Do any cameras other than 5D Mark III have the possibility of reduced aliasing without using in a large crop like 3x?

Yes. 5k anamorphic (crop~ x2).
For EOS M 4.5K anamorphic has a crop of ~1.18x.

Cool. How do the 1x3 and 3x1 modes compare?
1x3: no moiree.
3x1: a lot moiree.

H.264 uncropped is 3x1, correct? Is 1080 MCM 3x3? If so that could be considered a medium between 1x3 and 3x1 in aliasing and moire?

H.264 uncropped = 3x3
1080p MCM uncropped = 3x3
Anamorphic modes = 1x3
Currently not available in most builds (only available for 5D2) = 3x1
Crop modes = 1x1

No. Reading all lines -> no moiree. Reading each 3rd line -> moiree.

Not when rewired into mv1080p on eosm(uncropped that is). Then it´s regular mv1080p 3x3  :-*.

Officially Movie crop mode meant to give x3 crop in H.264 video which is 1:1, on EOS M we are patching MCM 1:1 to mv1080p 3x3 to get proper un-stretched preview, EOS M stays at mv720p when Idle (when not recording H.264), so we need to patch it to mv1080p to be able to record RAW video in 3x3 mv1080, on other cameras like 650D/700D MCM is 1:1, which is cropped :P
