Microsoft has just announced a new portal called the Office 365 Video portal. Office 365 Video provides an easy way to upload, encode and distribute videos within your enterprise.
Uploading a video is as simple as dragging and dropping a video or uploading from a mobile device:
The service uses Azure Media Services to take an uploaded video (which you can do just by dragging and dropping into a video library) and encoding it for a variety of playback standards for multiple devices.
Videos also will be fully integrated into the existing social features of Office 365 including Delve’s discovery search engine and Yammer conversations.
