A notice to all of our users and supporters We began the Perian project over 6 years ago. We wanted to simplify viewing your content. Our team has attained that goal and with that in mind, Perian will be retired soon. Our stewardship has been a blast but it's time for all of us to move on. From the beginning we kept Perian simple.
Our preferences were minimal, updating was easy, and we gradually grew the product to add in extras like subtitles and different formats. We've contributed a lot.
Today, Perian stands as complete as it ever will be under our stewardship. There are some projects that we never got to. As an example, we would have liked an official, flexible, and well-documented import API to speed up MKV.
We hit a brick wall there. Still, we reached a great stopping point and Perian's installed userbase proves how valuable this tool became to so many people. Starting 90 days after the final Perian release, we will no longer provide support. We'll wrap up our loose ends, pack up our bags, and move on to new and exciting projects. Here's what our roadmap looks like:.
Something to do with High Sierra I'm guessing. It's not the Dolby codec AC3 conflict so many others on Windows are dealing with. This just seems odd since everything worked great as of yesterday and nothing has been updated or deleted from the Mac OS.
We will soon release the final version of Perian, including all the fixes we've worked on since the last release. It may - or may not - work on 10.8. We will post the source code to either Google Code or Github.
Here's what we're looking for from you, our users., it's pretty great - and those folks are doing a fantastic job. Support each other on our. We mean this. Just because we aren't helping anymore on a regular basis, that doesn't mean that you can't. Are you a developer? Pick up where we left off.
Join us on #perian on irc.freenode.net. Yeah, we're all pretty busy - so stick around after asking your question. You may have to wait a bit for an answer. Chalk it up to asynchronous tech support. Want to donate? We appreciate the thought.
It's hard times these days and your money will make a bigger impact elsewhere. Consider, or the. We no longer accept donations. A final word: If and when Perian stops working, try looking into VLC or MPlayer OS X.
Sure, they're not Perian, but they offer great software still under development. Thanks for all of your support over the years. It has meant a lot to all of us.

Installation and Removal of Perian Please consider removing obsolete QuickTime Components: FFusion, Xvid Delegate, 3ivX, DivX, DivX Decoder, XviD, msmpeg4v1, msmpeg4v2, AviImporter, EXM4S2, Casio AVI Importer, AC3 Codec, and MatroskaQT. How do I remove Perian?
Open the System Preferences. Select the Perian pane and 'Remove.' Now 'Show All' preference panes, control-click the Perian pane and 'Remove 'Perian' Preference Pane.' Frequently Asked Questions Why does it take so long for MKV to load?
QuickTime expects to know the location of every single frame in a movie in order to play it. This is easy with its native format, MOV/MP4, but more difficult for several others, including MKV. Perian has to read in the entire file in order for seeking and playback to work.
Does hardware acceleration for H.264 work with Perian? QuickTime supports hardware acceleration for some profiles of H.264; however, which profiles these are is not documented and may change on different Mac models. We do our best not to interfere, and some MKV files are known to work with hardware-accelerated decoding. I thought Perian allowed me to play MPEG files, but it can't.
The term MPEG covers more than just a file type; it also defines audio and video compression methods. Perian allows playback of these audio and video compression techniques, but it does not allow the ability to open the MPEG file format. This is due to limitations within QuickTime itself, and we cannot solve it until Apple designs a better interface. See on the subject. Will there be a version of Perian for the iPhone?
Unfortunately no, the iPhone does not have QuickTime. Since Perian is a third party component for QuickTime, we would need the iPhone to have QuickTime before we could get Perian onto the iPhone. What if QuickTime for the iPhone ends up in a future update? We are concerned that the iPhone, while a great device, is just too slow to play the type of files that you would use Perian to play. I submitted a bug report and I was told it was fixed in SVN; what does this mean? SVN refers to the system which the developers use to store the source code that makes Perian. If an issue has been fixed in SVN, then that means the developers have tracked down the issue, and believes it to be fixed.
At this stage, it requires further testing after which it will be included in the next release.
Our Macs are getting slimmer all the time, but the photo and video files we pack them with aren't on the same diet. Well, until iOS 11 and macOS High Sierra debut, that is. Both new operating systems will support two codecs designed to double the amount of compression that can be applied without losing quality. Here's what you need to know about HEVC and HEIF and how they work in High Sierra. What are HEIF and HEVC?
