She doesn't get darker as she passes by the pillars except at the end. She also has fill light exclusively on her while the floor and walls don't seem to catch any of that. So I'm guessing GH4 with green screen background.

I'd say GH4, the DOF is really deep and the girl looks a little oversharpened...

Doubt a tilt shift would produce such a fake looking blur. The DR looks alright so i don't think its an iphone. Doubt its an a7s due to the deep dof. So I'd say GH4.

iPhone with blur filter?
 
The Depth of Field is enormous. From the front to the back of the hallway everything is in focus... the blur on the sides looks artificial, ugly imo. Could be a tilt lens, but looks more like a fake blur instead of bokeh - correct me if I'm wrong though.

A7S at 120fps? :)

don't know and don't care. I think I'll loop this the rest of the day before I make my guess. 

Doesn't make sense to me; that is, blur doesn't seem to be from lens but in post.  When she's walking, a doorway far behind her in focus, which wouldn't make sense if blur/focus is all optical.  Or maybe an optical filter for blur?  
 
In any case, should be a shot any of those cameras can do.

Love it! No idea what camera but since I own a GH4 I hope it's that.

Fs700?

Quick Review A7S vs GH4
 
Where the  GH4 is better:
Build quality Viewfinder Flip out screen User interface (by a mile) Battery life (by a mile) Color science Skin tones Rolling shutter (by quite a bit) Detail (internal 4K and 4K to HD) Noise grain (mostly pleasing monochromatic) Built-in flash for stills When lens size is included, a much smaller package Can shoot best quality on < 64GB Class 10 UHS-1 cards (A7S requires >=64GB cards for XAVC-S) Price Where the A7S is better:
Low light (it's very good however the noise grain is colored and multi-spectral; not as pleasing as GH4's mostly monochromatic fine-grain noise) Shallow DOF (add a SpeedBooster/focal-reducer to the GH4 and this isn't much of an advantage) Audio (no buzz; not tested thoroughly yet though) If a 5D3/full-frame owner: can use existing lenses with a non-focal-reducer adapter (with similar DOF) Super 35 mode allows use of many NEX lenses (some aliasing) Auto ISO After having worked with 5D3 14-bit RAW and RED RAW, where the unmodified RAW looks pretty good straight from the camera, Slog2, Cinegammas, Cine-D/V, etc., start looking like gimmicks. None of those gamma curves are providing a real increase in dynamic range. In certain cases they may provide more information for 8-bit compression, however they can be tricky to use and must be exposed carefully. I've had the best luck shooting Natural with the GH4 (and no crazy curves), though iDynamic is helpful sometimes (appears to be local pixel group based processing vs. a simple curve. The A7S has a similar feature (disabled if any picture profile or effect is active, though)).
 
Rolling shutter is very challenging on the A7S in full frame mode (worse than the 5D3): not very usable for handheld without a lens with IS and/or a solid rig. The A7S menu and button system is a mess. The FS700 has a better design! (many folks find the FS700 non-intuitive to use).
 
Both cameras have aliasing and moire in slow motion. Perhaps similar to the FS700 in 240fps mode (not as bad as FS700 480+fps modes). I haven't done a direct comparison, however the FS700 120fps and less slow motion is better than the GH4 and A7S (all slow motion modes).
 
While the A7S isn't quite a one-trick-pony (low light), the GH4 is a much better all around camera. I haven't had the A7S as long as the GH4, so there may be other elements that make the A7S more compelling, yet to be discovered.

In simple terms, it's possible to get decent reconstruction using statistical analysis (vs. simpler methods such as bilinear interpolation (which is easy to code and is very fast)). If one starts with super high resolution, such as with RED (say 5K) and are targeting 2K, the quality of the debayer step is less important than say 5D3 RAW 2K debayered to 2K (ACR and Resolve do a much better job than the on-camera hardware+firmware: much sharper and more detailed images when debayered in post). Interestingly , RED Epic at 5K debayered (and without any sharpening) looks softer and less detailed than GH4 4K H.264 compressed (100Mbps):

Lol- there won't be any cats, ducks, buildings, matches, cigars, cigarettes, fireflies, smoked fish, day-for-night, skewed trains or test charts.

A lot of folks are still on the fence. After more real-world reviews, making the decision will be easier. For our testing, if the A7S can replace 5D3 RAW for most video uses, it'll be a keeper. The 5D3 will be way better for stills unless we invest in some native lenses. We will compare it to the 5D3 (RAW), GH4, FS700, and even the iPhone 5S (has really good color science and looks great in bright light). Not sure if we'll have time for a video review, but will report what we find.

Seems like an ideal pair with a set of Rokinon/Samyang manual primes.

If you need slomo (up to 240fps), the FS700 is good for what it costs. You might look into renting an Odyssey 7Q to get you ProRes or RAW with the FS700 (the 7Q will also help with critical focus). Also consider a RED Scarlet. Many rental houses are upgrading to the Dragon sensor and non-upgraded Scarlet's might be a lot cheaper now (up to 120fps slomo).
 
I have found it's best to set up the FS700's color profile(s) to do close to what you want for the final output. It's reasonably gradable, however when shooting people/skintones, it's best to get the color profiles as accurate as possible and to expose and set WB precisely so that skintones look their best.

Some 1:1 bits of  1080p clips made from a GH4 4K. test clip dowscaled to 1080p on export. The original clip comes from the other thread, and was heavily banded on purpose.
 
We can safely say working at 4K but exporting at 1080 is good!
 
Transcoding to 1080p at the start is just shooting yourself in the balls, but less sensible.
 

These are my favs!!
 

they must be the ones that shot the winnebago man... now this is a major client,
