Overview

Dedicated transcoding services

Most cloud providers have some form of dedicated transcoding service.service that is specifically designed for that purpose. AWS has Elemental MediaConvert, which lets you run "jobs" to transcode videos to different sizes, and provides an absolute ton of options.

Use cases

ProsTranscoding long videos, or transcoding to high resolutions

For

• Theany transcoding job where a serverless code function isn't powerful enough (which is likely to be a lot of them), a dedicated transcoding service willis your only realistic option. 

  Transcoding at speed

  As dedicated services like this are provisioned with very powerful hardware, to be able to handleperform any tasktranscoding youjob, throw at it, no matter how big

• As it has access to more powerful hardware, itthey will finish transcoding a lotgiven job much faster

Cons

• It's a lot more expensive than using serverless code (for x265/HEVC, it'll cost around 400-500% more!)
• It's harder to set up an automated system around it

Admittedly, the pros and cons are a bit of a moot point, as there aren't any other serious ways to transcode videos that your serverless code function can'will.
