Apple apps such as QuickTime Player, Photos, and Keynote work with many kinds of audio and video formats. Some apps prefer specific formats, but QuickTime movie files (.mov), most MPEG files (.mp4, .m4v, .m4a, .mp3, .mpg), some AVI and WAV files, and many other formats usually work in most apps without additional software.

Older or specialized media formats might not work in your app, because the format requires software designed to support it. If that happens, your app won't open the file or won't play back its audio or video.

How to search for an app that works with your file

Quicktime Avi Codec

Faasoft AVI to QuickTime Converter is an all-in-one AVI to QuickTime Converter which not only supports various kinds of AVI videos, but also absolutely ensures the converted files are compatible with QuickTime. Better yet, Faasoft AVI to QuickTime Converter has two versions: Mac. MOV was developed for Mac OS and QuickTime application by Apple. MOV supports MP4 codecs like H.264 while AVI does not. On the Internet, where the compatibility demands are high, AVI had become very popular. This format is supported by almost all players, even portable devices like video players and video smart phones.

You might already have an app that supports the format of your file. If you don't know which of your installed apps to try, your Mac might be able to suggest one:

1. Control-click (or right-click) the file in the Finder.
2. From the shortcut menu that opens, choose Open With. You should see a submenu listing all of the other installed apps that your Mac thinks might be able to open the file.

If none of your installed apps can open the file, search the Internet or Mac App Store for apps that can play or convert the file:

• Include the name of the media format in your search. To find the format, select the file and press Command-I to open an Info window. The format might appear after the label Kind, such as ”Kind: Matroska Video File.”
• Include the filename extension in your search. The extension is the letters shown at the end of the file's name, such as .avi,.wmv, or .mkv.

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:

• 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

• Download Niceplayer , it's pretty great -- and those folks are doing a fantastic job.
• Support each other on our Google Group list . 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 Child's Play , Ronald McDonald House , or the EFF . 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.
