I have a simple trick to at least mitigate the effects of morié. I understand that sometimes reshooting isn’t an option. I have used this with positive results on shirts with lines.
In After effects simply add 2 adjustment layers above your problem footage. Add the “median” effect to each one. Set the blend mode of one to “color” and the other to “luminosity.” Play around with your radius settings on the effect for each one.
Depending on the type of morie that’s happening, you may not need one or the other layers, but then again you could need both. Massage the numbers until your morié is lessened.
Unfortunately it probably won’t go away entirely and you’ll still hate the footage, but if you do your A/B comparisions, you most likely will like your “B” results better than the original.
If you’re problem is in an isolated part of the shot (e.g. a person’s shirt), then you’ll need to isolate the problem area (I use rotobrush to quickly fix shirts with good skin contrast) and apply the Median effected adjustment layer(s) to JUST the problem area.
And, with all roto, have fun!
