I don't see how you can say that looks good. The stabilization is nonexistent, and when there is motion, it looks like a frame rate of about 15 frames/sec - very jerky. I saw some iPhone 6sPlus footage that was incredible - actually better than my very good full size camcorder. No, this is NOT good quality.

You sound upset...I bet the phone and its camera will do what the majority of users need it to do.

I shoot my video at 1080p so I don't much care for 4k but that was a little choppy FPS wise at times. Not sure if it was youtube or not causing that but I don't think youtube was the problem for all of it.

I guess since I am not a photographer, or take that many videos, that is why to me, this does not look that bad. I mean he shook the phone like a tornado was coming through. I take more pictures, so this "shaky" video doesn't bother me too much.
And to be fair, that first video was not recorded in the same manner as the 6p recording. The 6p recording was taken on the move and in some spots was purposefully being shaken around. The iPhone video was all about cinematography.
Granted, OIS is going to make a difference, and it will make for smoother shots with the iPhone, but as said before, unless the camera is the primary reason for your purchase this camera should be just fine for what it will be used for. It shouldn't be that difficult to get steady shots as long as you aren't walking/running and recording at the same time. My one M8 doesn't have ois and the video comes out fine for what I use it for.

I just call it the way I see it. Did you check out my links? I am getting this phone, but I can't say the video quality from the camera is good when it clearly is horrible.

That is true for the first link, but in the second, it was all hand held and taken while the person walked around. As far as the 6P, I am not talking about the parts where he is shaking the camera on purpose, I am talking about the parts where he is trying to hold it steady. I agree this is not a deal breaker, but call it as it is - terrible video.
So your point is what? You want to compare someone walking around with a hand held device to another on a still moving platform.

The video obviously stutters and is a bit choppy from time to time. It's ok, no need to get pissy over it. I'm going to use 1080P regardless because it won't be pushing the unit so hard I can expect decent frame rates.
Seriously, don't expect too much from 4K video recording in terms of stabilization on the 6P. I'm pretty sure EIS won't work with 4K video because there is not enough pixels in the sensor.
Basically, EIS uses pixels outside the border of the visible frame to provide a buffer for the motion and then use it to smooth the transition from frame to frame. But 4K video uses nearly all the available pixels of the sensor so there nothing left for EIS.

My point is to compare the walking around video from the N6P to the walking around video from the iPhone 6sP (second link). Here's hoping 1080p video will look better.

I never said you weren't. And I was just "calling it how I see it" when I said TO ME it does not seem that bad. But like I said, I'm not huge into taking lots of videos, especially when moving.

I wouldn't mind seeing comparable video footage recorded on the two devices from a moving vehicle. I would expect it to highlight the differences in hardware stabilization and perceived stuttering, while somewhat minimizing influence from the person recording.
Theoretically, obtaining more light at each pixel (due to 1.55um pixel size and f/2.0 aperture) helps reduce motion blur and noise on any individual frame by enabling shorter exposures (and therefore also reducing the need for stabilization), but the lack of OIS should be more prominent in the changes from one frame to the next. Judging by the posts above, that difference is evident in the linked videos.
While making several improvements to their camera, in particular the increase in resolution, Apple moved from 1.5um pixel dimensions with the 6 to 1.22um with the 6S, while keeping the f/2.2 aperture. While these changes enabled the other improvements (I suggest reading the iMore review's camera sections), it should be noted that the Nexus 6P's touted camera specs go in the other direction (i.e. larger pixels, wider aperture). Therefore the effect of OIS on the iPhone 6SP's video is more significant and necessary than it would likely be on the Nexus 6P... but there are just too many different hardware and software factors involved to know for sure. I believe the 6P and 5X use the Sony IMX377 sensor, which was designed for compact/point-and-shoot cameras, and has not been used in other smartphones. I suppose it's possible they simply weren't able to include mechanical OIS with this sensor in a form factor they deemed acceptable.
Read this excerpt from the iMore article:
The increased capacity for autofocus likely affects perceived motion blur, aiding the OIS but also making it harder to discern OIS's true impact on high-motion video. The laser autofocus on the Nexus likely means they don't need OIS to smooth things out in order to achieve predictable and accurate autofocus. And finally, as I said, those other improvements by Apple really helped offset the losses from smaller, more densely-packed pixels.
Sure, mechanical OIS is great -- but I can understand why it didn't make an appearance on the Nexus 6P. At least we have some form of software-based stabilization in the form of EIS. Software-based OIS isn't as effective at high resolutions as hardware-based OIS, which is highlighted in the difference between iPhone 6S 1080p software OIS vs iPhone 6S Plus 4k hardware OIS (see here for one example). We should be able to get a solid idea of how well the 6P's EIS performs by comparing it directly with the 5X, which doesn't have it.
I'll be content with taking the Nexus 6P's sharp 4k video frames and running stabilization in post-processing for when it really matters. Auto Awesome included stabilization, so I assume Google Photos still does, and YouTube includes stabilization and rolling shutter corrections as well. They may all use that same processing method.

The video samples you are asking to compare are far from reasonable. We have on one hand, a carefully focused and well orchestrated video sample of flowers and other detailed objects VS. Some partially coherent, Indian dude, walking around his back yard shooting water bottles. Really not a fair fight. I have no skin in the game because (short of a shark attack caught on camera) I have very little use for cell phone video anyway as I have actual equipment for that. However, I could have put several flagship video samples produced recently against that iphone (using the same rules) and made it look bad.

you cant compare the 2. 6s plus has OIS, 6p does not
OIS makes a huge difference
