

  • No need for infrastructure or software management
  • No initial investment required due to pay-as-you-go pricing

This time, I looked into Amazon Elastic Transcoder.
Here are the key points:

  • Scalable
  • Cost-effective
  • No need for infrastructure or software management
  • Executable via GUI or API

It seems like using the API could be useful for a video conversion app.
It was basic information, but I hope it can be helpful to someone.
