To reduce the time required to redact videos, use the face detection function to
detect faces, then manually adjust the masks if required.
What you should know
The analytic process begins to search and detect faces whenever a new redaction
process is started.
When the process is complete, a thumbnail image of each detected face is then
displayed, these thumbnails can be used to select the individuals that should be
redacted from the scene.
Masks are applied to all parts of the scene where a face is identified.
The processing time for auto face detection can vary depending on the video file
size and will be affected by the resolution, length, frame rate, and other factors
related to video. The success of the auto face detection can vary depending on the
quality of the video and whether the subject is facing to the front or the
side.
Performing video redaction (Auto Face
Detection) on a mobile device is not supported.
