1D Mk IV can do white walls?

Curb your enthusiasm!

That's a shame. It looks like we'll be waiting a while longer yet for a true 5D killer from Canon. Surely the option of a heavier AA filter over the sensor would have sorted this out?

Yes, while destroying the fine resolution of the still-camera side.

It's a still camera first and foremost, the AA filter is optimized for stills, and that's what lets the aliasing through, causing issues like this.
 
Any idea it would be 720p? At 720p I can easily show such moire with most current DSLRs. Hardly that bad with 1080p.
 
That's a bit scary. I'm curious to know if the aliasing/moire ends up WORSE than the 7D... Its a bigger sensor with fewer megapixels- theoretically, this would be better for less moire, but maybe this doesn't influence video at all- or it does, in a BAD way...

Unfortunately, I don't see Barry forking out 5k for this camera to put it in his super dupper charts, so either someone takes the plunge and posts the results, or the risk factor on my next purchase just raised 100%...
 
it makes me think...somebody somewhere is gonna come out with a AA plugin very soon to help compensate for this... the foundry already has a rolling shutter plugin, why not a AA plugin? if nobody is working on it, SOMEBODY SHOULD!
 
Before I had the diffusion filter I tried the AA filter for Final Cut Pro and it had no affect on aliasing, so I am curious to hear that poster's methods. I can add his technique to mine and create an all encompassing filter AND software fix for aliasing & moire.

In this instance I simple blurred the chroma a little.

LMFAO. And that simple technique made the still image completely acceptable without horrid oversharpening in camera or post or anything else. For future reference: where, what, how?

This is probably the most simple and efficient quick cure I've seen, man. Good job as usual, Lee.
 
For a still. But how does it affect motion? Does the underlying alias pattern still exhibit itself, just without the color effect?

Ah right right. Same thing with denoising. Might look good for a still but a lot of denoising turns imagery to oil paint plastic mess in motion.

Gotta try it.
 
Blurring chroma will work for "rainbows", but not for the "line twittering" from aliasing (e.g. the opening sequence when the camera pans over the stripped shirt)
