AI-powered redaction for video, images, and audio

Bug Fixes

• Empty Video List after License Exchange (Desktop)
  Desktop app now refreshes the video list after license reactivation, so videos remain visible without restarting.
• Speaker Labeling
  Fixed speech detection speaker labels so numbering is contiguous and always starts with 'Speaker #1' based on first appearance.

‍

New Features

• Speech Transcription Improved
  Introduced a new engine for which the detection and accuracy of speech have been vastly improved. Installers and Docker images have shrunken in size, the english language is onboard, other languages can be downloaded after installation.
• Speaker Diarization (beta)
  Using speech detection one can also now attempt to detect who spoke. Speakers are identified, can be labeled, corrected and merged. This allows selection and redaction of certain persons. This is our first best effort release, fine tuning and adjusting it over the next releases will be ongoing.
• New Speech UI
  • New editor-like overall look and feel.
  • Maximized view, alternative to the side bar one.
  • Enhanced text search and selection (words, regexes, speakers, inversion, ...)
  • Export in multiple text formats (raw, JSON, ...)
  • Speaker identifier management (reassignment, relabeling)
  • Display options (colors, transparency, word presentation, ...)
  • Live animation of currently played words.
• Work Time Tracking
  Redactor can record how long editors actively spend on each session, with a start/stop clock and a live HH:MM:SS readout in the editor and a running total in the server video list. Administrators and supervisors can reset a video's recorded time. The actual time data is exported in the audit logs of a session.

Updates

• Richer Audit Archive
  The "Acquire Audit Data" archive now includes an info.json manifest describing the archive's origin (host, network addresses, and user) and, for each session, a SHA-256 checksum of its audit log together with the video's metadata. The creation and inclusion of history.gz has been removed due to performance issues (needs to be revisited).
• Smoother Editing of Long Transcripts
  The speech editor stays responsive on very long transcripts (an hour of audio and thousands of words), removing the lag that could appear when opening the panel or during playback.
• Smoother Waveform Zoom
  Zooming the audio waveform with the mouse wheel or a pinch gesture now redraws smoothly instead of stuttering during rapid zooming.
• Consistent Playback-Speed Picker
  The video playback-speed control now looks and behaves the same across browsers and the desktop app.
• Live Track Recordings Recovered After Disconnect
  A manual Live Track recording is no longer lost if the connection to the server drops before you click Apply. In-progress recordings are now staged periodically and committed automatically if the connection is lost. (The desktop version was not affected.)
• Session Preservation For Missing Video Files
  If video files are missing (most common case a different mount for the videos folder) sessions will no longer be removed but all of their data preserved. On the next start a rediscovery attempt will be made and if video files are back their associated sessions be restore.
• Corrupted Data Healing Improved
  Measurements have been put in place to correct corrupted redaction (e.g. due to bugs or other circumstances).

Bug Fixes

• License Availability Count
  A license with a fixed expiry date could incorrectly report zero available seats. Seat availability is now calculated correctly.
• Empty Context Menu in Videos List
  In the video, when selecting multiple files, the not selected entries showed an empty context menu stub.
• Admin Storage Shows Zero Bytes
  In some deployments the admin showed zero bytes storage usage, this has now been corrected.

New Features

• Out-of-Disk-Space Protection
  When disk usage on the app data folder exceeds the threshold, the server replies with HTTP 503 to all requests except /health and resumes automatically once it drops. Configurable via REDACTOR_OODSTRACK_THRESHOLD_PCT (default 90%) and REDACTOR_OODSTRACK_INTERVALS.
• Memory Diagnostics
  A new tracker samples heap usage and logs new high-water marks, and can write a V8 heap snapshot when usage exceeds a configurable percentage of the heap limit. Controlled via REDACTOR_DIAG_OOMTRACK_INTVL, REDACTOR_DIAG_OOMTRACK_DUMP_PCT, and REDACTOR_DIAG_OOMTRACK_DUMP_PATH.
• Optional Persisted Redaction History
  Per-session history persistence is now opt-in via the new REDACTOR_HISTORY_ENABLED env var (default 0=off), reducing disk I/O for high-throughput API workloads. For in-depth audit logs you might want to set it to 1.

Updates

• Server Stability Internal optimizations got added to make the backend more robust and responsive under concurrent API (and sometimes regular user) load.
• Operational Logging
  Active session and operation counts are now logged on each change, and OS resource limits are logged at startup.

Bug Fixes

• KeepAlive Interval with Polling Transport
  Setting REDACTOR_FORCE_POLLING_TRANSPORT=1 could hit the server with too many keepAlive POSTs. This is now back to regular, recommended intervals.
• Box Border Visuals
  The borders for background / keep-unredacted boxes did not render properly. The original visual concept got improved for better visibility.
• Reaction to Malformed Requests
  All effective endpoint flows are now validated thoroughly against malformed traffic (observed on publicly-exposed/non-firewalled hosts)
