A Blender user in the U.K. made this recreation of old BBC schedule slides from the 80s. If you're watch it closely, there seems to be some fluttering (or, as the user calls it 'twitter') in the lettering, especially the yellow ones with the black outlines. Does anyone know how to achieve this effect as well as how to create an old NTSC or PAL filter

Create a black and white texture to be used as the interlace.

(I did this in blender with a texture on a plane, but it can be done with any image creation program) enter image description here

Then use that image as a factor to combine different versions of the base image, that have been distressed with different filters.

If you animate the values for the distortion filters or animate an inversion of the interlace texture you can maybe emulate NTSC in all of its glorious ugliness...
