AUDIO & VIDEO FORENSICS SERVICES
It’s hard to imagine a modern day without video surveillance cameras, smartphones, tablet cameras, dashboard cameras, action cameras, and body cams. Thousands of cameras capture thousands of different events. Like unbiased witnesses, they are ready to share what they saw. Thus, when it comes to
As a result, video recording can contribute to uncovering the truth only with the involvement of video forensic experts. They leverage their expertise and specialized equipment to ensure that video recording can serve as uncontested and informative evidence during legal proceedings. Experts need to overcome many challenges and even simple videos can present significant problems. There are dozens of modern digital recording formats and analog recordings (for example, VHS). In most cases, law enforcement agencies and courts have tools that can reproduce data only from a handful of formats.
Converting video to a necessary format cannot be accomplished by simply consulting Google or downloading suitable conversion software. Innumerable surveillance system models have their own video formats without user-friendly and easily obtainable converter formats. Even if these conversion tools exist, there’s no guarantee that conversion will not destroy the image’s microscopic details that will be critical in the future. Only an expert with video coding training and reliable video forensic equipment can guarantee
Retrieval of necessary information often requires more than just viewing of the video. For instance, multiple cameras can record the same event. If recordings are reproduced one after the other, it’s hard to match details. It’s much easier to accomplish this by analyzing all recordings simultaneously. But, first, recordings need to synchronized. Synchronized recordings can simultaneously reproduce the same events. This process allows to view events from different angles and capture critical details. Expert involvement is also critical when

Taking all these factors into consideration, it’s not guaranteed that a video can clearly capture car license plate or criminal’s face
When it comes to forensic video enhancement, it’s naïve to expect a miracle from an expert, similar to stories shown in fictitious crime shows. However, modern video enhancement software can sometimes produce miraculous results.
FORENSIC VIDEO ENHANCEMENT
One of video forensic expert’s main responsibilities is the determination of video’s authenticity and
This complex task is accomplished through two phases. During the first phase, forensic expert evaluates the video to determine whether it is an original or a copy. The term original video is only used to refer to the video captured on the device during recording. Copying can simply mean that the video file was copied on a different device, the device that was not used during video recording. Copying can also refer to editing file format, resampling
The best way to distinguish between an original and a copy is to obtain a video copy recorded on the same device as a video in question. Discovering recompressed video raises a red flag for a video forensic expert. Video recompression can indicate video editing.
As a result, the most complicated part of authenticity determination is finding remaining evidence of counterfeit video. Sometimes, easily observed simple artifacts can serve as this evidence. For instance, a suddenly appearing object in the video frame or hands of a clock that rapidly changed to a new time can prove that the video is a fake.
Professional forgery is not easily detectable without special tools such as modern forensic software. In this case, forensic experts can conclude video’s authenticity by closely inspecting various qualities of the video, such as video format, coding parameters, file structure, metadata, and, more importantly, verification of image in every one of tens
From time to time, experts are presented with a new challenge – source camera identification. This challenge can be tackled in the same way for pictures and videos. Camera ballistics technology is not very difficult. Experts
Forensic expert’s contribution doesn’t stop even after proving video’s authenticity, video enhancement and
Thus, object identification comes into play. In order to solve this issue, experts need to find identifying characteristics using an image. These characteristics need to distinguish an image from thousands of similar images. Next, it’s vital to compare verifiable object’s characteristics against duplicate object’s characteristics. This job is similar to a child’s Spot the Difference Game. Forensic expert’s ability to skillfully play this game can impact the destiny of stakeholders involved in video investigation.
However, advanced spatial geometry is not always enough. Luckily, modern computers have the capability to produce 3D models of the geographic area and objects. Forensic engineers can determine several points with known coordinates on video or images, easily calculate coordinates of other points, and determine
distance between these points.
An image can demonstrate a distance between two objects. A video can also determine
Video forensics can’t solve all riddles. However, experts know that even the tiniest details can make a significant impact during an investigation. Video forensic experts can’t always be magicians, but they still try to work toward a miracle.
