Why is the last frame of a Live Photo so much brighter than the other frames?

When playing back a Live Photo, why does the last frame display as being so much brighter than all of the frames before it?

Thanks

As I understand it, a Live Photo is a hybrid of video and a photo. The video is probably much lower resolution than the core "still photo" so when you see the final photo, you are seeing the high resolution still instead of a lower resolution video frames. It's not that it's necessarily brighter but that there is much more detail to see. If you think of pixels as tiny little lightbulbs to turn off or off, more bulbs are available at megapixel resolution for stills vs. even 4K or 1080p video frame resolution for video (I don't know if Live Photos uses 1080p or 4K for the video portion).

You can likely see the same effect by taking a still photo of something and then switching to video and taking some video of the same thing. Then compare the "brightness" of both.

And photos are instantly improved by the software, that's another explanation if there is some color shift going on.

I don’t see any difference in frame brightness on my own Live Photos. My understanding is that the video is 1.5 seconds on either side of the photo. So the photo would be in the middle rather than at the end.

Or OP means the still photo that the Live Photo arrives at, "the last frame" in the animation.
