5. Analysis Algorithms The HardingFPA HD now features new analysis algorithms which are better tuned to High Definition and File based work They are better suited to subtle changes in the image data and provide much closer results when testing the same material repurposed either into a different video format or encoded with a different codec The main differences between the legacy algorithms and the new ones are detailed below Differences Between v2 5 and v3 0 Different Graph Scaling The HardingFPA HD generates risk values using the same range as its predecessor i e 0 to 3 4 but displays the graphical data using a revised vertical scale This modified scale allocates much more vertical space for risk trace warnings and diagnostic trace steps but only displays risk traces up to the value of 3 0 Risk traces values from 3 1 to 3 4 are still logged as part of the results files but are graphically displayed capped at 3 0 eo rt deen Dana Patterns W Extended Faure W Data Pattern W votes left Version 2 and right Version 3 Graphing The Squiggle The HardingFPA HD gives enhanced visual diagnostics when an incoming transition coincides with an HardingFPA HD User s Manual 15 2010 Cambridge Research Systems Ltd outgoing transition from one exactly second earlier The new version 3 algorithms insert a sguiggle see below to indicate when the diagnostic trace has simultaneously gained and lost a transiti
