Live Photos Called 'Best New Feature,' Composed of Separate JPG and MOV Files

When they first announced the live photos thing it reminded me of Data's hologram/picture thing of Tasha Yar, where its kind of like a picture but there's a few seconds of movement.
Sounds like a fun feature, not something I would trade my 6 in for right away for a 6s, but something I would definately use.

The recording begins as soon as you enter the camera app, i.e. anything that is displayed on the screen as a preview is temporarily stored until it becomes 1.5 seconds old, then gets dropped. Once you hit the button it takes the full picture, retains the buffer, and records an additional 1.5 seconds of video. As stated above this is how most DVRs work, which is why you can hit record after starting to watch a show.
- The jpeg in this 'Live Picture' is stored at its full 12 MP resolution (which is roughly the resolution of 4K video, different aspect ratio though), the video data is stored only at something similar to 720p video. The precise ratio between the jpeg and mov resolutions is 17x. That alone cuts down that factor of 45 to about 2.6x.
- Additionally, video compression is far more effective than compressing each frame as a jpeg. It essentially only needs to store the changes from frame to frame (after storing the initial frame), if some pixels don't change or change only little that saves a lot of space (a static background and a static camera thus can reduce the size of movie file a lot). And there are many more compression tactics that rely like JPEG compression(JPEG compression records the colour information in a lower resolution than the brightness information) on the human inability to notice certain things (like reducing the bit depth of colour).
I don't believe so.
Turn on live photos mode once. Then the phone is always recording the loop without any user action. When you take a photo in the usual manner, it is stored as both the "live" and "still" images.
If you read you will see that they can, but, on specific devices with specific OS's. Again OS X 10.11.x El Capital, iOS 9 and WatchOS 2.
OS X is on a computer, iOS can be on iPad/iPod touch (not sure yet how it would work on the iPad/iPod touch but they do show an iPad in the poster) and WatchOS is the Apple Watch.. so 2 out of 3 are not iPhones.
Gif animations that come with a still image that has a resolution that is 17x higher than the gif/video resolution. Plus audio, as others have already mentioned.
I don't see Touch ID or Force Touch as gimmicks. Both are hardware-based features which took a lot of time to develop, and make using the device quicker/easier.
Live Photos, however, is more on the software side, and I don't see it having as much of an impact as the two hardware features mentioned above. Simply a short video with a photo thumbnail, presented in a stylish manor.
What is size of a three-second movie file [shot at the standard resolution setting of 1080p and 30 fps] compared to these 'Life Images'?

Who care about how a photo is stored ?
Actually not ... Totally different from gif animations...
You just did it...
Joanna Stern is the most annoying "tech reviewer" ever. She really thinks she is funny, but, she's not. She tries, and fails. I wish WSJ would get someone else. She's just awful. I can't watch her stuff anymore. She's just too annoying.
There isn't anything hardware-wise keeping previous gens from doing it, is there?
Right but that still doesn't detract that at the time, many people saw fingerprint scanning as a gimmick.
Yes, Htc had it ... and nobody cared.
I'm sure that Apple 's implementation will be welcomed and enjoyed by customers, as usual.
Well then, it would be no problem proving it, right?
(By the way, one manufacturer having something that's sort-of but not really it doesn't equate to 'all of Android' having it. It means that ONE manufacturer had a moving picture concept, not Android. And the HTC one version is not the same)
Jpeg files sizes are usually 25% of the megapixel size. An 8MP iPhone photos were usually ~2MB. 6S photos should be around 3MB's.
Just as many people now see Force Touch as a gimmick. I can tell you that I didn't see Touch ID as a gimmick, don't see Force Touch as a gimmick, but I do consider Live Photos to be one to some extent. It may still catch on eventually, as many features that Apple push out do.
Every JPEG from any camera is compressed but that compression can be varied over a wide range. A factor of 20 in the jpeg file size between the minimum and maximum compression level is easily possible. An uncompressed 8-bit 12 MP image has a file size of 36 MB, the size of 12 MP JPEGs might vary between 20 and less than one 1 MB.
The size of a compressed image can also vary significantly how uniform the image content is. A jpeg of a perfectly uniform colour (which isn't really possible to get from a camera because there is always some variation due to noise) of a 12 MP image can be compressed down to 100 KB (most of which is overhead probably).
