Syncing 2 ipads to share video content etc

[heisthegaffer]

Hi all

My sister in law has asked me to help her with her two ipads her kids use ahead of a long journey. I rarely use Apple products so a bit lost.

One of them has lots of video content that she wants the other one to be able to watch. They share the same Apple ID and password.

Does this mean this should allow them to sync and share content? If so, how do I enable this to happen?

Thanks
