In conclusion, VIP2.0 proved to be an invaluable tool in a recent case’s video investigation. When faced with the challenge of multi – channel fused video footage that was fragmented and difficult to analyze, VIP2.0’s multi – channel segmentation feature came to the rescue. The software efficiently split the fused video by channel, enabling investigators to isolate and study each segment separately. This led to the discovery of crucial evidence that was previously hidden due to the chaotic nature of the original footage. Thanks to VIP2.0, key details like the suspect’s escape route and facial features could be clearly identified. It not only streamlined the evidence – gathering process but also significantly boosted the overall efficiency of the case investigation, demonstrating its practical and powerful capabilities in real – world forensic applications.

Case Overview
On the morning of November 9, 2015, a serious homicide took place on a public street. The suspect, driven by a relationship – related conflict, launched a fatal attack on a 28 – year – old woman right in the public eye. Subsequently, the suspect fled the scene in an attempt to avoid arrest. This case quickly attracted extensive media coverage and public attention.
In response, the local authorities promptly obtained surveillance footage from the scene. Investigators pinpointed and isolated the relevant time period, selectively downloading the corresponding video files for in – depth analysis at the investigative agency.
However, when reviewing the footage, investigators discovered that the files consisted of short clips from multiple surveillance channels, each clip lasting just a few seconds. When playing back the key surveillance channels, the short duration of these clips made it hard for investigators to clearly identify crucial details, such as the suspect’s escape route and facial features. This situation posed substantial challenges to evidence collection and the overall case – investigation process.
Case Analysis
The suspect carried out the crime in a public place and made a swift getaway from the scene right after the act. Surveillance footage served as a vital piece of evidence for identifying the suspect and tracking down the escape route. Subsequently, the relevant authorities promptly obtained the surveillance footage from the area and precisely pinpointed the video files corresponding to the time of the incident. However, when reviewing the footage, two major issues cropped up, directly impeding the progress of the investigation:
1）Fragmented Video Format with Multiple Channels
The downloaded video files were in a prevalent multi – channel format, where footage from numerous camera channels was bundled into a single file. When the video was played back, the system would automatically break it into pieces, displaying a succession of short snippets from different channels. This disjointed playback mode made it extremely difficult to continuously and stably monitor a single channel, greatly hindering investigators’ capacity to analyze the suspect’s movements.
2）Rapid Switching Between Critical Footage
Even though investigators managed to pinpoint the time frame during which the suspect showed up on a particular surveillance channel, each video clip lasted merely a few seconds before automatically shifting to the next channel. This quick – paced transition made it arduous for those collecting evidence to capture vital details like the suspect’s facial characteristics, body build, or the direction of escape. As a result, the investigation’s efficiency was severely restricted.
The multi – channel fusion video format is a common feature in certain surveillance systems. However, it creates a major hurdle in evidence collection during law enforcement inquiries. This problem is particularly acute in urgent criminal cases. In such situations, it is crucial to utilize specialized tools that can decompose channels for further processing. Take the VIP2.0 system, for instance. It comes with a built – in channel segmentation tool, which can effectively help overcome this challenge.
As can be observed from the following screenshot, the video is highly fragmented. This fragmentation makes it unfeasible to continuously and steadily monitor a single channel.
Operation Steps
To tackle this problem, the multi – channel segmentation tool integrated within the VIP2.0 (Video Investigation Portable) software developed by Salvationdata offers an efficient solution. The procedure is uncomplicated and doesn’t demand that investigators possess specialized technical expertise. Here are the detailed steps:
1）Open VIP2.0 and find the Toolbox on the top
2）Find the Video Split
3）Import the target video. The default split accuracy is “Normal.”
Reminder: A higher default accuracy setting will yield better image quality during retrieval. However, it might also lead to the omission of some crucial frames. Consequently, in this scenario, we suggest using the normal default accuracy.
5）Click Start Split
6）Wait for the splitting process
7）Save the split videos to the local drive
8）Compare the number of video clips before and after splitting.
- Prior to splitting, there is a single video clip with an approximate total duration of 13 minutes.
2. After splitting, there are nine separate clips from different channels.
Result Explanation
After undergoing processing with VIP2.0, the fused video segment was successfully divided by channel. This allowed investigators to obtain crucial evidence, significantly expediting the case – solving process and earning high acclaim from the client.
Conclusion
This case vividly showcases the indispensable role that high – quality video forensics methods play in resolving complex cases. Conventional surveillance video export methods frequently encounter difficulties when handling multi – channel fused files. These issues include disorderly playback, challenges in identifying channels, and problems with accurately extracting evidence, all of which severely undermine investigative efficiency.
By leveraging the multi – channel segmentation feature of VIP2.0, investigators were able to effectively retrieve key footage related to the case. This instance demonstrated the practical significance of intelligent video processing technologies in real – world forensic applications. The integration of such tools not only streamlined the construction of the evidence chain but also offered essential technical assistance to frontline law enforcement officers.
