Forensic audio & video enhancement services include:

Forensic audio clarification & digital sound cleaning and clarification

Do you have hard to hear recorded audio that you want cleaned up? We got you covered! Removing or reducing hiss, buzz, hum, and other background noise and audio disturbances while maintaining speech clarity is part science, part art. It requires specialized digital audio software created for forensic sound filtering and restoration, as well as a skilled, experienced ear. The right forensic audio expert trained on the latest digital equipment and software will create for you a version of your audio with reduced noise to allow you, a jury, and your judge to hear the evidence better. Listen to audio samples of before and after our filtering.

Creating accurate transcripts of dialogue that are trusted in court

After filtering, amplifying, and cleaning up recorded audio evidence, our expert legal forensic team is sometimes asked to analyze and create a transcription of the recorded audio, detailing every word heard, for our clients to present in court. NCAVF experts are ready and available to testify about their expert opinion.

Metadata analysis

When a computer file is saved, it is not only the content of that file which is saved, but also data about that newly saved file -- the date and time the file was saved, potentially where the person was at the time the file was saved, the format of the data, equipment used in the creation of that data, software being used by the computer which saved the data, and much more. That data about the data can be very helpful after a crime is committed because it can help police to track down suspects.

Video filtering and forensic digital video brightening

Brighten dark video images, sharpen and clarify details, improve contrast in dark images, repair damaged video signals, filter unwanted/background sound, stabilize shaky video, and correct wobbling video. Our video and audio experts are ready to help. See still-images taken from a video that shows our low light and dark scene correction.

Slow motion and frame by frame forensic image analysis

Video usually records at 30 frames per second, and sometimes a fast moving event can only be seen by slowing down the footage. The forensic video and audio experts at NCAVF will work with you to find those individual video frames which demonstrate your case and then apply proper video filters and enhancement software to make those frames as clear as possible.

Still image enlargement

Still images can be created from the video and blown up into a large poster size picture for attorneys to use as evidence in court. Lawyers may wish to play a recorded video on a large flat screen TV, and they also may desire to pass around an enlarged single frame poster size still image from the video when speaking to a jury during a court case.

Determining the height of a suspect or measuring the distance between two points seen in security camera video

When the identity of the suspect is in question -- for example, when the suspect's face is never seen in a video -- knowing the height of the person seen in a security surveillance along with the clothing worn can sometimes help with a case. NCAVF recreates the scene of a crime in a 3D computer model, using specialized crime scene reconstruction software, to help determine measurements of key evidence, including the height of the suspect. See example of height determination.

Preparing video and audio evidence for ease of presentation in court

Preparing digital video and audio evidence for easy, mistake proof use in court, both for attorneys to utilyze during trial and for juries during deliberations, is crucial to ensuring your case gets a fair hearing. See images of our easy-to-use DVD menus

(Tip for success: Once the evidence is ready, it's also crucial for an attorney to practice with the video and audio playback system to be sure your presentation goes smoothly and accurately.)

Video production for court demonstration

There are many uses for video in court. Nothing is more convincing to a jury than seeing the facts with their own eyes, and watching video is second best to being there, firsthand.

When you wish a jury could visit a location, but you know that is not possible, then bring the location to them! Create a video that presents the location of the alleged illegal activity, help them visualize the scene of an accident, demonstrate how new construction blocks customers from reaching a business, explain the details of a demolition site or a landfill, and show with video the details of construction fraud to support your real estate lawsuit.

Attorneys call our legal video team to video record crime scenes, construction sites, demolition sites, eminent domain targets, and to record property for insurance purposes.

Call NCAVF to videotape and save details of a location that might soon disappear. Allow us to edit that video and create an easy-to-use custom DVD or video files on a USB Flash Drive that will be useful evidence in court.

Courtroom consultation & AV tech setup

NCAVF can consult and assist attorneys in the proper setup of playback technology in the courtroom. Proper sound reproduction and clear, bright video projection ensures that your jury views the digial evidence in the best possible way. Without it, your jury may not understand the evidence properly.

Presentation of digital evidence such as security camera videos or police belt recordings or 911 calls to a jury often requires setting up courtroom audio and video playback with professional speakers and displays. And NCAVF can also be brought in to operate the equipment during trial.

Research of technical evidence

Often our clients don't understand how the technology used in recording evidence in a case might help them -- computers, security cameras, recording systems & software settings -- the experts at NCAVF speak the language and help you investigate and discover background technical information that could help your case. We assist in describing -- simply and clearly -- that information first to you, and then, later, to your jury. Were the cameras up to date and cleaned properly? Was the computer software program setup correctly and calibrated to capture the evidence? Are there frames missing from the recording? Is this missing video information important? Are the activities seen on the surveillance camera in reality closer than they appear on the screen? Does the surveillance recording show the event in the same way as it was seen by the participants during the incident?

Forensic time line mapping and sequencing of events

It may be important to explain evidence to a jury with clear visual aids such as legal timelines.

Expert witness testimony in courts for civil and criminal litigation

Once the video and audio forensic work is complete, we analyze the results and can testify about our forensic video work in court.
