Video Redaction


  • Click ‘Upload Media’ to upload evidence files into Redact.
  • A file picker will appear, allowing you to drag-and-drop your files or browse to choose a file for upload from your local computer. 
  • Next, check the box next to each processing option that you'd like to run: Choose "Run Head Detection" to automatically detect heads in videos and/or "Run Transcription" if you'd like to review and redact audio as well.
  • Once uploaded, click on the newly-created video tile to open the file to begin the redaction process.

Tip: Files cannot be renamed once they've been uploaded, so please ensure that your files are named as desired prior to uploading.


  • Upon completion of the head detection process, you will be able to review the list of detected heads in the right side pane.
  • For any item in the list, click on the time value to forward the file playback to that specific point-in-time.
  • If you'd like to select a specific head for redaction, click the checkbox to the left of any item in the list.  A green bounding box will then appear on the file player at the exact point-in-time during which the head was detected.
  • Continue this selection process for any heads that you'd like to redact from the evidence file.
  • Be sure to click the "Save" button at the button on the screen to save your work.

Tip: To select only certain instances of a specific head for redaction, you can expand its item in the list by clicking on the down arrow to its right and individually de/selecting frames or simply de/selecting all frames.


  • For additional redaction of missed heads or other objects / PII requiring redaction, begin drawing a bounding box by positioning your cursor in the desired area in the file player and then hold left-click while dragging with your mouse until a yellow bounding box appears around the desired area.
  • Once you've drawn your UDR, you can extend it for the duration of the video by left clicking the bounding box, selecting the overflow menu that appears at the bottom of the video player, and choosing either the "Track forward in time" or "Track all time" option.
  • For static areas on screen, that need to be redacted for the entire length of the video, draw the UDR directly on the video and then click the down arrow next to the UDR bar in the timeline. From here you can extend the UDR by clicking the yellow bar and dragging to the desired length of the video file.
  • Continue the process of drawing and extending UDRs until you've drawn bounding boxes around all of the areas that require additional redaction.
  • Be sure to click the "Save" button at the button on the screen to save your work.

Tip: The "Track forward in time" option will extend the UDR for the remainder of the video's duration (from the UDR start time to the video's end time), while the "Track all time" option will extend the UDR throughout the entire video duration (from the video start time to the video end time).

Audio Redaction


  • Click the "Audio" tab in the right pane.
  • In the search bar, enter keywords or phrases that you'd like to find in the transcript and its corresponding audio.
  • Right click any of the highlighted search results in the transcript viewer to redact a specific instance or all instances of the found keyword or phrase.
  • Alternatively, you can highlight any portion of text in the transcript by left-clicking, holding and dragging your mouse. Then, right-click your mouse on this selection to redact the highlighted text.
  • Be sure to click the "Save" button at the button on the screen to save your work.

Tip: You can also add a note to any audio redaction by right-clicking the redacted text and selecting the "Edit Note" option.

Generating and Downloading a Redacted Copy of the File


  • To preview the results of your redaction, click the play button on the media player and ensure that heads, UDRs and audio are redacted as desired. If not, now is the time to make any adjustments.
  • After you've made any adjustments and you're ready to generate the redacted version of the file, click the "Redact File" button.

Tip: Generating the redacted version of the file will take a variable amount of time, depending on the duration of the file and the number of redactions.


  • Once the process to generate the redacted version of the file has completed, click the "Redacted Files" Tab at the top of the screen.
  • Then, click the "Download" button to save a copy of the redacted file to your local computer.

Tip: The download file will be a .zip archive. The contents of the zip archive will include the redacted video or audio file, as well as a CSV-formatted audit log of all user actions that took place on that file.

To increase the speed and efficiency of the redaction process, you can use keyboard shortcuts instead of your mouse within the Redact application. A quick reference to these shortcuts can be accessed by clicking the keyboard icon at the top of the screen. We've also included this quick reference below.
