AWS Elemental MediaConvert now supports rich text rendering of IMSC 1.1 text profile subtitles and the TTML subtitle format. Both of these formats allow detailed formatting that includes text size, position, justification, color, styling, and shadowing. For many viewers, on screen subtitles are an important part of the viewing experience and this feature gives subtitle authors more creative control of how text is rendered on screen. Additionally, IMSC and TTML allow greater text localization options including right-to-left text, rubies, and vertical text.

For more information about configuring subtitles in MediaConvert, including the new style-passthrough feature for IMSC and TTML, please see the documentation.

With AWS Elemental MediaConvert, audio and 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 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.
