Server-side ad insertion

Hi,

I am looking to implement a server-side ad insertion solution using either Kaltura CE, Kaltura VPaaS, or otherwise.

Does the Community Edition support server side ad insertion? If so -- where can i find the docs?

Does the VPaaS edition support server side ad insertion?

It's strictly for VOD on web/mobile, there will be no live streaming required.

Thanks for the help!
