Smart Phone Video Enhancement

WHAT IS SMART PHONE VIDEO ENHANCEMENT?

Smart phone video enhancement is the process of applying scientific applications to a video recording in order to better see the events as they occurred. Smart phones record video events such as an accident or crime.

We forensically clarify or enhance to better see these events. In the following paragraphs, we hope to communicate some information that will guide you on forensic video enhancement.

We have included some before and after forensic enhancement examples for your review. We also include advise on what to do to best capture an event in for forensic enhancement.

Most people recrod smart phone video evidence freehand or without a tripod, so you can’t guarantee the video usability. When people are nervous they shake while recording. In this case do not zoom in too much. A wide shot is less shaky than a zoomed in shot. Shaky video can result in less than quality video evidence.

RECORD VIDEO HORIZONTALLY OR LANDSCAPE

When recording video on your smart phone, hold the phone horizontally and try not to zoom in. One of the most prevalent problems we have seen with video recordings are they shake and are not stable. The chaotic motion of a cell phone video can make it hard to see what’s happening.

FORENSIC VIDEO ENHANCEMENT

The two clips below will help you understand how video forensic video enhancement works. The first clip is of a forensically enhanced iPhone video. The original video was a distant view from down the block as it was recorded. In the sample below, please note no stabilization or other forensic enhancement has been applied to this video.

In the enhanced sample below, we applied warp stabilization. Notice how the frame follows the motion of the video, creating a more stable picture for analysis.

As you can see, the subject in the video was not close enough to the smart phone camera. This makes it difficult to see the desired events as they occurred. Clip one is not very helpful in this condition for use in court. The subjects are very far away, making it difficult to see the recorded events as they occurred.

THE SCIENCE OF FORENSIC VIDEO ENHANCEMENT

The forensic video enhancement process is not as simple as zooming in on the video recording. This will lower your overall video quality. Fixing it or enhancing your video isn’t nearly as simple as pushing the enhance button on your computer.

Reduced video quality occurs when you zoom in and has to do with pixels. Simply put, pixels are the small boxes of color code that combine to make up a given image. Each image is a series of pixels that display the image you see in front of you.

Expanding an image means also expanding the size of each pixel. Because each pixel is representative of one ?frame? of a bigger picture, such as photos making up a collage, each individual square pixel will expand along with the image. The increase of pixel size can cause distortion to the image, therefore making it even harder to decipher the contents of an image.

How can Forensic Video Enhancement Help Investigators?

How can forensic video enhancement help investigators? In this blog post, we’ll explore its benefits and why there is a growing need for it in today’s court system.

Forensic video enhancement is the scientific approach to clarifying a video recording in order to better see the events as they occurred. It can help litigators understand events that are difficult to see because of excess movement, distance, or the video is too dark. For example, CCTV cameras outside retail stores helped the FBI capture the terrorists who were responsible for the Boston bombings.

Videos often need forensic enhancement because cameras are not properly maintained. This is a huge problem that goes unnoticed until after the crime has been committed. Or, worse yet, the cameras are not installed or positioned properly. Read on for a few facts on forensic video enhancement.

Forensic Enhancement Editing

ORIGINAL VIDEO

Perform a color correction process first before performing any other forensic enhancement process. This is especially important if your video recording is dark. Be careful not to add too much brightness.

COMPUTER SOFTWARE

Perform a color correction process first before performing any other forensic enhancement process. This is especially important if your video recording is dark. Be careful not to add too much brightness.

COLOR CORRECTION

Perform a color correction process first before performing any other forensic enhancement process. This is especially important if your video recording is dark. Be careful not to add too much brightness.

ENLARGEMENT

If you need to enlarge a portion of the recorded video viewing area, apply after you review the footage on a large video monitor. At Primeau Forensics, we use minimum 27 professional video monitors. Remember, the larger the playback monitor, the better you can see events in the video and the less you need to enlarge your video as an enhancement step. This is even more important in the courtroom.

EQUIPMENT

It is good to know the type of equipment that made the video you are enhancing. Often times, a poor CCTV video export may be to blame for the poor video quality. If the recording is stored on the system, we can make sure we have the best export to work with for forensic video enhancement.

Forensic video enhancement is an art as well as a science. Please understand that you should use different filtering to get different results. Always begin with the largest file size and structure as close to original digital video recording as possible.

