VIDEO FORENSICS EXPERT SERVICES
Video evidence can appear straightforward while still containing timing errors, compression artifacts, missing context, or details that are difficult to interpret.
4D Forensics examines surveillance footage, body-worn camera video, dashcam recordings, mobile video, and other sources to clarify what the recording supports, identify its limitations, and present the findings in a form that legal teams can use.

When Video Forensic Analysis Can Help
Video analysis is often useful when the recording is central to a disputed sequence of events or when the legal team needs more than ordinary playback. Common questions include:
- Can the timing of an event be verified?
- Do several cameras show the same event from different perspectives?
- Can a person, vehicle, object, or movement be compared across frames?
- Is the apparent motion consistent with the frame rate and playback speed?
- Has the video been converted, edited, re-encoded, or otherwise changed?
- Can the footage be aligned with audio, dispatch records, sensor data, or a 3D scene?
The goal is to determine what can be supported through careful examination of the available evidence.

MULTIPLE RECORDINGS
We evaluate the submitted evidence to determine whether it is the original file, native proprietary export, or first-generation capture. Often, screen recordings, emailed copies, converted files, and social media downloads may reduce image or audio quality and remove valuable metadata. If that is the case, we can identify the likely source and format and assist in locating, extracting, or recovering the most complete and forensically reliable version available.
How a Video Examination Works
1. Case & Evidence Review
We begin with the legal or investigative question. The scope may involve enhancement, timing, comparison, authentication, synchronization, spatial analysis, or preparation of demonstrative exhibits.
2. Preservation & Evaluation
The submitted files are documented and evaluated for format, codec, frame rate, resolution, timestamps, metadata, and signs of conversion or recompression. Working copies are used for examination while the submitted evidence is preserved.
3. Forensic Analysis
The examination is tailored to the evidence. It may include frame-by-frame review, stabilization, image sequence comparison, object tracking, timeline alignment, compression analysis, camera perspective evaluation, or video-to-3D alignment.
4. Findings & Presentations
Results can be delivered through a written report, clarified clips, annotated stills, synchronized timelines, comparison exhibits, demonstrative media, consultation, deposition, or testimony, depending on the engagement.

What You May Receive
- A written explanation of methods, observations, conclusions, and limitations.
- Enhanced or clarified video prepared from a documented working copy.
- Selected still frames and annotated exhibits.
- A synchronized multi-camera or multi-source timeline.
- Comparison media for a subject, vehicle, object, or event.
- Technical support for deposition, mediation, hearing, or trial.
What Video Enhancement Cannot Do
Forensic processing can improve visibility, reduce distraction, correct playback issues, and help an examiner study information already present in the recording. It cannot reliably reconstruct fine detail that the camera never captured. Results are affected by resolution, focus, motion blur, distance, lighting, frame rate, compression, export quality, and the availability of the original source.
A defensible conclusion may sometimes be that the recording does not support a requested identification or measurement. That limitation can be as important to a case as a positive finding.
Frequently Asked Questions About Video Forensics
Should I send the clip/data that was produced in discovery or request the full export?
We can use the initial submission and assess whether it is a complete, native export or a converted or shortened version that may omit frames, timestamps, metadata, or surrounding context. If a more complete or proprietary export is needed, we can identify the appropriate format and assist with requesting, extracting, or recovering it from the original recording system.
Can several videos be synchronized?
Yes. Synchronization may use visible events, audio events, timestamps, frame timing, or other shared reference points. The accuracy of the alignment depends on many factors. We can help identify the reliable data points to use.
Can you identify a person or license plate?
Sometimes. We can assess whether the recorded detail is sufficient for comparison or clarification. We do not promise an identification before reviewing the source. Low resolution, motion blur, distance, glare, compression, and obstruction may limit the result.
Can you determine whether a video was edited?
A technical authentication examination can evaluate file structure, metadata, timing, encoding, compression behavior, and other indicators. The strength of any conclusion depends on the file provided and the known history of the recording.
