Unfortunately AV Studio and Epiphan Cloud are two completely different functioning platforms. Epiphan Cloud is a cloud-based fleet and remote management platform for the Pearl family of products. It allows for additional remote functionality such as start/stop of recordings and configured streams - as well as basic RTMP stream creations, remotely accessing the Web UI, monitoring device health, email notifications and more.
Webcaster integration on the legacy AV Studio platform provided a cloud-based recording option, when network bandwidth was a concern for streaming. You had the ability to create video projects from those recordings with basic editing options and download the completed video projects for consumption. The cloud-based recording and editing features were not ported over to the Epiphan Cloud platform, which focuses on fleet and remote management.
As Webcaster X2 was rendered legacy in March 2020, development resources have been refocused towards existing and new product lines, which means X2 is unfortunately not integrated with Epiphan Cloud or its RTMP streaming options dedicated to the Pearl family.
