Slow Motion Video - Shot and Edited on iPhone 6 Plus.

Yes ois works in video mode but it would NOT offer a massive or big benefit. See OIS operates in the iPhone 6 by moving the sensor up/down/left/right in concert with vibrations and hand shake. This only helps when you are staying very still and for very small vibrations.
What really helps in video is digital image stabilization because it takes a frame of video, crops out parts of it and matches the frame with the next frame.
The OIS on the 6 plus isn't worth mentioning in a discussion of photography and video?

Wow. Someone can't admit when they are wrong....
Yeah and it's you. I explained it clearly. You're talking to a photo professional here, I KNOW what image stabilization is. It's NOT going to do crap for video if you're moving around, it can only stabilize small vibrations and small movements.
If you're taking a picture and staying still, it helps. If you are shooting video and standing very still and steady, it helps. If you are shooting video and moving around it's not going to do crap for you. And how could it? The sensor can move what, a millimeter in either axis? How is THAT going to compensate for someone moving more than a millimeter?
So I noticed a few people were confused by what OIS is actually doing especially during video.
Image stabilization, or IS, was designed a long time ago for photo cameras and is when motors in the lens or around the sensor move an equal amount of distance (we're talking microns - millimeters here) to compensate for an equal amount of distance moved because of camera shake (usually from someone handholding a camera who is TRYING to stay still) during longer exposures (1/30th of a second up to 2 seconds if you are really good but NOT any much slower since no one is that steady). But the point I'm trying to make is it's for SMALL movements..vibrations and things like that. It's IS going to help during video, here is an example if image stabilization with the Canon 24-105 lens:

but notice the camera man is trying to be very steady and not move much.
It's NOT going to help with sudden movements especially with things like walking. If you notice your video being smooth and steady even while movement is happening, that's digital image stabilization which is MUCH more useful for video.
Here is a picture I took last night with image stabilization on with a TWO second exposure..handheld..an eternity for photography. I was shocked I got it this stable
Here's a picture I took right after, same settings, two second exposure, handheld, but because of even the slightest movement I got this
Digital image stabilization is when a camera sensor records more resolution than you end up seeing. It does this so it can crop around the viewable portion of each frame in different places as to match up concurrent frames as best as possible. Think about if you took a 10' x 10' piece of paper and drew a 8' x 8' square near the top of the page. Then you took another piece of paper and drew an 8' x 8' square near the bottom right of the page. If you just viewed those pages one after another it would look like the square suddenly moved a big distance. But if you cut around those squares and then just showed the squares one after another they would be in the same place.
Was it really dark in there? I'm watching in 720p and it looks like this was shot with an analog camera. Colors are muted, there is splotchy noise compensation etc.
Cool tricks though. Love the slow motion shots.
Just wondering why the PQ is so muddy.
Yeah, it was dark. I also added an effect in iMovie, that's also why the colors are really desaturated and the contrast is up a bit.
Thanks
Realistically speaking, there is always the possibility for that small shake, and its going to create noise or slight instability with the video that the OIS is there to help. The fact of it is, your not going to be holding your perfectly still, and your phone's hardware OIS can do it better than you can so the video will obviously be slightly better. Now how much better that is depends, it could be very negligible in both photos and video. To me, based on photos its really a negligible difference, sure there is slightly more noise in a low light shot if you pay extra attention to it, but the focus pixels are doing more to help with the quality than the OIS if you can keep your hands steady.
Well the 6+ does have optical image stabilisation. One difference to the 6!
The fluros in the video flicker real bad! Closer angles would be good and the lighting inside not the best. My 2C worth.
been playing with this for a day I am learning fast on changing the slo motion section and trimming and what not.
I have to learn how to use iMovie, but for simplicity sake I tried to see how iMovie works and when I imported the video that is slo motion if I few it in the photos app, in iMovie is full speed is this normal?
I am using iMovie on the iPhone

I just tried it on my iPhone 6, and it was slow motion straight away.
To change the speed, tap the video in the time line, then tap the little clock dial icon, then drag the slider between the tortoise and the hare to alter the speed.
You can do multiple slow motion and normal sections of one clip, but splitting the clip and changing speed for each split
