Video uploads / Twitter Amplify

[postmodem]

Hi there,

I’m currently adding support in an app for tweeting videos via the REST API.

https://dev.twitter.com/rest/media/uploading-media

According to the documentation, the video must be no longer than 30 seconds.

1. Does this also apply to Twitter accounts that utilize Twitter Amplify?
2. If Twitter Amplify utilizing accounts can tweet longer videos, what is the limit?
3. Is there a way to determine whether an account is part of Twitter Amplify via the REST API?

Thanks for your help.
