Will the new HEVC and HEIF formats work in older versions of macOS and iOS?

“Apple introduces two new abbreviations for its users at the WWDC event: HEVC for video and HEIF for images,” Glenn Fleishman writes for Macworld. “These two forms promise to reduce file sizes by as much as 40 to 50 percent while preserving the same quality. However, only iOS 11 and macOS 10.13 High Sierra can currently read such formats.”

“Based on its developer documents and video presentations from WWDC, it’s clear [Apple] have designed everything around the notion of graceful degradation,” Fleishman writes. “That concept means that when the optimum approach fails, a system tries less and less optimum approaches until it reaches compatibility.”

“The new OSes will store everything they capture in the new formats by default, and allow developers to wire in the same frameworks to allow third-party apps to do the same,” Fleishman writes. “When… sharing an image to another app or emailing a video to someone, iOS and macOS’s media software will determine whether or not the receiving part of that equation can reliably play the more compact format. If not, it will deliver up a compatible option.”

MacDailyNews Take: While we expect this to work smoothly, there are still a lot of questions about how it will actually work in practice, how iCloud syncing will work, does this presage an actual 4K Apple TV (it’d better!), etc.

    1. If you don’t like Flash, don’t use it.

      It is interesting how Americans talk about freedoms and how the constitution is sacred.

      Then the next moment they say their government is so evil if it ever requires that everyone step up to reasonable standards (per constitutional rule of law) or that everyone in the community pitches in to pay for what we use. Then, to top it all off, they cheerlead for a multinational undemocratic corporation to have the power to limit their choices and they cheer for a chickenhawk blowhard isolationist to build restrictions to their freedom to travel. You seem so blinded by ideology that you don’t even understand what you stand for.

      Wierd.

      1. It’s not only about one’s dislike of Flash, but also the fact that it is a vector for malware. I’m still constantly having to run update/security patches for Flash. I tire of Flash, and I don’t like running into instances where I HAVE to use Flash. Kill it!

        1. That’s the problem. If people have to use Flash, and Apple prevents it from being installed in macOS, those people are going to have to run another OS.

          If you don’t have to run Flash, don’t install it (no need for political diatribe).

  1. However, only iOS 11 and macOS 10.13 High Sierra can currently read such formats. (Certain smart TVs and some elements of Windows 10 can play the videos, too.)

    The article fails to point out that they’re talking about the current native player. There are 3rd party players that do play HEVC just fine on iOS, macOS and tvOS.

    It would be possible for Apple to update the media kits on older versions of the OS in a point release.