Creating Video Work Products as an Audio/Video Forensic Expert

Video Forensic LabVideo work products are a way to document forensic investigations, such as evidence recovery, for reference at a later date. A video camera documents processes and procedures during a forensic investigation for future use. I have referred back to my video work product many times when I have questions later during the evolution of the case.

As an audio & video forensic expert, I have examined hundreds of audio and video recordings to determine authenticity, as well as enhance characteristics of the digital evidence. This video work product helps clarify the events as they occurred.


Types of Video Work Products

There are a few different digital video recording platforms that I use when creating video work product. I often use VIEVU body worn cameras and HDSLR photography based cameras. Each of these of systems serves a purpose in assisting with a forensic investigation.

Over the last few years, I have seen firsthand the significance and efficiency that body worn cameras and their recorded video can bring to the public, law enforcement, and legal proceedings. I personally use the VIEVU LE2 and LE3 body worn cameras. The LE3 records in 720p HD resolution and utilizes a 68 degree field of view. Other competitor cameras normally use a 130 degree field of view, which captures a wider field of view but less detail. And when it comes to video evidence, details are usually more important.


LE3 Body Worn Cameras

These body worn cameras also contain digital audio recorders, which record MP3 format audio at a 44.1kHz sampling rate and a 64kbps bit rate. This high sampling rate captures the full range of human hearing, making recorded audio more audible. In some cases, a client lawyer or law enforcement agencies require that videos record zero audio.

The LE3 audio recorder switches off separately from the video, providing flexibility in such a situation. The LE3 records to either MP4 or AVI video format for easy playability across various platforms utilizing the H.264 codec. These formats also allow easy integration into forensic programs, such as the Adobe Production Premium Suite. The 16 GB flash style storage system allows for either 12 hours of SD video or 6 hours of HD video and quick data transfer rates. The battery will last 5 hours during SD recording and 3 hours during HD recordings. The unit is also compatible with an external battery pack for extended battery life.

My main use for the LE3 body camera is recording my forensic process in the field. This includes retrieving evidence from different systems so I can review later and include it in my report. This supports the authenticity of my work product and any evidence used in the case. Often times, a forensic expert will be challenged by a client or opposing lawyer to verify the investigative materials’ chain of custody. Even minor details on how the investigation was conducted can have a large bearing on the authenticity of the evidence. A digital video recorde allows me to capture a video of the investigative process and dialogue explaining it. Including this work product to my forensic reports verifies the chain of custody and protects me as a forensic expert.


HDSLR Photography Camera

Another type of digital video camera that I use to produce video work product is an HDSLR photography camera. This type of equipment has become popular among the scientific community, as well as production companies, for its portability, versatility, quality, and functionality.

An HDSLR photography camera uses different size lenses to capture images and video depending on investigation requirements. HDSLR cameras record in 720p, 1080p, anamorphic and even 4k resolution. These cameras typically record at 30 minute intervals and have a battery life of approximately 2 hours, depending on the preferred quality and the available storage space. When connected to an external power source, these cameras record for longer intervals of time. HDSLR cameras are great for recording an alternative perspective to body cameras of an investigation or retrieval process. The flexibility of being able to produce individual still images as well as video throughout an investigation is also helpful with my forensic process.

In some investigations, a single perspective may not be sufficient to display the forensic process or document events. Another high-quality camera with perspective flexibility and interchangeable lenses can capture investigative aspects that body cameras cannot. Additionally, this lockdown feature of a point-and-shoot camera allows an investigator or client attorney to view the process as if they are watching in real time.

Another use for HDSLR cameras is recording accident reconstruction videos. An accident reconstruction video is a recreation of an event in the same environment they occurred. This allows them to be shown to a client investigator, client attorney, or law enforcement. It is most effective to show the real life series of events as opposed to 3D animation or a written statement.


CCTV Surveillance Systems

Closed circuit television (CCTV) surveillance systems have been the dominant source of video evidence during my 30 years as a forensic expert.

