Video Redaction

STEP 1: UPLOAD EVIDENCE FILES

  • 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 and Object Detection" to automatically detect heads, license plates or MDTs in videos. Enable "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.

STEP 2: REVIEW DETECTED HEADS

  • Upon completion of the head detection process, you will be able to review the list of detected heads in the right side panel.
  • Enable all Head/Object Detection results by selecting the checkbox below the "Detect Heads and Objects" button.
  • Once all results are enabled, unselect any false positive/unnecessary redactions by clicking on the bounding box within the media player. From here, you'll be able to uncheck the accompanying timestamp from the right side panel. This will remove the redaction from your 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.

STEP 3: CREATE USER-DEFINED REGIONS (UDRs)

  • 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.
  • For redaction of moving heads or objects create a Live Tracking UDR. To do this create your bounding box over the desired area of the file. From there double-click the UDR, this will "lock" the UDR to your mouse cursor. Once Live Tracking is enabled, press and hold the right arrow key to play the video. Follow the object or head along with your cursor for as long as necessary. Once you're finished, double-click the UDR to save your newly created redaction.
  • 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

STEP 4: FIND TARGETED AUDIO FOR 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

STEP 5: PREVIEW YOUR REDACTION AND REDACT 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.

STEP 6: DOWNLOAD THE REDACTED FILE

  • 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.

ADDENDUM: KEYBOARD SHORTCUTS
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.
