Cloud Transcoding with Amazon Web Services

Cloud transcoding allows for the conversion of video files between different encoding formats. This is useful when the target device or workflow does not support the original format or file size. Cloud computing is well-suited for the CPU-intensive task of video encoding. There are two main types of cloud transcoding - video on demand (VOD) transcoding of pre-recorded content, and live transcoding of streaming video. VOD transcoding reduces on-site encoding costs while live transcoding addresses bandwidth issues and allows for adaptive streaming. Amazon Elastic Transcoder and EC2 Spot Instances are two options for VOD transcoding in AWS.
![Cloud Transcoding: perchè ?
Transcoding is the direct digital-to-digital data conversion of one
encoding to another […] This is usually done in cases where a target
device (or workflow) does not support the format or has limited storage
capacity that mandates a reduced file size [Fonte: Wikipedia]
Cloud computing is uniquely suited for the
CPU-intensive and "bursty" nature of video encoding

- 3. Cloud Transcoding: Vod e Live • Vod Transcoding: compressione di contenuti audio e video pre-registrati • Riduce i costi di encoding on-site • Live Transcoding: compressione di stream live • Risolve il problema della banda in out • Streaming live adattivo (HDS, HLS, MPEG-DASH, Smooth streaming) • File vod immediatamente disponibili
