720P aliasing / moire work arounds?

I've been aware of moire and aliasing problems on SLRs since I started using these cameras for video, but had never experienced any serious problems until yesterday. I put my 60D into 720p 60fps for over-crank in a woodland scene. My god, the aliasing: hellish, shoot-ruining stuff, most noticeable on the leaf-littered forest floor where there was fine detail. Thank god it was for fun, and not for a job.

So, I'm canvassing for experiences and opinions of what people use to get round the problems created by line-skipping in 720p; I want to be able to get slow mo from my 60d. I'm thinking primarily of workflow and software fixes (I already know what I should be with shot composition to control aliasing and moire).

Is there a solution with magic lantern?
Shoot 24/25/30fps 1080P ( at 100th of a sec) and slow down in post? (workflow solution needed here for large batches)
Plugins? Are any of these any good or will they just soften the detail?

Any other solutions that don't involve using a different camera?

Thanks in advance.

Not really, I had a Canon T2i and after shooting several video jobs with it and numerous
client complaints about the image quality of some shots, I sold it and
now shoot with GH2 at 66Mbits. The good thing was that my Canon
stuff was new enough that I did not lose much money when I sold it.
No more client complaints = happy customers and more work.:2vrolijk_08:
 
DOF , Turn sharpness and contrast down in camera. Also be careful how you frame your shots, if you have a good eye you can catch a good angle to help eliminate with these problems.
Also believe it or not having an actually lens that is not sharp and a little soft helps with this a lot.
 
i would second the "sell the t2i and get the gh2" motion.

-Sharper

-least amount of "dslr" moire, aliasing, rolling shutter.

-clean hdmi out......only dslr to do this right now

-native ability for timelapse

-720 60p is better than any of the canons 1080


all i can think of for now...lol.

That said i own the t2i and love it, but first chance i get am gonna couple it with the gh2.
gh2 vs 60d is like comparing BMW and Honda

60d is a good lil cam but has probably the worst aliasing/moire.
 
If you really need to shoot slow motion detail with a Canon Digic4 camera, you might be better off shooting 1080p and using Twixtor to slow it down in post.
