With AWS Elemental MediaConvert, you can now create Common Media Application Format (CMAF) fragmented MP4 (fMP4) HLS and DASH video outputs. With CMAF support on AWS Elemental MediaConvert, you can create a single file format using the AVC (Advanced Video Coding) or High-Efficiency Video Codec (HEVC) codecs and fMP4 segments that are then packaged and delivered as multiple adaptive streaming technologies to serve different devices. Support for CMAF lets you realize video quality improvements and benefit from simplification of content creation and storage. You can also now create HEVC content for Apple devices with improved video quality and better compression efficiency over AVC, and use High Dynamic Range (HDR) for premium video experiences.
