Since upgrading to Mavericks, many movie or video types no longer are available through Quick Look - and must be converted to play through Quicktime. The convertion can take a awfully long time, depending on the movie size.
Why is that - because they worked fine with Mountain Lion.
The most noticeable examples are .MP4's
Also, in QuickTime, when the movie control hover box appears on a movie that it does open, there is a small but noticeable boost up in video color saturation, or maybe a reduction in saturation when the box is not present. Very, very annoying.

Thank you so much!!
I can't believe Mavericks removed so many codecs from Quicktime (and Quicklook)
But this codec solved everything and I wouldn't have found it if it weren't for you!
I tried installing ProApps Quicktime Codecs but I still can't quick-look MP4 files, sadly.
Thank you for this.
Do you know about some codecs for wmv?
I'm having the same problem. If I double-click certain mp4 files they 'open' and start a conversion process. I then have to save the file as .mov file in order to save it in a viewable format. I tried downloading the pro codecs, but they made no difference. Any other thoughts anyone?
Thanks!
this is really bad. we have a vast collection of movs with PNG or animation codec, that we need for live video shows. we need to quickly preview these and quicklook was just perfect. why does apple do that? welcome to the post-productivity era...
i hope this gets patched.
Also having the same problem. Installing ProApps Quicktime Codecs didn't work for me.
For me the culprit were "hint" tracks embedded in the MP4 video.
To remove hint tracks from existing files you can use the excellent "Subler" MP4 muxer/editor (OS/free).
Just delete the hint track(s) in the list, save, voila.
I can't believe this ... as it seems, Apple want to prevent me from using Premiere Pro, by not allowing the download of the ProApps Quicktime Codecs unless I use an apple editor like Final Cut, Motion or Compressor. If that codec really is what I need, and it it is near impossible to back down from Maverick ... does that mean I must buy a new editing software in order to use my favoured software on this free upgrade? And ... as many editors ... I do not have a week to solve this!
You might try using Pacifist to install the codecs from the updater.
This worked for my case. I wonder how did that tracks got into my videos? Is it already there or added after upgrading to Mavericks...
Pacifist has good reviews, and I now have it installed - but would you please direct me, Old Toad. You mean I will run the codecs using Pacifist ... ? I am getting increasingly frustrated and somewhat upset here ... and I am afraid of doing something to screw everything up.
Well ... I installed it, by clicking on the folder and accepting installing in default location. All the Quicktime codecs seemed to already be there, while the video codecs were filled in place - but no change for my .MP4 files. I still can not open them in Premiere Pro or see them in quick view. I'm screwed. 😕
Subler worked. What it appears is happening is that the new version of Quicktime will not play certain encoded videos that have "hints" embeded in their file. Downloaded videos often embed these hints to somehow ensure they download correctly.
Subler is a free application. The link is in a previous post. It takes a few tries to understand it. Basically, you open the video you are trying to fix, and it will show the video, the audio - and in my case - 2 additional unnamed "hints". I deleted those hints through Subler, and they were remuxed (?) a process that took less than 1 minute (as opposed to much longer to convert the entire video).
The end result was it solved the issue.
Apple would be advised to somehow explain this -- because I know many other Mac users who have been scratching their collective heads since the Mavericks update. You simply cannot believe how you depend on Quick Look - until it doesn't work with your files. I do a lot of work with video - and this was maddening.
Problem solved. All good. A big thanks to Block Rocker
Now... if I could only figure out why Apple adds a \ to my name. It's O'Bryan ... not O\'Bryan.
Pacifist will install the codecs just like the installer would but it doesn't require the pro apps to be present. I've not run the codecs but have used Pacifist to install iDVD themes from updaters.
Why No Quick Look with MP4 in Mavericks?
