Appendix A: Metadata File Format

The metadata and video version of this solution can ingest metadata files that are in XML or JSON format. The metadata file is used to configure the Amazon Elastic Transcoder. The file must include definitions for srcVideo, upscaling, thumbnails, watermark, and at least one output format (HLS, DASH, MP4).
