12. Media Services
These services manage the complex ingestion, transcoding, and delivery of high-quality video content. Exam weight note: Media Services is a very lightly tested domain on SAA-C03 — expect at most a passing recognition question, not deep scenario analysis. Don't over-invest study time here relative to Compute/Storage/Networking/Database.
Elastic Transcoder vs. AWS Elemental MediaConvert (if it comes up at all): Elastic Transcoder is the older, simpler transcoding service shown here; AWS Elemental MediaConvert is the newer, more feature-rich file-based video transcoding service AWS now steers most new broadcast/OTT workloads toward (broader codec/format support, more professional workflow features). If an exam question describes a large-scale, professional broadcast/OTT transcoding pipeline, MediaConvert is more likely the intended answer than Elastic Transcoder even though MediaConvert isn't detailed as its own entry here.
