Facial blur and Full blur

Medallia LivingLens provides customers the ability to select video and image files for software-enabled blurring in the LivingLens platform.

The following types of blurring are available:

  • Facial blur — Detects and blurs faces within video and image files.

  • Full blur — Blurs a video or image's full screen.

It is not possible to select and blur a specific part of the media screen.

Restriction: Facial Blur is not available for LivingLens Experience Edition. Contact your Medallia Representative for more information.

Facial blur and Full blur are typically used to meet personally identifiable information (PII) or reporting requirements or when customers are unable to secure respondent permission to use their media.

Best practice is to source respondent permission to use media in advance of upload.

Facial blur

Facial blur detects faces within video and image files. The software tracks the detected faces within a video file to blur each face from all angles. The rest of the video or image file renders normally.

The software most easily detects and tracks unobstructed front-facing faces. This view provides the best results for facial blurring. It is more challenging to detect and track the following:

  • Faces shown from a side angle

  • Face that represent a small proportion of the screen

  • Pixelated faces

  • Faces in small resolution/poor quality media

Media with Facial Blur applied can be reprocessed with Full Blur.

Full blur

Full blur distorts the whole video or image file. The main use case for Full blur is when Facial blur is unable to detect and blur all faces in a media file.

It is not possible to revert a Full blur to a Facial blur.

Creating blurred media

Facial blurring is available on a per video/image basis with the ability to multi-select relevant media. Selecting media for blurring is a manual process. It is not possible to automate the selection process.

Tip: The blur selector opens over the media displayed in the Media Library. Before clicking Select Media, filter to a subset of media, such as by Media Source, Country or Language, to apply blur to that subset.
To select and blur individual media:
  1. On the Media Library screen, click More Actions and select Facial Blur or Full Blur.

  2. Navigate through media and select each media item for blurring by clicking the media thumbnail. Selected media has a check mark.

    Selecting media will not begin blur processing. Media will not blur until you click Save.

  3. Click Save to start blurring the selected media.

  4. Depending on the type of blurring, review the Facial Blur Confirmation or Full Blur Confirmation modal.

    a. Click Confirm to process blurring.

    b. Click Cancel to return to blur selection.

Each media thumbnail image displays Processing... until blurring is complete.

To use Blur All:

  1. On the Media Library screen, click More Actions and select Facial Blur or Full Blur.

  2. Click Blur All. This selects all video and image files.
  3. Depending on the type of blurring, review the Facial Blur Confirmation or Full Blur Confirmation modal.

    a. Click Confirm to process blurring.

    b. Click Cancel to return to blur selection.

Each media thumbnail image displays Processing... until blurring is complete.

The following video shows how to use Facial blur.

The following video shows how to use Full blur.

Using blurred media

Blurred media is the default view of the media file. On the Media View page, Customer Admin, Channel Admin and Pro users can view the unblurred version of the media by clicking ICON Toggle blur on the media player's right side menu. Users can download both the blurred and original video or image file from the download menu.

Standard users can only view the blurred version of media.

There is no automatic process for reverting a blurred video or image to the original as the default view for all users. However, Customer Admin, Channel Admin and Pro users can download an unblurred version of the media and re-upload it to the channel.

Blurring media creates a Standard filter for each media file in LivingLens. Use the Blurred Status filter to view Facial, Full, or Not Blurred media in the Media Library.

Blur and showreels

Blur media prior to creating a clip or showreel. Each clip in a showreel has the level of blurring (Facial or Full) that has been applied in advance of making the clip.

Note: Showreels and clips cannot be processed for blurring. Full video and image files must be blurred in advance of making a clip for the showreel.

Blur and analytics

Facial blur and Full blur do not impact Facial Emotion Analytics and Object Recognition. These analyses take place as part of media ingest, before media is available for blurring in a channel.
