8-bit JPG
The 8-bit JPG format of the Duo Pro R is exclusively a compressed image as seen on the video output,
and has no thermal data available for post processing. The 8-bit image has user Scene and Palette
processing applied
,
as well as Spot / Scene Meter if enabled. If a compatible flight controller is
available telemetry will be captured and saved in standard metadata fields.
Files have a “_8b.jpg”
extension. This format is not suitable for mapping nor later data analysis.
This file type only appears when a snapshot is captured during video recording.

Infrared: Video File Types
6.3.1
14-bit (RJPEG)
A 30Hz video file where every frame is an RJPEG. This file format is compatible with FLIR Tools
and ResearchIR, and allows users to edit radiometric parameters such as emissivity and
background temperature in post-processing.
Radiometric parameters such as subject emissivity and distance can be adjusted in post-
processing using FLIR Tools or ResearchIR software, giving maximum flexibility to adjust & edit
measurement data in post-processing.
Each video frame has unique metadata, such as GPS coordinates, associated with it.
6.3.2
14-bit (TIFF)
A 30Hz video file where every frame is a TIFF. This file format is compatible with many image
processing tools, such as MATLAB and ImageJ. To convert the values to temperature (Celcius), see
section 6.2.2.
Radiometric parameters such as subject emissivity and distance cannot be adjusted in post-
processing.
There is only one set of metadata associated with the entire file, recorded at the start of the video.
