What is Forensic Video Enhancement?

Forensic video enhancement is the process of clarifying the events using non-destructive techniques in order to preserve the integrity of the pixels and their quality. Clarifying or enhancing the events as they occurred assists the trier of fact to make determinations about the events. 

Surveillance video recordings used as evidence can be enhanced regardless if they were recorded during the day or at night. The success of the forensic video enhancement is directly proportionate to the enhancement techniques, resolution and frame rate of the video evidence.

As a video forensic expert we perform forensic video enhancement services on a daily basis. A video forensic expert is the most qualified professional to enhance events as they occurred naturally. This is due to the fact that we understand how the images were captured, and what processes can be applied without altering the events.Often times we are asked to provide forensic image enhancement as well for identification purposes.

We use basic software tools such as Adobe Premiere as well as advanced enhancement techniques to enhance or clarify video recordings used as evidence. Enhancement is a more common word outside of the courtroom whereas clarification is used in the courtroom. We create customized filtering to sharpen the video image and remove noise. This improves the identification and enhancement of the images in the CCTV Surveillance video recordings.

Our Process


Often times we will perform a preliminary analysis to ensure we  are confident in meeting our client’s expectations. This process requires 1 hour of our lab time in order to apply test enhancements. Once we are confident we can assist, we then enter a full investigation where we can create derivative video exhibits and demonstrative video exhibits. These demonstrative video exhibits include motion based highlighting and/or circling, as well as speed reduction. 

Forensic Video Enhancement Techniques


Each video enhancement investigation is unique, which means no two videos require the same enhancement processes. Often times, enhancement processes are most successfully applied in different arrangements.

As a video enhancement company, surveillance video enhancement or cctv video enhancement is the most common type of enhancement investigation we perform. We also enhance law enforcement dash camera videos, smart phone or mobile video recordings and many more.  The most important ingredient to this scientific process is to maintain the highest quality version of the video evidence. Establishing this chain of custody for quality is crucial to yield the best possible success. This yields the highest success possible throughout the investigation.  The enhancement capabilities of the video enhancement are reduced limited if the analog or digital video has undergone additional video compression processes. 


  • Scaling/Pixel Interpolation: Re-size, or scale an image or video to a larger resolution to further identify suspects.
  • Sharpening: Enhances the edge contrast of an image or video.
  • Warp Stabilization: This is most common today with smart phone video evidence. Reduces the amount of movement from the user that created the video evidence.
  • Shadow and Highlight Adjustments (Exposure): Reveals subtle detail in the shadow and/or highlight areas of your images.
  • Frame Averaging: Increase the quality of the image by averaging pixel data from the highest quality frames from a video recording. Improves the signal to noise ratio (SNR) in your images or videos.
  • Speed Reduction: Decrease the original playback of video evidence to view the events as they occurred in more detail.


Enhanced Video Playback

When a  forensic image or video recording has been professionally enhanced, it is important to identify how the video will be viewed in court. When reviewing the enhanced video recording, it is best to play the video back using the highest quality playback technology. This will ensure that the clarity of the enhanced playback is displayed properly.   Secondly, accommodate the speed of the process as best as possible. Some courts like the Federal Court in Boston have more advanced systems where our work product is easier to view. Other arrangements like projects and big screen TV’s can be made if a courtroom doesn’t have more advanced technologies. This gives us the ability to play the video quickly with features such as slow motion, frame by frame analysis, and zooming capabilities.  We never want to cause a delay in the court proceeding due to technical difficulties.

Presentation In Court

I often provide expert witness testimony services to my clients once a video recording has been forensically clarified. Many courts that I have testified in as an expert witness have video playback equipment. Some of the video equipment that the court provides may not be a high enough quality for higher resolution playback.

For example, older systems may not be bright enough for the trier of fact (judge and jury) to preview from. Double check with the court before hand to determine what playback technology they have available. Bring in any equipment necessary or outsource a company to do so, so the Trier of Fact can easily see and hear your video recording. If you have to rent equipment, make sure it arrives well in advance of the trial.

Is audio a part of your video evidence? Will the jury be able to hear the audio clearly?  Do you need a PA speaker or amplifier system to make the audio louder for everyone in court to hear? It is common when I testify to bring a primary and secondary playback system. The primary system will be the higher quality choice. The backup system is brought in case the primary fails. After all, the main objective is to ensure all video is presented properly and easily heard by all persons in the court room. To learn more tips about presenting video evidence for courtroom use, click HERE.