Video evidence produced by CCTV systems can help reproduce accidents and disasters as they occurred for playback in different settings. One significant use a forensic expert has when recording video from a CCTV system is to create an exemplar. An exemplar recording is a recording made in the most similar way possible to the original piece of evidence. It uses the same equipment, settings, environment and conditions of the original evidence. Used as a comparison file to the original evidence, this recording helps determine authenticity. A forensic investigation compares both the quality of the video and the metadata included in the files.

It is a best practice at Primeau Forensics to video record forensic investigations. For example, we record our exemplar creation processes and evidence recovery. As a result, we can reference this video work product if our client has any questions during the life of their case.

The Palace Brawl: The Significance of Video Evidence

palace brawlNovember 19, 2004 was the day the worst sporting brawl in US history took place. It was the final few minutes of the basketball game between the Indiana Pacers and Detroit Pistons when a fight broke out between the players. While Ron Artest was in time out, a drunken fan tossed a partially full beer cup and hit Artest causing him to jump over seats and attack a fan in the stands. With tempers running hot, Artest went after the wrong person and triggered an ‘every man for himself’ situation with only four Auburn Hills police officers in the building.

After the criminal litigations were over, the attorney for the Pacers, Steve Potter retained my services as a video forensic expert on behalf of the Indiana Pacers basketball team. My first activity was to collect all of the available video footage from that moment when the brawl broke out. As you can imagine there were many video sources. With the help of http://www.potterlaw.com/, I found cell phone videos, CCTV system videos from the Palace of Auburn Hills, and four major television network multi-camera video sources.

The next task was to cull through all the footage including multi-camera views of the brawl and isolate those vantage point views that helped bring the brawl into the courtroom for the civil litigation.

I was prepared with several video clips when the first civil case went to trial, Haddad V Indiana Pacers on August 10, 2006. (Read all about it here).

Here are the video forensic activities I used to help the Trier of Fact and jurors view the brawl including all isolated incidents in question. After I received all video footage, I loaded the various formats into my forensic computer using Adobe Premiere Pro software. I created sequences for each incident and placed the useful camera vantage point clips back to back in each sequence. Some events went by very fast so I repeated the video clips and added slow motion. In some cases, I reduced the speed by 25%, 50%, and 75% so all persons could see the series of events as they occurred. When necessary, I also zoomed to enlarge the area of interest in each video clip.

In my opinion, it is very important to place this series of clips back to back with a 5-second pause in between clips so the viewer can become acclimated with the series of events as they occurred. For each clip vantage point, there was an average of two to five minutes of video all persons could watch to see exactly what went down during the brawl.

Video Enhancement: How to Enhance a Video Recording

video enhancementAs experienced and trained video forensic experts, we perform video enhancement in our lab on a regular basis. In the following post, we will share with you some common challenges with forensic video enhancement process. We will also share some ‘How To’s’ so you better understand the forensic video enhancement process.


Video Enhancement Preliminary Analysis

Client attorneys submit video recordings to us for preliminary analysis. During this phase, we spend one hour of lab time to review the statistics of the video recording. We examine the compression, pixels, format and aspect ratio to name a few. During the preliminary analysis, we communicate to our client whether or not forensic video enhancement is possible. Nobody should pay high forensic laboratory rates until a forensic expert believes a video recording can be enhanced.

The main reason we are called many times every day here at Primeau Forensics for video enhancement is that our clients want to better see the events as they occurred. This is mostly because they want the truth about an event, crime, or altercation.


Purpose and Goals for Video Enhancement

One of the goals of forensic video enhancement, in some cases, is to be able to see person’s faces better than they are when viewing the video without video enhancement. In this case, a comparative analysis is performed after video enhancement in an attempt to determine the identity of a person in a video recording.

Other reasons for forensic video enhancement is to enlarge and clarify a video in order to identify, for instance, the license plate on a car. This is more difficult, especially if the car is in motion and the camera is not near the license plate. When the car is not moving and the license plate is in close proximity to the camera, a video forensic expert can use frame averaging to combine the best pixel quality for successful video enhancement.


Audio Enhancement for Video Recordings

Audio portions of video recordings can also be enhanced to help an investigation. On occasion, audio portions of video recordings fail or are not clear. In the laboratory, we can remove the audio portion of a video recording and forensically enhance the audio to better hear the events as they originally occurred.

With forensic video enhancement, we can only enhance what is possible to enhance. Hollywood has distorted the public perception of what can be enhanced forensically and what is impossible to forensically enhance.

