Extract text from RED camera thumbnails (RTN)
To convert RTN thumbnails to another format, you need REDCINE-X PRO or other Raster Image software.
To convert other file formats to the "Camera Thumbnail Image" file type, you need software like REDCINE-X PRO or a similar tool.
The .rtn file extension most frequently represents a RED Camera Thumbnail file used by RED Digital Cinema cameras. It stores low-resolution preview images that accompany massive, high-resolution R3D raw video files. This allows professional grading software like REDCINE-X PRO to rapidly display clip thumbnails without spending system resources decoding the raw video data. Secondary uses for the .rtn extension include Android device diagnostic test routines, which are internally structured as standard ZIP archives containing system logs, and measurement routine files for QVI SmartScope metrology equipment.
The main disadvantage of the RED thumbnail format is that it is strictly proprietary and undocumented. Files cannot be opened by standard image viewers, mobile devices, or web browsers. Users often want to convert these files to a standard format to extract a quick frame grab without installing massive video editing suites. If extraction is possible, the best target formats are JPG or PNG.
Because this is a closed, proprietary format, standard online converters fail to process it. Often, only the original RED software can properly read or export the image data. However, just drag and drop your file to convert.guru to identify the format, view it, and convert it when possible. If our analysis detects a supported underlying or embedded format - such as standard image data inside the thumbnail, or the standard ZIP structure of an Android diagnostic file - viewing or conversion may still be possible.
Convert.Guru analyzes your RTN file, detects the exact format, and lets you read the text inside.
Users also converted RTZ, RTM, RTE, R3D, JPG, CSV, TSX, RAM, BRIDGESORT, APPLE and MID files.
If you want to convert RTN file to MID, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use REDCINE-X PRO or similar software from the "Camera Video Thumbnail Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to RTN, try REDCINE-X PRO or another comparable tool in the "Camera Video Thumbnail 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 RTN converter.
