Hard Trails

Hard Trails applies a decaying image behind the motion with no transparency applied to the moving object. Hard Trails uses the brightness (luminosity) of the moving object to calculate the trails. To adjust this, you can use the Luminance Threshold and Luminance Range to separate the moving object from the background.

Hard Trails are best applied to a stationary background with moving elements in the foreground.

Tip: For the best results, the moving objects in the video that you want to apply trails to should be brighter than the background.
