Effectivly avoiding moire

Other than a VAF filter, or lowering the sharpness is camera, is there another effective way to avoid bad moire in your footage?

I understand the science behind it and why this happens in DSLR, but I still can't determine a good workaround. And it's always the footage where you didnt realize it was there beforehand, that you see it.

I recently shot Cinestyle, and I wonder if THAT may have been the cause and I would have been better shooting a standard picture style on my Canon t2i.

I also looked through the forums and saw other suggestions such as blurring or using a channel effect in post processing. Am I overlooking something, or have I covered all the bases and just have to pay attention to what I shoot more effectively?

Here's a very good article on why moire happens and how to lessen the odds of it happening:

Dave - I got rid of moire by selling my T2i and buying a Panasonic GH2 a couple of years ago.

Since then, I have upgraded to the Panasonic GH3. Still zero moire (except in one specific mode - 72mpbs ALL-I).

When I switched to Panasonic, it was the only moire-free large sensor option. Today, there are two large sensor interchangeable lens cameras below $1000 that are resistant to moire. Sadly, neither of them are Canons.

1. Panasonic G6
2. Nikon D5200

Above $1000, there are a few more choices:

1. Canon 5D Mark III
2. Nikon D7100
3. Panasonic GH3

In my view, the dirty little secret of moire is that it is a technical challenge that can be overcome - but some camera manufacturers seem to have made a conscious decision not to solve it in their low-end cameras and large sensor camcorders (e.g. Canon and Sony).

Yes, you can buy filters or use shot selection to avoid the problem - but I'd rather shoot with a camera that is not susceptible to it in the first place.

Best of luck in overcoming this challenge,

Bill,

Thanks for the response. I may jump ship. I've been looking at the GH2 for years now. And I'm not that much invested in glass. I do like Magic Lantern though and all it offers.

Anyway, thanks again. That was very well laid out and gave me a lot to consider. It's a matter of do I get the G6 or do I have and get either the GH6 or the MarkIII.

We'll see. I appreciate the input immensely.

Glad I could help, Dave. If you do decide to jump ship, and it fits your budget, I recommend the $1098 GH3.

The headphone jack, moire-free 50mbps recording and 1080/60p frame rate make it a great value for the money.

Its only real shortcomings, in my view, are its lack of focus peaking and RAW.

So I ordered a Blackmagic Pocket Cinema Camera for peaking and RAW - and still spent less for the two cameras together than the price of a single 5D Mark III :)

Good luck with your decision!

I have recently tried this moire removal add-on for Neat Video and it worked wonders for me.
