A blog post by Amazon outlining the technology behind the new video feature says the app supports more than 20 file formats and 40 video codecs:
The team wanted to allow users to upload and view almost any video. The Elastic Transcoder allows them to support more than 20 file formats and 40 video codecs, including videos captured on archaic devices and stored in obsolete formats. Because Cloud Drive already stored uploaded files in Amazon S3 (they also make heavy use of EC2, SQS, SNS, CloudFront and DynamoDB), it was easy for the team to get started. They created an initial set of transcoding pipelines, decided on the set of output formats that they wanted to support, and created Elastic Transcoding presets as needed… In order to provide a great user experience, the team set a goal of having finished videos available 15 minutes or less after they were uploaded. They were able to over-achieve on this goal and report that videos are often ready within a minute or two.
Perhaps Amazon will soon change the app’s name to better reflect its new video capabilities.
The updated app also includes a few other features, including larger preview images in landscape view. Full release notes below:
