Video files have undergone a remarkable evolution over the past few decades, moving from bulky analog tapes to highly compressed digital formats that are easily streamed or downloaded across devices. As this technology continues to evolve, the future of video files points toward even greater compression efficiency, smarter metadata handling, and seamless compatibility across platforms. However, this progress may come at the cost of phasing out some older or proprietary formats. One such example is the 261 file format, a specialized type of video file often used in surveillance systems or embedded hardware setups. While not mainstream, 261 represents a class of formats that face an uncertain future as the digital video landscape becomes more standardized and cloud-centric. Looking ahead, the general trend in video files is moving toward unified formats that balance high-quality visuals with smaller file sizes and broader compatibility. Innovations such as H.
