iOS 11’s New HEIF/HEVC Camera Formats Will Save You 50% on Storage
At this year’s jam-packed WWDC 2017, Apple introduced two new camera formats that are included in iOS 11: HEVC and HEIF. In using the new camera formats, Apple estimates users will be able to save up to 50% on storage needs, without any loss in image quality. This becomes the perfect solution for users on lower capacity devices, that still want to take advantage of the iPhone’s great camera.
Why is Apple switching to HEVC and HEIF?
For the past few years, camera videos on iOS have been using h.264 video compression and camera photos have been regulated to JPG. As the camera improves every year, and storage capacity needs increase, and Apple pushed towards a solution with compression and quality in mind.
It should be noted that neither of these new camera formats were originally built by Apple. HEIF is a relatively new system with technical specifications having been finalized in 2015, and HEVC being around for about as long. Apple is adopting HEVC and HEIF to tap into their strengths on their own systems.
By bringing in these new camera formats, Apple can continue to improve photo and video quality, while needing nearly half of the storage. That means savings not only in photos and videos taken in the camera app, but bandwidth from live streaming services too.
By making the move to High Efficiency Video Coding (HEVC) and High Efficiency Image File Format (HEIF), Apple is getting ready for the future of media consumption and creation.
What does that mean for me?
Basically, you’ll save 50% on storage when taking photos and videos using the iOS 11 camera app.
If you’re currently running iOS 11 beta 1, you can verify this by switching between the High Efficiencyand Most Compatible formats under iOS Settings → Camera → Formats. Under the High Efficiency format, images will be saved as HEIC and movies as an HEVC .mov file. Under Most Compatible, images will be saved as JPGs and movies as an h.264 .mov file.
In testing I went out at night and took a photo and video of the New York City skyline. The outputted JPG image weighed in at 2 MB, while the HEIC image came in at 1.2 MB. Similarly, the h.264 encoded video was 61.2 MB, while the h.265 (HEVC) video was 33 MB.
