AWS Elemental MediaConvert now supports Internet Media Subtitles and Captions (IMSC) 1.1 text profile captions. IMSC is a file format that uses XML to describe text, timing, layout, and styling for subtitles and captions. MediaConvert can ingest IMSC text profile sidecar files and can read IMSC from IMF packages. IMSC text sources can be burned in as subtitles, converted to other text-based outputs such as SRT or WebVTT, or output as IMSC sidecar files. To learn more, please read the user guide.

With AWS Elemental MediaConvert, video providers with any size content library can easily and reliably transcode on-demand content for broadcast and multiscreen delivery. MediaConvert functions independently or as part of AWS Elemental Media Services, a family of services that form the foundation of cloud-based workflows and offer the capabilities needed to transport, transcode, package, and deliver video.
