What are these flashing horizontal artifacts from an old LaserDisc rip.

I've included a clip. Can these be filtered? I'm having trouble finding details on what these are. They look like artifacts from a dirty VHS head but this is from a LaserDisc. Anyway help or direction would be greatly appreciated.

Dropouts? You can remove most of them with AviSynth. You can also clean up the crude frame rate conversion and the mediocre deinterlacing.

LWLibavVideoSource("Night Life (1989) LD.mkv", cache=false, prefer_hw=2) 

RemoveDirtMC(30, false) # reduce droputs
TDecimate(Cycle=6, CycleR=1) # remove duplicate frames
QTGMC(InputType=2) # stabilized flickering edges

Thank you! RemoveDirtMC has a lot of specific filter dependencies is there an easy way to download these all at once? I'm having a hard time finding some of the specific versions of filters it's asking for.

Not that I know of. You might try using Spotless() instead of RemoveDirtMC(). But it probably has many of the same dependencies. Also, there are several variations of RemoveDirtMC(). You may have to change the parameters.
