QuickTime Not Working in OS X Mavericks?

After updating their system to Mavericks, many users complain that QuickTime fail to play many video files, such as AVI and WMV etc. Here you can get the answer of some most frequently asked questions below.

Question: Why QuickTime can't support as many formats as possible?
Actually, Apple has disabled 3rd party extensions. QuickTime has become useless for a large amount of media formats.

Question: After updating to Mavericks, I can't play AVI videos on Mavericks with Perian as uaually.
AVI isn't native to Mac, and Perian hasn't been updated for Mavericks support. That means Perian isn't available for Mavericks now.

Question: There is no quicklook and file thumbnail when I play AVI files on Mavericks.
Apple no longer interfaces with QuickTime anymore on Mavericks, so Quicklook and file thumbnail previews are not supported for Windows media files.

Now I've only found 2 ways to effectively solve the problem above. Solution 1 is that you just find a QuickTime alternative player. Solution 2 is that we use a video converter to convert video to QuickTime available format.



Solution 1: Try a QuickTime alternative player

Through solution 1, I find that Wondershare Player, a free software, is Mavericks supported. It supports MOV, AVI, MKV, WMV, and etc. QuickTime can't play MKV, WMV. After installing a QuickTime alternative player, you can easily play almost any videos on Mavericks. Moreover, Wondershare Player has an easy to use interface, which means you can effortlessly learn how to use it.

Solution 2: Try a QuickTime Mavericks converter

We know that MOV is Mac native format. If you say that AVI, WMV, or MKV, or Divx files can't be played, you can just convert those videos to MOV with a QuickTime Mavericks converter. Then you can play those videos on QuickTime, and also edit them with iMovie.

Wondershare Video Converter for Mac can help you convert your videos to QuickTime supported formats. The conversion porcess is quite fast and easy. With the help of Wondershare Video Converter, you can feel free to play any video on QuickTime just like before.

Just download and install the QuickTime Mavericks converter, and I will tell you how to achieve the conversion process without effort.
