About SEC files
The .SEC file extension primarily represents proprietary video footage recorded by Samsung DVR (Digital Video Recorder) and NVR systems, specifically the SRD series. These files contain H.264 or MPEG-4 encoded video streams wrapped in a proprietary container for security and tamper-evidence purposes. While excellent for legal admissibility, .SEC files pose significant challenges for general playback; they are often incompatible with standard media players like VLC media player or Windows Media Player and cannot be uploaded directly to YouTube or viewed on mobile devices.
To view this footage on standard devices or edit it in software like Adobe Premiere Pro, users must convert the .SEC file to a universally supported format like MP4 or AVI. Users often encounter "codec missing" errors when trying to open these raw streams.
Secondary Formats: The .SEC extension is also frequently used for: 1. PGP Secret Key Rings: Stores private encryption keys (Pretty Good Privacy). These cannot be "converted" to media but can be exported to ASCII armored text (ASC). 2. Safe Exam Browser (SEB) Config Files: Encrypted configuration settings (often ZIP-compressed) used to lock down computers during exams. 3. GuinXell video files or Stata scripts.
For the Samsung video files, convert.guru allows you to strip the proprietary wrapper and transcode the stream into a standard MP4 for immediate viewing and sharing.

The SEC Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SEC converter.
