Extract text from Thermal image sequences (CSQ)
To convert CSQ Thermal sequences to another format, you need FLIR Tools or other Video software.
To convert other file formats to the "Thermal Image Sequence" file type, you need software like FLIR Tools or a similar tool.
The .CSQ file extension is predominantly used for FLIR Thermal Image Sequence files. These are proprietary files created by thermal imaging cameras manufactured by FLIR Systems. Unlike standard video files, a .CSQ sequence contains continuous raw radiometric data, meaning every pixel in every frame records an absolute temperature measurement rather than standard RGB color data. Less commonly, .CSQ files may act as a database query file for TEKLYNX CODESOFT label software, or represent an encrypted, quarantined malware file generated by Symantec Security Software.
The massive disadvantage of the .CSQ format is its proprietary nature. You cannot play a .CSQ file in standard media players like VLC, nor can you view it directly in any web browser. Accessing and analyzing the raw temperature data requires heavy, specialized desktop software like FLIR Thermal Studio or legacy FLIR Tools, which often require expensive paid licenses.
Users typically need to convert .CSQ files into standard video formats like MP4 or AVI to share thermal recordings with clients, or to CSV to export the underlying raw temperature grid for data analysis. However, converting to a standard video format comes with a major tradeoff: you will permanently lose the embedded radiometric data, retaining only the visual representation of the chosen thermal color palette (like Ironbow or White Hot).
Because .CSQ is heavily closed-source and undocumented, standard online converters completely fail to process it. Only the original proprietary software can fully read the radiometric mathematics involved. We can inspect the file headers and extract internal content. If our analysis detects an underlying video stream or standard embedded visual format, viewing or conversion to MP4 or JPG may still be possible through our platform.
Convert.Guru analyzes your CSQ file, detects the exact format, and lets you read the text inside.
Users also converted CQS, PKPASS, BMT, IRI, FS and MP4 files.
If you want to convert CSQ file to MP4, you can use FLIR Tools or similar software from the "Thermal Image Sequence Storage" category. In the File menu, look for Save As… or Export….
To convert files to CSQ, try FLIR Tools or another comparable tool in the "Thermal Image Sequence Storage" category.
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 CSQ converter.
