QuickTime convert .avi to .mov with OS X Mavericks

If you cannot use QuickTime 7 to play AVI movies, you can only turn to some other software to convert AVI to MOV. After all, AVI can be encoded with different codec and not all codec are supported by Perian.

Again some of you people don't get it.

I had a perfectly working computer.

my peripherals printer HP office jet and external western digital 6tb raid hard drive.

Itunes with 5 apple tv units doted around the house.

After I "upgraded to mavericks" my external HD stopped working and the data was wiped out...

Why? Because mavericks destroys the raid controller on western digital and lacie drives..Don't take my word for it look at the forums....

Western digital are compensating me very niclely.....But i've still lost the data..

The office jet can no longer scan because of a problem with mavericks, don't take my word for it read the forums.

As for the nature of this thread.......quick time 7 did not work for me and adding perian did nothing.

Something has happened to my files. Basically the files are there but are not opening. For a second the converting box appears then it stops and takes me to the QT info page. With QT 7 it just states that the file cannot be opened same with perian...

I suspect very vew people would "get it" when you completely change the topic as you have done by moving from AVI conversions to raid controller destruction and the loss of data. I hope you have been providing feedback to Apple to include specific drive and model information for hardware and contoller software. In fact, you might want to consider opening your own discussion for this topic. Unfortunately, this appears, to some extent, to be the luck of the draw in your choice of harware/software.

For instance, in researching the problem, I see the Pegasis Technology R-4 may be affected but my R-6 is not listed as a problem raid. And, while numerous WD procuts seem to have problems, none of the WD drives used in my Drobo Pro and Drobo 5D remain functional. In addition, my CalDigit raid is also uneffexted nor has my HP Envy stopped printing or scanning. Thus, it appears the problems you have are not generic to Mavericks alone but Mavericks in conjuction with certain devices using specific controller software. This is a potentially serious matter which needs to be addressed as soon as possible. The more feedback sent the more resources Apple is likely to devote to the matter.

AppGeeker video converter is a tool I use that converts videos to just about anything else on my iMac. I do a lot of WMV to MP4 and use it all the time. If I recall correctly it does handle AVI as well.

See: How to Convert AVI to MOV (or MOV to AVI) on Mac/ Windows

This software is extremely easy to use and will help you do some simple editing for AVI if need.

I have a Pentax K5 (about 3 years old) that records in the .AVI what ever (format?, container?) and under Mavericks I can see them in quick look and they will open in iMovie 9.09 but not in in the latest version of iMovie. the are (I think?) 1920*1080 with 16:9 aspect ratio at 25 fps.

Is there any way to convert them that keeps the high deffintion format?

Nevermind I found one.

Your AVI files are probably encoded as Motion JPEG video with PCM (WAV, AIFF, Little Endian Integer, Big Endian Integer, etc.) audio which remins QT X, QT 7, and QL compatible even under Mavericks. Since these are legacy compression formats, they are still "passively" supported by both the AVFoundation and the 32-bit QT embedded structures and need not be "converted" (transcoded to other compression formats) to get them into an MOV file container. Both QT 7 and the free MPEG Streamclip app can copy your AVI compressed data directly to an MOV file container without modifying display dimensions, aspect ratio, or the frame rate. (I.e., the data is not modified in any respect which also means there is no degredation to video quality as can often be the case when transcoding or exporting the content to different compression formats.)

Nevermind I found one.

If you are using an app to actually "convert" your AVI files to other compression formats, you may wish to try the data copy workflow mentioned above to see which workflow you prefer.

Tried installing an older version of Quicktime 10.0 but the new OS Maverick rejected it. Guess will need to switch player to either Divx or VLC.

Each Mac OS X version (Snow Leopard, Lion, Mountain Lion, and Mavericks) has a different version of embedded QT X suport structure and each embedded support structure only supports the specific apps which are compatible with that Mac OS system. (E.g., the QT X Player v10.0 is only conpatible with the structure embedded in Mac OS X v10.6 Snow Leopard.)

What do you mean with "an older version of QuickTime 10"? http://support.apple.com/kb/HT3678 might help...

Why QuickTime Won't Play AVI Files?

AVI (Audio Video Interleaved) is a container format designed by Microsoft to wrap audio and video stream together. The video in AVI file can be compressed by many kinds of codec, such as MJPEG (Motion JPEG), MPEG-1, MPEG-2, DivX, XviD, WMV and others. To play all AVI files, your player must support all of these codecs. So far, no matter you are a Windows user or a Mac user, QuickTime only natively plays AVI files with MJPEG video.

As a great open-source QuickTime component, Perian is the saver to allow QuickTime to play all kinds of AVI videos for Mac users. Unfortunately, the latest version 1.2.3 of Perian is not compatible with Mac OS X Mavericks (10.9), Mountain Lion (10.8) and Lion (10.7).

In order to solve "QuickTime won't play AVI" on Mac (Mavericks included) and Windows, it is best to convert AVI to QuickTime more popular formats like MP4, MOV.

Converting everything isn't really a friendly or viable solution for many as some people may have a LOT of files and every single time you convert a compressed format to another format you LOSE QUALITY. Thus, it's usually BEST to use a viewer that can play the format natively. Something like VLC or XBMC (now called "Kodi") can play most formats natively and thus lose no quality and require no conversion effort on the user's part.

What is lost by Perian abandoning the Mac community combined with Apple changing Quicktime to not support the same plugins is the ability to view these files using Quicklook (where you press the spacebar to preview the file in the Finder). It would have been nice if someone would have offered to pick up supporting Perian where the developers left off, but it might be technically impossible to support Quicklook at this point without Apple's help if they changed the plugin formats for Quicktime to either not exist or are different. Either way losing Quicklook support in OS X for all formats has been one of the biggest steps BACKWARDS for OS X in its entire history. It's a shame Apple can't recognize the fact that there are other formats out there besides the ones Apple supports. Some of us need to exist in a larger world than just Apple. Sadly, Apple has always done what it wants rather than what its users need.

If your AVI is encoded with Motion JPEG (M-JPEG), you can use QuickTime to convert AVI to MOV.

If your AVI is encoded with other codec, you may try QuickTime Pro or a third party to convert AVI to MOV on Mac or Windows
