Your website is serving on-demand training videos to your workforce. Videos are uploaded monthly in high
resolution MP4 format. Your workforce is distributed globally often on the move and using company-provided
tablets that require the HTTP Live Streaming (HLS) protocol to watch a video. Your company has no video
transcoding expertise and it required you may need to pay for a consultant.

    I would say B
    you need SQS because the videos are uploaded monthly.
    Using S3 and auto-archiving to Glacier will be much efficient and cost effective process.

    AWS Elastic Transcoder

    Amazon Elastic Transcoder is a highly scalable, easy-to-use and cost-effective way for developers and businesses to convert (or “transcode”) video files from their source format into versions that will play back on multiple devices like smartphones, tablets and PCs.
    Elastic Transcoder is for any customer with media assets stored in S3 for e.g. developers creating apps or websites that publish user-generated content, enterprises and educational establishments converting training and communication videos, and content owners and broadcasters needing to convert media assets into web-friendly formats.
    Elastic Transcoder features
    can be used to convert files from different media formats into H.264/AAC/MP4 files at different resolutions, bitrates, and frame rates, and set up transcoding pipelines to transcode files in parallel.
    can be configured to overlay up to four graphics, known as watermarks, over a video during transcoding
    can be configured to transcode captions, or subtitles, from one format to another and supports embedded and sidebar caption types
    provides clip stitching ability to stitch together parts, or clips, from multiple input files to create a single output
    can be configured to create Thumbnails
    Elastic Transcoder is integrated with CloudTrail, an AWS service that captures information about every request that is sent to the Elastic Transcoder API by your AWS account, including your IAM users
    Elastic Transcoder Components

    Presets
    are templates that contain most of the settings for transcoding media files from one format to another.
    Elastic Transcoder includes some default presets for common formats and ability to create customized presets
    Jobs
    do the work of transcoding and converts a file into up to 30 formats.
    takes the input file to be transcoded, names of the transcoded files and several other settings as input
    For each transcoded format a preset needs to be specified
    Pipelines
    are queues that manage the transcoding jobs.
    Elastic Transcoder starts processing the jobs and transcoding into format (for multiple formats) in the order they are added.
    can be paused to temporarily stop processing jobs
    Notifications
    help keep you apprised of the status of a job, i.e. started, completed, encounters warning or error
    eliminate the need for polling to determine when a job has finished and can be configured during pipeline creation

    option:A
