Have you looked into the signalstats filter? It is often used in the
QCTools application in order to find glitches in digitised/migrated
analogue/digital videotapes.
It looks like your example image might have a spike in UV values and maybe
even a spike in saturation. It could be worth analysing a glitchy video in
QCTools,figuring out which stats seem to be triggered by the glitches you
encounter,then add the appropriate calls to your API usage. The qct-parse
python tool tries something somewhat similar

Best,

Kieran.