In some cases, the video is of too poor quality for forensic video enhancement. Some reasons for low video quality include; the video recording was not exported properly and the camera lens is dirty (keep your outdoor cameras clean).

Frame rate is set low in the digital video recorder will also lower the potential for successful video enhancement. If the video recording size (aspect ratio) is small, we have a lower chance for successful video enhancement. We can not zoom and clarify the objects of interest. These objects become blurry and distorted. Even while using the best forensic video enhancement tools and software programs available, a successful enhancement isn’t always possible.


We Ask Questions About Your Video Recording

When we initially speak to a client-attorney, government agency, or private individual, we ask a lot of questions about the video recording. Is the video recording still stored on the system that created it? This is always the best practice when a video recording has captured a crime. That way, a video forensic expert can be brought in to examine the recording system and video quality to make sure we have the highest quality of video recording for video enhancement. We have learned to ask a lot of questions before our clients spend any money that may be wasted. We always make sure we have the best quality export from the system or device that created the video recording when performing forensic video enhancement.

At Primeau Forensics, we have a team of trained forensic experts, forensic technicians, and investigators that work on a daily bases with all kinds of video recordings.


How to Enhance a Video Recording

This section is designed to better help you understand the forensic video enhancement process. One tip that we can present to you, as previously mentioned, is to make sure you always have the highest possible quality export from the equipment that created the video recording. Types of equipment that create video include a CCTV surveillance system, mobile video surveillance device, police dash camera, police body camera, and smartphone to name a few. Another tip is to keep the video recording stored on the device that created the video recording.

There are methods for recovering video recordings for forensic video enhancement. A more desirable method is exporting the highest quality video recording. Another is to play the video recording while simultaneously recording the video onto another device. Here is another tip, do not use your smartphone to record the playback screen of a video surveillance system and expect a successful video enhancement.

Police departments often send us video recordings created on a surveillance system that were not exported through the equipment that created it but rather recorded out of the equipment onto another device. Once the device plays the recording while another device simultaneously recordings the playback signal. An output like ‘VGA’ is used which records the same quality that can be viewed on the systems video monitor. This is much better than recording the screen with your smartphone. Some of the time this is the only way to get a video recording exported from the system that created it.


There are several companies that manufacture turnkey evidence retrieval systems.

In some cases, a simultaneous video recording is better than what the system that created the recording is capable of exporting. When in doubt, it is best to perform both processes and send us both versions. Screen capture or VGA as well as an export from the system. To further explain, an export is a process that can be verified in the operator’s manual of the system.

Call the manufacturer of the surveillance system tech department if you need help. Do not wait too long and risk the important video recording to be erased or overwritten. Put the export on a thumb drive and make back up copies. Do not change the file format or any other settings when making copies.

Video as Evidence – CCTV Video and Video Forensics

CCTV Evidence

As a video forensic expert and expert witness, I have seen almost everything when it comes to CCTV. Some of it is very disturbing, but much of it is from the lady whose ex-husband is stalking her, to the bank that just captured a robbery on video. Understanding CCTV systems has become part of the video forensic examiner’s job because a majority of video evidence is made on CCTV systems. In the following article, I will give you my forensic tips on CCTV.

Imagine this. You are the proprietor of a convenience store. Last night at 11:06, you rang up a customer’s Snickers bar and a jumbo Slurpee. The customer reached in his pocket, pulled out a gun, and put it to your head, demanding all the cash in the register. Terrified for your life, you gave him the money. Luckily you had a CCTV system and turned the tape over to the police. The police sent it to a forensic expert because all you could see on the tape was a dark silhouette of the criminal. Unfortunately, the robber’s face and features were unidentifiable.

Although CCTV systems can prove to be beneficial for many reasons, they can be useless without some well thought out considerations. My hope is that the law enforcement and legal community will read this article and pass on the information to the businesses in their community.

CCTV is a network of cameras hooked to a monitoring system so that various locations or angles can be viewed and/or recorded. It does differ from broadcast television in that CCTV cameras are not openly broadcast through the airwaves. However, some CCTV systems have point-to-point transmissions that could be intercepted by someone with the equipment and knowledge to intercept that signals.

