This is the Frei0r tehroxx0r filter.
The effect might not show up during preview but it does appear in the rendered file.
This effect has one parameter — interval — with a range from zero to 1. This parameter controls the number of small video frames which appear around the border and how frequently they flash. Higher number = fewer frames and slower flashing.
