    So they announced that iPhone 7 could now save videos in H.265. What they didn't really mention is what happens when you send this video to someone else on a different device?

    Have all 64 bit devices had H265 enabled, or does the iPhone 7 now convert it to H.264 before sending? Anyone care to try?

    I am curious about this too. I also wonder if my last gen iPad Pro will be able to play it. Or the Apple TV. I feel certain my 2012 quad-core Mac Mini will choke on it. So yes, does it transcode to share? That seems like it would be very processor intensive and slow.

    He did say something about sharing with other devices wasn't a problem, but I believe that was about the new non-JPG photos and not specifically about the videos. I assume it won't be a problem for videos either, but some details would be nice indeed.

    I expect the mac mini would, any macs with haswell should be fine if they use the hybrid decode functionality.

    Really curious about iOS devices, potentially A7 might not be able to handle it, but the A8 (iPhone 6 in particular) used to have H.265 down for FaceTime usage, if that had hw decode potential then it might make its way to the ATV as well at some point.

    I may have got this incorrect however, and Apple are just bypassing the hardware decode/encode licensing fees and using the processor to transcode...

    Yeah, it wasn't very clear what he meant by that, so would love some clarification on the matter. Even just trying to play an H.265 video on any device running iOS 11 would be useful to see (using the native video player).

    My guess is if the user the file is sent to doesn't have a compatible phone, the file won't play. I can't see the phone converting on the fly. Not enough power, in my opinion (depending on file size).

    I just did some test with my 7+ (on ios11) and my girlfriend's iPhone SE (latest stable iOS 10)

    The video I filmed was in HEVC. When I sent it to her phone with AirDrop, there was a small animation on the AirDrop icon before being sent, it was converting. The video she got on her phone was in h.264 format, I can't airplay it on my ATV 4, but I haven't updated it yet. She can AirPlay the converted file.

    I checked the video format by importing my original video and importing the same video I sent to her phone.

    HEVC is half the size for the same quality! :)

    Edit: updated with all info.

    I'll wait for b2 or b3 to update her phone, the interface is laggy a bit and she's not going to appreciate me putting a beta on her phone :p I will report back at this point!

    Supposedly the A8 and newer have H.265 hardware decode (although maybe not in 4K??) and Haswell (i.e. 4th gen, circa 2013) Intel processors and newer have H.265 hardware decode so it should work on devices of that age or newer natively.

    The High Sierra preview page on Apple.com says that only 6th generation or newer Intel CPUs are supported (which is Skylake, I believe).

    Been an android user for a long time. Wanted to switch to iPhone but, the lack of file manager and h265 is stopping me from doing so until today.

    Anybody can take a screenshot of the file app if you're on beta?

    Also, anyone kind enough to help test what h265 the iPhone 7 can play. Is it hardware decode or software decode? Maybe test it with VLC player also.

    http://jell.yfish.us , click show hevc.
    Test the 1080p 8 bit, 4k 8bit, 1080Hi10 and 4kHi10.

    Will appreciate very much if anyone can do the test. Finally will be able to jump to the iOS bandwagon!

    Only the iphone 7, and maybe new iPad pros, can record / save with h.265/HEVC.

    What I am curious about is whether other devices can play it on iOS 11.

    That makes sense. Haswell can only H.264 and MPEG2 in HW. Broadwell added VP8. Skylake and Kabylake can do HEVC in HW (and VP9).
    --- Post Merged, Jun 6, 2017 ---
    I think existing 3rd party apps won't work because until now Apple didn't expose HEVC in CoreVideo (the A/V framework).

    This is sad. Hopefully they will do it in the future. But if natively can support a h265 10 bit, with AC3 audio codec, and subtitle, I am still able to live with it.

    Has anybody tried shooting a 4K video on the 7 or 7 Plus? I only ever shoot 4K, so have my fingers crossed that gets HEVC. If it doesn't the feature would be a bit of a bust.

    bummer, was hoping the 6s would get the space savings for video....

    Can someone post a sample video and a sample photo of the two new file formats?

    edit: I downloaded a sample H.265 video (not from an iPhone 7) and macOS High Sierra (QuickTime) cannot handle the file format yet.

    strange - I recorded some videos on my iPhone 7 with iOS11 and then conneced to the Windows and copied to my Desktop then opened via VLC - it shows H264 codec even when I recorded in 4K

    So it seems the new formats aren't implemented yet and we can hope that iPhone 6S also get the new formats in one of the next betas.

    might not be true. in camera settings, under format, you have a 'transfer to mac or pc' option where you can set it to automatic or keep originals. It is set to automatic by default and it says 'automatically transfer photos and videos in a compatible format'.

    HEVC 4K is exclusive for the iPhone 7. It will be supported for the other resolutions on other iPhone models.

    you're right! I changed the option and now:

    movie recorded with H264 has 32 MB
    movie recorded with HEVC has 14 MB

    great! I will check with pictures now

    My 2.6GHz i7 Mac mini (late 2012) does fine playing 1080p HEVC through Plex, VLC, and a few other video players. It can't handle 4K HEVC; it stutters badly. (I switched to HEVC for all of my video-encoding a year or two ago.)
