Jerky footage after restoration attempt...

Thick borders give filters like SmoothLevels a hard time--or, they give me a hard time fiddling with the code. They'll have to come off and/or be replaced later anyway, they won't be black after other corrections. I also temporarily remove them anyway when working on color: they're distracting.

Also: if I left the clip cropped, I had serious chroma disturbances with IVTC, and also with QTGMC earlier. Those two guys didn't like my crop, I guess.

Chroma distubance might be because of mod4 rules for height with interlaced video. If you IVTC then crop, mod2 is ok . Maybe some of the values you used earlier violated that.

If that's the case, even adding a few pixels for borders to satisfy crop restrictions (instead of the adding same values back), will make processing go much faster with MCTD and various slow filters

I figured a "mod" factor was afoot. Thanks for the tip.
