By default, the "Watch the video" link in a work item points to a publicly unlisted video hosted on Microsoft Stream via SharePoint. This setup provides secure access and automatic transcript support, while still allowing easy sharing with people inside and outside the organization.

SharePoint vs YouTube Hosting

SharePoint (Default - Recommended)

• Security: Full control over video access through your organization's SharePoint instance
• Scalability: No daily upload limits
• Integration: Seamless integration with Microsoft ecosystem
• Transcripts: Automatic transcript support
• Best Practice: Links expire after 30 days for security and content management

YouTube (Optional)

• Permanence: Videos don't expire (unlike SharePoint's 30-day default)
• Public sharing: Better for content that may be shared outside your organization
• Limitations:
  • Daily quota of ~100 video uploads per channel per day
  • Less secure - if unlisted links are accidentally shared, anyone can access them
  • No organizational control over access permissions

Note: SharePoint's 30-day link expiry is a security best practice. For high-volume usage or when permanent access is required, YouTube hosting is available but comes with daily upload limits and security considerations.
