How to Get Rid of Minor Aliasing and Moiré Problems in DSLR Footage

Aliasing and Moiré. The bane of many HDSLR shooters' existence. Many have tried and failed to defeat the jaggies and discoloration that reveal the ugly, line-skipping truth about our DSLRs. But now Jorgen Escher has released a Final Cut Pro plugin that can defeat some of these problems. While you shouldn't expect Jorgen's plugin to cure the most serious of aliasing issues, he's come up with a post-production method that works by defining the problem areas and applying chroma blur. Here's the before/after video:

In Jorgen's words, here's when one should use the filter:

To cut a long story short… If…

  • your footage is spoiled by red/blue streaks ad pixels in natural patterns and materials such as hair, grass, leaves and water…
  • putting a soft filter on the lens did not help…
  • you were not aware of it during shooting (not visible on LCD)…
  • you are using a lens that is much too sharp…
  • grass, leaves, gravel, sand or turf is swarmed with red and yellow worms (could be LSD though) …
  • you’re ready to smash your DSLR camera into the next tree…

Then this plugin is something you’ll love!

Jorgen notes that "This is NOT a blur filter. It will not soften your image. It transforms the colorspace to YCbCr and breaks it up into components, further only affecting the “CB and CR” channels." While it will work on hair and fine moire problems, don't expect it to cure serious cases of the jaggies. If you download the filter and put it to good use, a $10 donation is suggested.

Just tried it on some footage. Worked very well at eliminating the ugly purple/red/blue stuff on the edges of fine details.

Definitely will keep this plugin. Nice find.

Looks rad! I'm keeping my fingers crossed for a Premiere CS5 version...I'd pay $50 to $100 for that!

I would like to see if it can fix Aliasing and Moiré on fabrics! Any examples available for that?

it does the job on chromatic aberrations...but sorry the moire it's getting any better... it just change the defect type to another... so for me...it's not worthy to remove a defect with another defect

I have found a VirtualDub filter that works very well. http://freevcr.ifrance.com/virtualdub/cnr-en.html

It reduced my moire problems significantly. Just download the filter and paste it in the plugins folder.
