SD1 files typically serve two very different purposes, creating a common headache for users trying to determine the correct software to use. The most frequent use (approx. 35%) is as a SuperLab experiment data file, generated by SuperLab from Cedrus Corporation. These files store reaction time data and stimulus sequences used in psychology and neuroscience research. The frustrating part here is the proprietary lock-in; researchers often struggle to analyze this raw data directly without exporting it to SPSS, CSV, or Excel (XLSX) formats first. The format is not human-readable in standard text editors, making conversion essential for statistical analysis.
Alternatively, an SD1 file may be a legacy high-definition video recording from older Samsung mobile phones (approx. 11%). These are essentially MP4 containers masquerading under a different extension, often saved directly to SD cards. Users frequently encounter "File format not supported" errors when trying to play them on standard media players like VLC or Windows Media Player. While renaming the extension to MP4 sometimes works, a full conversion to MP4 or WebP is recommended to ensure the video codec is modernized for web sharing or archiving.

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 SD1 converter.
