Until now, we have been accustomed to being close to each time one software maker or developer promises performance after an update, it actually means a smaller space on the device and even complicate the system.
iOS 11 seems to no longer follow this "rule," and the owners of the iPhone si iPad will no longer have the stress of the space occupied on the device with pictures and movies.
New technology HEVC (H.265) implemented by Apple pe iOS 11 will allow better compression a File photo si video caught with apiculture Camera, and for photo the format will also be entered HEIF – High Efficiency Image File Format.
What is High Efficiency Video Coding (HEVC)
It is not new. It is used by Apple from 2015 to save bandwidth (bandwidth) in FaceTime video calls. So using the codec HEVC are possible video calls in HD format with low internet traffic. Very useful when we are connected to a mobile network 4G cu limited traffic.
The format was also used by Netflix and Amazon Instant Video, but only for non-mobile devices.
What is High Efficiency Image Format (HEIF)
High Efficiency Image Format (HEIF) is the new format developed by Apple for pictures / photos. If up until now we were used to it picture to be in .JPG format (which has become synonymous with the digital image), iPhone and iPad users will get to know .heic. This new format will also be used by HEVC to encode images from video recordings. They will be half the size of JPG and H.264, while maintaining image quality. Normally, encoding and decoding will be much faster than JPG.
Therefore. the biggest advantage of the new HEIF format is saving the picture and video space on iPhones and iPads, while preserving image quality.
For iPhone users who need to view photos on Windows, iOS 11 will automatically convert from .heic to .JPG when exported to Windows PC.
