Video Editing
Put this one in the category of wondering what took Apple so long, but you’ll finally be able to perform basic video edits directly within the iOS 13 Photos app.
In the past, even doing something as simple as rotating a video — a need that we’re sure everyone has encountered — required a complicated trip into another app like iMovie. With iOS 13, you’ll finally be able to do this rotation much more easily. There are also options here for cropping and trimming videos, resaving them over the original rather than creating a second copy.
Almost all of the other tools that work on photos can also be used with videos now too, including things like lighting, exposure, and auto-enhancements.
