One of the features I really love in OS X is the ability to preview anything by selecting the file in finder and pressing the spacebar – formally called ‘Quick Look’ – without actually having to open the full app. This is great for both music and movies.
However, if you uninstalled Perian or Flip4Mac or haven’t updated them recently, you will find that a lot of movie files – like .avi, for example – which are not fully supported in QuickTime won’t preview. The answer is to get the latest versions of these two plug-ins:
(hit the green download button (free), ignore the one trying to sell you a paid version).
You should then be able to see any movie using Quick Look.
QuickTime won’t play my video
I’ve been a long time user of TechSmith’s Camtasia screen capture software, primarily for two reasons: ease of use combined with a rich set of editing features. Camtasia for Mac 2 strengthens this product in a number of significant ways although there are still some usability issues that need addressing, as well as room for further improvements in the feature set. In this review, I’ll walk you through what Camtasia has to offer as well as indicate the kind of uses where it excels as an aid to the technical communicator. Read the review…
Not only does VLC play video files that QuickTime can’t play even with Perian, it will also attempt (and often succeed) to play files that suffer from minor corruptions.
If you’re having problems playing a video file in QuickTime, chances are VLC is the answer.
