That IR video was horrible to watch.

Why? It's pretty cool that you can easily shoot IR by just taking off the IR cut filter... More pro cameras should offer that. Might even mean there is room for a market of 3rd party behind the lens filters as well?

IR is more relevant (as with 5000 ISO) for nature docs, which I think is a market Panasonic is pursuing actively.
 
But the DR in that video is very bad. High lights are clipping badly and abruptly.

where? Slightly on the edges of the sun in a couple early clips... it seemed nice to me elsewhere, but maybe I don't have the eye for it. At what times/clips and what is an example of a better roll off or look?
I thought it all looked quite nice.

Where? I'm not seeing it. Maybe check your monitor? Also keep in mind that soft clip can be affected in most digital cinema cameras by shooting at a lower ISO/ASA. I would say the colors and DR in that video isn't the best I've ever seen but quite pleasing overall with nothing bad except a weird green tint in the tiger shots at the end. Certainly nothing there to indicate low DR and clippy highlights ala CION/BMPC...
 
I watched it in 2 different monitors and it's clipping. White garments, hair high lights and all sorts of high lights clipping there.
 
Here's Charles' test images, the Arri with it's burnt in Rec709 LUT and the Varicam put through ACES in Resolve (with no adjustments, just the Varicam35 IDT and the Rec709 ODT):

The colours look fine on the Varicam, however I find that moire REALLY disconcerting. I've been burnt by moire too many damn times already (plus that isn't the sort of fabric you'd expect to have issues with).

Was the Varicam footage shot at 4K DCI ?

...It may not be relevant, but the only way I can be pretty much guaranteed of no moire with my GH4 is to shoot 4K DCI. With one GH4 project I had a tiny bit of moire popping up on a doctor's shirt collar when shooting at 4K UHD, and I know that the GH4 1080p modes are much more prone to showing moire.

So I'm wondering if moire is more likely to show up with the Varicam using specific formats. ( also, is there any difference when shooting with the V LT instead of the V 35 camera ? )

One last thing: Is the moire still visible when viewed at 1:1 pixel resolution ? I've seen lots of "false" moire when viewing 4K footage at lower resolutions, so the method you use for down-rezzing your 4K footage makes a big difference in keeping moire out of the picture.

4K AVC-intra 444.

I haven't shot DCI. But this mirrors my tests--the same image shot at 1080 has notably more moire than at 4K. And the LT has same sensor and processing at V35, so no reason to assume it would be different.

Haven't done this.

Still there at 1:1

I find it funny how ya'll are zooming in on her breasts without even realizing it.

Video Guy: "We're looking at moire! I swear!"

Woman: "*Slap*"
 
Hmmm... When viewed at full resolution the AMIRA is also showing a tiny bit of moire...

This really looks like a non-issue to me. You just have to be careful how you handle your footage, especially when down-rezzing to a smaller format.

Where? Do you mean those lines curving downwards between her breasts? That's the weave of the fabric itself (you can see it in the Varicam shots too).

It moves and shimmers when I loop the AMIRA footage, so it's definitely NOT the weave of the fabric.
 
When I loop the Varicam footage I see the same movement and shimmering on the lower section of the woman's shirt, but NOT where I'm seeing the movement and shimmering with the AMIRA footage, so to me it looks like they BOTH have a minor moire issue but with different sections of her shirt.

I am curious if switching to 4K DCI will completely get rid of all moire. ( like it does with 4K on the GH4 camera )

I'm not sure we're watching the same videos then. I've tried looping the Amira footage, but the only thing I can see moving is the rise and fall of her chest and a bit of noise dancing about, I can't spot any moire patterns on the Amira footage.
