Explanation
Amazon Elastic Transcoder is purpose-built for converting media files (video and audio) into formats optimized for specific devices, including smartphones - it handles codec conversion, resolution scaling, and format compatibility automatically. Amazon Comprehend is a natural language processing service for text analysis (sentiment, entity extraction), making it irrelevant to media files. Amazon Rekognition analyzes images and video for content detection (faces, objects, labels), not format conversion. Amazon Polly converts text to speech, so while it produces audio output, it doesn't transcode existing media files.
Memory tip: Think "Elastic Transcoder = Elastic format-changer" - the word transcoder literally means converting across formats, and elastic hints at scaling to many devices/formats, just like other "Elastic" AWS services scale to demand.
