Video Analysis

Digital Surveillance Capturing and Decoding Tool

Digital surveillance video presents unique and often frustrating challenges to a forensic video analyst. Many times the digital file is recorded in a proprietary format and it requires a proprietary player to simply view the file. DVR dCoder solves this problem by capturing a copy of the original and exporting it to an uncompressed open media format such as TIFF, QTIME or AVI.

Demultiplexing Video Tool

Multiplexed Video Explained

Security cameras sometimes store video in a multiplexed video format. Instead of an individual video recorder recording each frame of video to its own individual camera, the security system rotates through the cameras and records an individual image from each camera to a single video recorder. The reordering process goes like this (keep in mind there are 30 frames per second available on NTSC video):

Camera 1/Frame 1 - Camera 2/Frame 2 - Camera 3/Frame 3

Once the rotation is complete, the recording goes back to Camera 1 and starts the whole process over again. Our Studio can isolate individual cameras from multiplexed video. The results are amazing.

Forensic Video Clarification Tool

Many times crucial details are hidden in video due to poor lighting or improperly adjusted and maintained cameras and video equipment. When dealing with color video, details are often more prevalent in one color than another. Magic Motion Studios can isolate the video color space that holds the most valuable information. By analyzing the entire video, or just a region of interest, The studio can adjusts brightness, contrast and gamma to bring out more detail.

Our Forensic Video Clarification Tool removes noise and video graininess through a time-lapse processing technique called frame averaging. When the target remains still for even a moment, video noise and other transient items like rain and snow are removed, revealing the details hidden beneath.

Forensic Mask a Suspect / Agent or Highlight an Area of Interest

Our Spotlight solution allows the analyst to select a region of video highlight or blur. You can define a shape anywhere from a square to a circle, then work with either the inside or outside of that shape using different filters, including blur, mosaic and scatter. All of these filters have a variable intensity setting. You can even apply a border color to the shape to focus more attention on your area of interest. All of the settings can be changed over time, allowing you to track a face or object as it moves as well as adjust your settings to accommodate for the object changing size as it gets closer or further away in the video.


By applying a scatter filter and a red border color, our solution can draw focus to a specific area of interest.	By applying a mosaic or blur, the studio hides specific sensitive information like faces and license plates of suspect and agents.

Quickly Target and Zoom Areas of Video Evidence

Our Zoom solution can take a section of the video and display the results either full screen, or to a user defined portion of the screen. Once the target area is defined, and an output mode is selected, the analyst magnifies the image using the zoom control. The analyst can leave the enlarged image as is, or select a mathematical filter to further clarify the results. The studio can provide independent controls of both target and output borders. These are especially useful when presenting the results in court.