The benefits outweigh the drawbacks of implementing CCTV systems for several reasons. Think of how CCTV systems have helped our traffic problems. Having cameras all over our roads and highways allows accidents and traffic jams to be discovered sooner so traffic can be rerouted. In banks, casinos, airports, shopping centers, businesses, and military bases; CCTV systems can prove beneficial against crime.

There are some drawbacks that can really cause problems with CCTV systems. These systems can be expensive. They can be considered an invasion of privacy. Also, a system can fail because of a bad or over-recycled tape, and the crime will not be recorded.

For some strange reason, businesses who still use VHS tape to record their surveillance often insist on recycling their videos beyond a logical limit. Then, when the expert needs to lift an image off for identification, fuzzy, blurry photos are produced.

In the convenience store example above, the camera was in the wrong position. A light was installed in a recently added display that was not in the store when the CCTV system was installed. Nobody ever updated the CCTV system or performed maintenance to discover the problem.

The purpose of this article is to share some of my experiences with CCTV footage and provide some tips from a forensic expert’s point of view, sound advice to avoid costly mistakes, and expensive forensic restoration.

Number One: Plan your CCTV system layout in advance. Do not put in a CCTV system without planning for potential crime circumstances. What crimes could be executed under the watchful eyes of your CCTV system? You can call this crisis management. Draw a diagram of this activity. Use it as your blueprint for locating your camera positions. If you own a business that has a back lot to cover, don’t just mount the camera to the back of your building thinking it will do the job. Consider what you have to protect, the value of these items, and the various ways a criminal could get at them. Then, place the camera(s) to cover all potential activity. Consider multiple cameras because, in the long run, it will save you money.

Because so many systems were not planned thoroughly in advance, the majority of my forensic cases involve video restoration and clarification. So much of this can be avoided.

Number Two: Use a digital video recorder and record directly to the hard drive. If at all possible, do not use VHS. There are some great companies like Focus Micro and Crest electronics that specialize in DVR CCTV systems, maintenance of the system, and training your staff to use them properly. They offer some excellent products and CCTV systems, and will even help you plan your system layout.

Here are some reasons DVR is superior to VHS:

  • Far better image quality
  • The ability to view cameras, live or recorded, from another location through the internet
  • Ease in copying images from crime scenes
  • No VHS tapes to change

Number Three: Make sure to account for lighting conditions, as well as sun positions.

One out of ten of my cases requires the comparison of a frame of evidence from a darkly lit video with an exemplar frame or photo. Make sure there is light where your camera is located. If necessary, hire an electrician to put in a light or two near your camera, especially if the potential crimes that warrant the installation of your CCTV system can occur at night. Duh! I can hear the installed now: sure looked good in daylight!?

In addition, consider sun positions all year long. Remember sixth-grade science class? The sun changes positions with the seasons. Bright sun facing the camera will cause the iris in the camera to close (in automatic position) causing the image of the perpetrator to darken. Try this with your home camera. Take a video of your friends with the un behind them instead of behind you. The friends will appear dark because of the camera’s lenses adjusting for the high light level.

Number Four: Plan camera positions for all possible situations. I have heard it said that if you want to rob a bank, wear a baseball cap. Why is it that CCTV installers put the cameras in high positions that will never show the criminals face?

Number Five: Keep your camera clean. Car dealerships wash their windows and cars weekly if not more often. Why don’t they wash their cameras? Think about it. Many outdoor cameras are somewhat protected from the elements, but after a while, dirt will still gather on the surface of the camera lenses.

A solution of Shaklee basic H or white vinegar in hot water will clean them nicely without scratching or clouding the lenses or protective housing. Harsh cleaning chemicals can scratch or cloud the glass, especially on Plexiglas camera housings.

Number Six: Do not use wireless cameras. If at all possible, run cable and go wired for your entire network. Wireless cameras are unreliable, especially in storms.

Almost all maintenance can be performed by you or done very reasonably by a professional. Avoid costly mistakes and tragedy by keeping your system maintained and updated. Use Google to seek a professional who can help with your circumstances.

