moirre

[calhoontuna]

Yesturday had to shoot someone with thin stripped shirt. Got the dreaded moirre buzzing phenomonon.

Are there any tricks to mitigate this after the fact?

Rit fabric dye.

You can blur the image, but you'll probably loose other details you want to keep.

Awww, that's just mean ... :p

Sometimes a gentle blur helps. You could also try de-interlacing the clip to see if that helps.

My first response upon first reading this was... Here's how to fix it... re-shoot.... You can try a slight blur.. and a floating matte
Keep the face in focus and blur the shirt..


I used to teach at a university where they had a communications class.. on campus video etc.... I was always the first, and the last faculty member they had in class. The first time I was super helpful... wired myself, calmed the talent... pointed out issues, etc...

The last time I wore the moirre shirt.. pulled off the mike.. was the worst jerk ever... as bad an interview as possible. just to prepare the students

Maybe I need to make better use of smileys - it sounded light-hearted in my head :-)

Seriously though, if at all possible, a re-shoot is probably the most practical way to deal with the problem well.

Thinking more on the blur approach, it would be worth fidgeting with it a bit to see how much it helps - and croping and softening the edges of a blurred layer, so most of the blurring is constrained to the shirt, if the shirt isn't moving around too much. Not having seen the clip though, I expect that enough blur to really kill the moire is going to attract attention at seams, buttons and the collar.

Yeah, I knew you were kidding, no worries. :)

Sometimes it only takes a very little blur to make a big difference. It depends on the size of the problem pattern. (Other times, before it makes much difference you may look like the scene was shot 'in foggy olde London towne.'

As billmi mentioned.. blur a layer.. and use a traveling matte to blur the shirt a bit, and leave the face unblured.

Of course, SE doesn't directly provide a matte feature, but you might get somewhere with cropping and feathering a duplicate layer.

Thanks guys.

Blur did mitigate quite a bit. Think it will work.

Bobssoftfx for that matte and blue combo. Well worth the bucks.
