SafeStream Workflow

Automatic Privacy Protection and Content Enhancement for Lecture Recordings

Published

November 20, 2025

Overview

The SafeStream Workflow automatically protects student privacy and enhances lecture recordings: Kai reviews your lecture, suggests edits, and you approve with one click. No more manual video editing, no more privacy concerns, no more boring dead air. SafeStream ensures your recordings are FERPA-compliant, engaging, and ready to publish—all with minimal effort from you.

How It Works

Record your lecture as usual, get notified when processing is complete, review suggestions, click submit—your video is automatically edited and published:

SafeStream Workflow - Automatic Privacy Protection and Content Enhancement

TipThe Entire Process in 3 Simple Steps
  1. You Teach - Lecture capture records your class as normal
  2. You Review - Get push notification with Kai’s edit suggestions
  3. You Click Submit - Video is automatically edited and published

That’s it! No manual editing, no privacy worries, just clean, engaging content.

Workflow Steps

1. Standard Lecture Capture

  • Regular lecture recording during class
  • No change to your teaching routine
  • Capture ends when class concludes

2. Intelligent Processing

After lecture ends, Kai automatically: - Analyzes the entire recording - Identifies personally identifiable information (PII) - Detects periods of dead air or silence - Flags content requiring privacy protection

3. Push Notification

  • Instructor receives notification when processing complete
  • Alert indicates video is ready for review
  • Includes summary of recommended edits

4. Review Interface

Simple editing interface shows: - Privacy Concerns: Student discussions about grades, personal information - Dead Air Segments: Setup time, breaks, long pauses - Exam Detection: Full lecture flagged if exam activity detected - Suggested Actions: - Cut completely (red strike-through): Removes video segment entirely - used for dead air or sensitive blackboard information - Mute audio (grey text): Video continues playing but audio is silenced - used for PII or grade discussions - Cut entire lecture: When AI detects an exam taking up the whole class period - Visual Timeline: Clear markers showing suggested edit points

What Happens When You Submit: When you approve edits, the system automatically: - Reprocesses the video on the server - Cuts out segments marked with red strike-through (dead air, sensitive content) - Mutes audio for segments marked in grey (PII protection) - Removes entire lecture if exam was detected - Re-uploads edited video to your LMS or CHI platform - Notifies students that new content is available

5. One-Click Approval

  • Review all suggestions at a glance
  • Modify if needed (optional)
  • Click “Submit” to approve edits
  • Kai automatically applies all approved changes

6. Automatic Reprocessing & Publication

After you approve edits, the system: - Reprocesses the entire video with approved changes - Cuts segments completely (for dead air or sensitive blackboard content) - Mutes audio sections (for PII or grade discussions) - Removes full lecture if exam detected - Uploads edited video to LMS or CHI platform - Makes content available to students - Maintains original recording in secure archive
