The iPhone has one of the best smartphone cameras, but you cannot record
videos in 4K according to Apple. But App developers has found out that
the iPhone from version 5s onwards can play back as well as record 4K
videos. Depending on the application, the videos are recorded in a
maximum resolution of 3264 x 2448 pixels. The maximum number of images
per second (fps) is 30. You will need a memory of 50 MB for every
second.
This makes it around 3 GB for one minute. Your clips
will be stored in the M-JPEG or H.264 format. The apps, Ultrakam 4K or
ProCam2, required for this, can be bought for around RM36 in the App
Store. ProCam 2 is indeed cheaper at first glance but you have to pay
extra for activating the 4K option.
At the end, both apps cost the same. Unfortunately, storage is an issue
for smartphones as mainly it is very expensive, in case of Apple. Hence,
do think carefully as to which video you wish to keep in high
resolution else you will be left hanging with storage problems quickly.
It is also recommended that you do not save the 4K videos on the
smartphone but backup it to a computer instead.
