But from the 1dX manual data-rates, it looks like it uses the same codec...

It's hard to tell from the video. You can see that the light keeps changing in the background(like the sun going behind clouds), and it appears much brighter in the 5diii footage, so it's hard to attribute it all to DR.

If you look at the escalator in the background, you can see more detail with the 1DX.

Awful test. It looks lke the shooter used the same lens but slightly different focal lengths, plus the tripod has moved in the second part (more to the right). Put two fingers on the escalators then fast forward to the 1DX test, you'll see the composition change a lot. Also count the window squares to the right - it'll become readily apparent.

A prime lens would have been a much better choice (e.g. a 50mm f/1.4 even @ f2,8) for a HD video test, rather than using a standard zoom shot wide open. Neither of these videos are at all sharp.

Also the colour varies, for instance, the 5D3 appears much more saturated (look at the red roof/top on model building down to the right, lower level).

The 1DX does seem to show a bit more detail - look at the window frames on the far wall (you can see most of the vertical & horizontal lines, not so on the 5D3), but that could be because of different camera position + it seems that the ambient light was brighter on the first test.

1/25 shooting night also challenging, because it is not a pervert. . . (; ^ _ ^ A . I need a camera that is a pervert for very low light.

It is possible that the focus was not spot on during the test shot with the 5D3. What would you define as true 1080p resolution? 1920x1080 or 1920x1080? LOL get it?...  ;)

What would I class as 1080? 1920x1080 in all 3 colours. Not just 1080 bayer filter lines.

Wow, I get 50 times sharper video with my 5d3, is it Vimeo that is to blame with way to hard compression?

Yes, the 1DX is better than the 5D3…but..why are we surprised?
It's got everything in it better…
But we mustn't forget, it's also double the price! Surely it had to be better than the 5d3..

Am I the only one that doesn't see much of a difference?  Maybe if they were side by side it would be easier, but I even downloaded the original and I just don't really see it.  The 1DX may have a slight edge in terms of detail but nothing that couldn't be achieved with slight sharpening in post on the 5D3. 

I wish they had done a tighter shot in a room with artificial lighting, the changes in natural light in there seems like it could really skew the results.

Yes, you do lose some sharpness to and there are slight changes in color on Vimeo (it usually brings up the reds).

The focal length looks the same, I'm pretty sure it's just the framing that's different.  But I agree with everything else, they should have done this in a controlled environment and used a tighter lens (DSLRs aren't known for detail on wide angle shots), I'd be curious to see the results of that.

I'm not weeping into my beer for getting the 5d3 instead given this result. Better resolution tests are needed.
