Mountain Lion got animated GIF support for Quick Look, but the animations show as slowmotion. It renders very slow even if the GIF has a fast frame rate. Is there any way to improve this or replace the Quick Look functionality with something that works better?

    With which mac do you get this kind of behavior ? Commented Oct 20, 2013 at 18:15
  • Any. I have used 13 and 15 MacBook Pro (different models), also MacBook Pro Retinas and my own MacBook Air 13 (this year's model).

  • Could you attach such a GIF for us to test?

  • He's right, compare gif between QuickLook and a web browser. They are significantly slower on quicklook. (Running on a late 2012 iMac) Commented Oct 21, 2013 at 10:46
  • Yes, I'm not talking about a particular GIF but any GIF. They all look quick and smoth on any browser, like Safari or Chrome, but really really slow on Quick Look.

OS X Mavericks, somehow, solves this issue.
