How to: Using Enhancement Effects When Redacting a Video or Image With CaseGuard Investigate

CaseGuard Studio includes 30+ enhancement effects designed to improve clarity or strengthen concealment when you redact images or videos. These effects work alongside our AI video redaction & our AI image redaction tools, allowing you to sharpen, magnify, blur, brighten, or otherwise enhance footage directly within the platform.

Each effect includes an intuitive intensity slider, giving you complete control over how the enhancement appears in your video or image. For example, objects closer to the camera may require a stronger blur for proper concealment, while distant or low-quality footage may benefit from higher levels of sharpening or magnification to reveal important details.

Every CaseGuard license includes access to all enhancement effects, and they can be stacked to create a customized result. This flexibility makes CaseGuard Investigate especially powerful for investigators who need to improve visibility in dark, blurry, or fast-moving footage. Many agencies use these enhancement effects to clarify critical moments in surveillance or body-worn camera video, supporting investigations and helping solve cases more efficiently.

Shapes

CaseGuard has 5 different shapes available for redactions.

  • Rectangle
  • Triangle
  • Ellipse
  • Diamond
  • Polygon

Select the shape you would like to use for your redaction from the Tool Properties Panel.
