Create jitter effect

Looked at the video.
You want a posterize time effect.
Can be done.

Timelapse Effect - "Posterize Time"

I sometimes use Premiere’s “Posterize Time” effect, basically say you have a 24fps clip, if you set the Posterize Time effect to 2 it’ll make it look like it’s only 2fps by only showing 1/12 of all frames. Then by setting the speed to 1200%, it makes it look like a timelapse. Is there anyway to reproduce such an effect in Shotcut ? Thanks

Using the jitter filter by @Elusien you can make a very reasonable posterize time effect.
