AWS Elemental MediaConvert has added a new feature, IMF (Interoperable Master Format) package ingest, and enhanced an existing feature, caption burn-in, with the addition of several languages. Using MediaConvert, you can now ingest packages with JPEG-2000 video, up to 10 bit UHD format, with IMSC1 text captions. You can pass through HDR (High Dynamic Range) metadata from a CPL (Composition Playlist) to outputs. By taking advantage of IMF, you can reduce asset storage and management costs, and simplify business-to-business distribution workflows for your file-based content. This release of MediaConvert also includes a new high-quality dithering engine, which accepts RGB source files up to 16 bits and is optimized for premium content workflows.
