I thought "severely corrupted" was enough. Yes, corrupted compared to

My command was:

ffmpeg -i "Zone Plate 85L.mov" -vf yadif=mode=1 -t 00:00:00.12 -f image2

I do not believe I am allowed to let that test file out, but I'll see if
I can make something similar that demonstrates the corruption (assuming
I see the corruption from your tree).