HEVC stands for High Efficiency Video Codec, and HEIF is High Efficiency Image Format. HEIF works as a still image container for the HEVC codec, which is the successor to H.264. In fact, HEVC's other name is H.265, but Apple is going with HEVC. What does HEVC do better than H.264? HEVC is designed to save space and bandwidth, which will be more and more important as more 4K and HDR video becomes available to stream.
Apple says the standard can compress 4K video files to 40% of the size without losing quality, which will let iOS 11 and High Sierra users store more of their own videos before running out of drive space. Alternatively, you can keep an HEVC video file about the same size while doubling the amount of data, which will decrease the bandwidth needed to move 4K and HDR video around.
What about HEIF? What's its benefit? HEIF has an added benefit too: It can store groups of images as a single file. This is especially handy for things like burst photos or keeping an edited image and the original in the same file. It's also a natural fit for Live Photos (including the debuting in iOS 11), which act as one photo in your library, even though they contain multitudes. Remember, Apple's computational photography approach in iOS means the camera is capturing multiple frames every time you press the shutter, then combining those for a better-looking result. Tricks like long exposure effect in iOS 11's Live Photos and the iPhone 7 Plus' Portrait Mode work the same way.
HEIF containers can keep all that data wrapped up, fully intact, to send back to your Mac running High Sierra for more editing. Are these replacing H.264 and JPEG?
They're the next generation of those standards, but when you export a video to post to YouTube, it's going to be H.264. If you email a friend a photo, it's going to be a JPEG. Right now these are under-the-hood improvements that shouldn't break compatibility or cause formatting headaches for end users. You'll use your devices and apps in the same way you always have. Will HEVC video look better? If you compare an HEVC and a H.264 video side by side, yes it should.
A movie trailer with H.264 and H.265 encoders in HandBrake and found the HEVC (or H.265) video had fewer compression artifacts and smoother movement. HEVC compensates better for faster motion, for example, which should be especially welcome news to fans of action films and sports, once more content starts streaming in that format. Will every device with iOS 11 capture photos and videos in this format?
And that's how they're stored on the Mac? Not all the devices. To capture HEIF and HEVC files, you'll need an iOS 11 device with an A10 Fusion chip or better: iPhone 7, iPhone 7 Plus, 10.5-inch iPad Pro, or 12.9-inch iPad Pro from 2017. All Macs running High Sierra can encode and decode those files, so when you transfer them to your Mac, they'll stay in the same format until you decide to export them as something else. Of the hardware requirements for HEVC and HEIF support in iOS 11 and High Sierra.
It's definitely worth a look if you have older hardware. But at the end of the day, these are under-the-hood format changes that shouldn't directly impact your workflow. I heard newer Macs have an advantage with HEVC? You heard right.
Newer Macs, including the late 2015 27-inch 5K iMac, the 2017 21-inch iMac, and MacBooks and MacBook Pros from 2016 and 2017, will support hardware acceleration for coding and decoding HEVC video. The Kaby Lake chips in the 2017 laptops also support HEVC decoding. Hardware acceleration means faster encoding times in pro apps like Final Cut and Motion, and longer battery life when you're playing back HEVC video. Older Macs running High Sierra will still be able to play back HEVC video, but the process is a little hardware intensive, Could HEVC help 4K video come to the iTunes Store and Apple TV? That's very likely the roadmap. Right now, the iTunes Store and the Apple TV max out at 1080p content, but when Apple does make the jump to 4K, HEVC will reduce the bandwidth needed to move those files around.
Apple isn't super late to this party just yet. Right now, Netflix and Amazon have some 4K and HDR content available to stream, but you're usually stuck using the built-in Netflix app on a 4K smart TV. Amazon's Fire TV set-top box supports 4K videos over Amazon Prime Video, if it's connected to a 4K TV. Tim Cook did hint at more Apple TV news coming later this year, so maybe a new Apple TV box is in the works.
Now that Apple's dabbling in its own TV shows, that would be a natural place to start. After all, Netflix and Amazon's original series make up the bulk of their own 4K offerings. Will third-party image and video editors support HEVC and HEIF? It's not an open-source standard, so software makers woud have to license the patents to use the codec. H.264 worked the same way, but right now HEVC is more expensive. Of course, Apple tends to drive adoption, as it did with H.264.
Settling on a 4K codec isn't so easy. Google currently uses V9 for 4K video on YouTube, but Apple's Safari browser doesn't support V9. The is working on a codec called AV1 which should be out by the end of this year, but Apple hasn't yet committed to natively supporting that either. More questions? The High Sierra betas don't fully support HEVC and HEIF just yet, so the picture is still coming together. If you have more questions, let us know in the comments.
