The Why video does NOT have very nice resolution

To my eyes it has better resolution than my 5D. You can tell by looking at the beard, skin wrinkles, hair and ground with rocks... Resolution is more than acceptable in this video.

Regarding the moire for Why, I'm not sure, they shot a lot of wide open shots that would hide aliasing/moire and they tend to appear in more man made materials rather than in nature where you don't have things like patterns and parallel lines so much.

There's so many camera angles to look at in the "WHY" video including many wide shots. There's cars, kayak, road signs, metal watches, many fabrics, hairs etc.. I can't see any aliasing or moire. A lot of shots in this video would have looked terrible on 5D and they look incredible here.
