Shotcut Video Filter: Persistence

Author: Elusien©2019 (www.elusien.co.uk/shotcut) Licence: MIT

Persistence is a Shotcut Video Filter that simulates motion blur. It is not true motion blur but is similar to what you see at night if you look at a small light, de-focus your eyes then quickly move your head from side to side. You see multiple persistent images of the light. The parameter can be key-framed (see the screenshot below). If you set the parameter to 0% you will see no persistence, if you set it to 100% you will see only the first frame. Try setting it to 50%, then modify the value up ir down to get the effect you want.

Filter Parameters
Name Description
Strength The strength of the persistence as a percentage.
