Looking to reduce Moire effect on video

[Steve Roberts]

Is the footage properly interpeted by AE?

If so, then all I can think of would be to apply a 1-pixel (or less) blur to the footage in AE.

Do you have a screen capture of an offending frame?

Sometimes the moiré only occurs in the color-channels (green/purple moirés)
Check if that’s the case using the channelcombiner rgb->yuv and check the first (R) channel.
Sometimes you need very aggressive medians or blurs to get rid of those, but you can recombine the original Luminance back in using a layer-mode of luminosity.

I’ve got a more long-winded method for moire reduction, but it does offer a lot of flexibility.

First grab the Animation Presets at http://www.curiousturtle.com/training/presets/moire reduction.zip and install them into your Presets folder. Now follow these instructions (told you it was more long-winded).

i) Duplicate your footage twice, so you have three indentical layers.

ii) Apply the appropriate preset to each layer (top goes to the top layer, middle to middle etc)

iii) Precompose the top layer(select it and Cmd-Shift-C or Ctrl-Shift-C). Select “Move All Atributes…” when you precomp. Now turn off visibility on it.

iv) Go to the middle layer. On the “Reduce Y Moire” effect, twirl down Second Source and select your pre-comp layer. You should immediately see something happen.

v) You might want to change the Blending Mode on this effect to Soft Light (or another) and reduce or increase the Opacity.

vi) When you’re happy with this, change the layer’s overall blending mode (on the timeline) to Luminosity. You can now play with the Levels command to get your Brightness/Contrast right.

vii) Finally, go to the bottom layerand adjust the vlaues in the Channel Blur filter. Only touch the Green & Blue values.

And that’s you done. Not bad, eh? :o)

Good luck with your project,
Ben

Thank your for your help but a decision was made to do a re-shoot. I will definitely keep those instructions for future reference.

Hi Ben – I know your post is dated, but I, too, have moire problems and was planning to try your solution – but the link was dead. Any chance it can be revived?

Many thanks…
