The Sony Xperia XZ Premium features a 960 frames-per-second Super slow-motion video recording at 720p HD resolution. This is the first phone in the world to offer this feature. Just for comparison, most current phones that offer a slow-mo video recording features hax max video recording frame rate of 240fps, which is more than 4 times slower than what the Sony Xperia XZ Premium offers.
Shooting at 960fps allows you to enjoy and observe every tiny bit of movement. This is a superb feature and a big advantage that the Xperia XZ has over its competitors. This allows users to become really creative with their camera.
While recording the video, you can always switch from real-time recording (1x speed) to the slow-motion and back, so you can create smoother in-out transitions between the important parts of the video that you want to be shot in slow-motion. Because 960fps plays very slowly, you don't want to burden your viewer seeing a long video all in slow-motion. So it's great to have this control over the video recording. Here, take a look how the video was shot in 1x speed, and only when the guy touches the water balloon with the pin,the camera start recording in slow-motion, pretty cool stuff.
This is just one example showcasing the 960 fps capability taken by GSMArena. There are plenty more available on YouTube. I'm sure that soon we are going to see thousands of amazing artistic videos that take advantage of this super slow-motion video recording feature. I think it would be awesome to shoot insects, animals and birds, showing how they move in slow-motion, especially those fast flying birds like the hummingbird that moves its wings very fast that it seems like it doesn't have ones.
You can of course use it to shoot motorcycle racing events and capture the motorcycle getting into the turn slowly or even better to shoot Motocross, dirt-bike or off-road racing. You can experiment with lots of stuff like see how things break in slow motion and how their parts fly all over the place. I'm sure you'll come up with some better ideas, but you get the point.
