You need to sign up for a Tencent Cloud account before using MPS.
Log in to the console and go to All Products > Video Services > Media Processing Service.
MPS needs read and write access to COS in order to download and transcode videos in COS buckets as well as upload files to buckets. Therefore, you need to create a service role and grant the role access to COS.
Go to the MPS console, and click Go to CAM to enter the authorization page to grant the access.
You cannot perform further operations in the MPS console before granting the access.
After authorization, you can start using MPS in the console via All products >Video Services > Media Processing Service.
MPS supports two billing modes: daily pay-as-you-go and monthly pay-as-you-go. For details, see Billing Mode.
