XDAQFrameData is embedded into camera frames captured by XDAQ AIO and streamed live to a PC via Thunderbolt. Each recorded frame contains both the JPEG encoded image data and its associated XDAQ metadata.

File Extension

PtsMetadata is saved as a flat binary file, containing continuous metadata associated with video frames for further metadata processing.
