The Forensic expert kollegium provides services for conducting video technical examinations. The purpose of such examinations is to determine the authenticity of video recordings (checking for signs of editing, deletion, interruptions, or AI-generated content), identify the recording equipment used, and establish the actual circumstances of the physical environment captured in the video.

During a video technical examination, the expert establishes facts based on specialized knowledge in science and technology, but does not provide legal assessment or qualification of the actions of individuals shown in the video.

Objects of video technical examination:

• video files; 
• data storage devices; 
• video recording equipment; 
• locations or premises.

Cases when video technical examination is conducted:

• investigation of road traffic accidents; 
• criminal and administrative cases where video serves as evidence; 
• identification of individuals in the video; 
• assessment of psycho-emotional state of individuals; 
• identification of recording equipment and its location; 
• cases related to protection of honor and dignity. 

Tasks of examination in road accident investigations:

• image quality enhancement; 
• determining distances between objects; 
• determining time intervals between events; 
• estimating speed of objects; 
• determining feasibility of emergency braking or maneuvering; 
• providing input data for modeling in automotive technical examinations. 

Tasks of examination in criminal and administrative cases:

• video quality enhancement; 
• verification of authenticity; 
• establishing sequence of events; 
• determining presence or absence of facts; 
• identification of objects and locations.

• frame rate;
• noise level;
• amount of material presented, number and nature of fragments;
• presence or absence of metadata;
• data recoding using specialized software, instant messaging apps, or social networks;
• the need to synchronize data from various sources

• Was the video recorded in a residential building at address X?
• What is the diameter of the bicycle wheel shown in video X?
• Are there any drag marks in the video?
• What was the distance between objects X1 and X2 at the moment of citizen M1's fall?

• What device was used to record the video?
• Was the video being examined recorded using this device or copied to a storage device from an external source?
• In what area could the video recording device have been located?
• At what height could the video recording device have been located? Is video surveillance of a specific area conducted when this video recording device is located?

Typical questions when conducting a video examination in cases related to protection of honor and dignity:

• Does video file X.mp4 show any derogatory gestures made by citizen M1 toward citizen M2?
