2D Generator - Generate alternating black and white frames

A glitch consists of a constant flash: every odd frame is a full black image and every even frame is full white.
This generator is used to determine the quality of the video output (to debug e.g. vertical synchronization or frame rate issues).
With a good quality output, a Glitch layer should be appearing flashing very regularly way, without never having any grip, freeze or latency in the signal.


  • Frequency (Frames per second (FPS)) : Frequency of the glitch (50Hz by default)
  • Period in Frames (Positive Number (> 0) (Optional)) : If enabled, specifies the frequency of the glitch in number of frames
  • Color (Color) : Color of the flash
  • Glitch (On/off option) :