CCTV Enhancement: How to Improve the Quality of Video Evidence

CCTV EvidenceYou have a video and the quality is poor. You need to see the events recorded in the video more clearly than what is currently available. Chances are that your video is probably part of a court case and has a critical impact on the judge and jury better understanding the events as they originally occurred. Video is a very powerful tool and helps law enforcement display criminal activity in the courtroom. Video also helps keep businesses secure through the use of surveillance video. When a crime is committed and caught on CCTV video, video forensics experts can help clarify and enhance that video so the court and other litigators can see the events more clearly during the court proceeding. On the other hand, maybe you have an old video, like a wedding video that has aged and damaged from poor storage or became overheated on the dashboard of your car in the hot sun. Video forensic experts have the hardware and software tools available to restore that video to a playable condition in most situations. The success of the restoration, clarification, and enhancement, depends on two things; how damaged the tape is and your expectations of what is possible. Many video recordings are too far gone for the forensic expert to properly restore. However, I have found over the years that experimenting with various restoration tools, hardware, and software, in various combinations, yield results. You have to have a starting point to work from to achieve results. What may seem impossible can be very possible when using various tools in various combinations. If you have a video that needs the quality improved, call us for a pro bono consultation (800) 647-4281.

Expert Video Enhancement: A Matter of Life or Death

video enhancement As we have all witnessed from the recent Boston Bombings, having the technology and talent to accurately and clearly perform expert video enhancement. This is especially true when it comes to criminal forensic image clarification from surveillance security cameras.

A trained specialist using sophisticated software can make blurry or seemingly impossible-to-see images so clear that unique facial features are revealed, leading to positive identification of a suspect or criminal.

The FBI engaged a team of experts to enhance images of the two bombing suspects to the point of positive recognition. As a result, several friends and family members of the suspects came forth, providing valuable information to the authorities.

Within 24 hours after the enhanced photos were released, suspect one was killed and suspect two was captured. The power of video enhancement prevented an unknown amount of possible additional deaths by the two bombers. Watertown residents can feel safe in their homes once again.

At Primeau Forensics, we have a team of video forensic experts that employ the latest technology available to enhance surveillance video. We investigate video evidence that helps the court better see the events as they occurred working closely and strategically with authorities like police or prosecutors as well as lawyers.

We have the technology and experience to acquire clear images, measure objects and suspects, and the ability to look for other clues in the surveillance video to aid in the litigation or criminal proceeding.

If you have any questions about video enhancement, give us a call for a pro bono consultation at (800) 647-4281.

Video Enhancement Strategies of a Video Forensic Expert

video enhancementEvery case that requires video enhancement requires the video forensic expert to develop a strategy comprised of a series of steps and forensic software tools. Back when surveillance video was an analog videotape, video enhancement was more difficult. The equipment forensic experts used to conduct video enhancement was entirely hardware-based. Forensic experts did the best they could with what they had to work with.

Today, technology has progressed, making several scientific community-approved software programs available. One thing that causes difficulty during video enhancement is poor camera placement.

Installation of CCTV cameras must be well thought out in advance in order to aide in the forensic investigation, should a crime be committed. In addition, the sun constantly moves throughout the day and affects the surveillance video camera by over and under-exposing the surveillance area.

Outdoor cameras become dirty after a period of time, making video enhancement difficult. Point Tilt Zoom (PTZ) cameras provide much better video surveillance footage because of their ability to move, follow and zoom in on perpetrators more effectively than surface mount cameras. An ounce of prevention is worth a pound of cure. Making sure the surveillance system is properly thought out and installed will make video enhancement more successful than trying to fix problems that could have been avoided.

I do not have to convince you of the value of surveillance video; the number of court cases that have video forensic evidence speaks for themselves. Surveillance video recordings produce very useful high-quality digital video recordings that aide litigators in the courtroom see the events as they originally occurred.

Video enhancement is challenged by one thing: the fact that most security video recordings must be viewed on a proprietary player, a software program that has the ability to interpret the specific manufacturer’s secure code, which maintains the integrity of the video recording, keeps the video secure and reduces the vulnerability of editing. This proprietary player makes it very difficult to alter or edit the surveillance video. Some manufacturers allow the ability to export video files from their surveillance propriety players and others do not. This poses a challenge for the video enhancement expert.

The best bet in any situation that requires video enhancement is to talk to an experienced video forensic expert to learn what is possible and what is not. Video enhancement is misled by what Hollywood produces and often confuses the public as to what is possible and what is not.
