Spacebar action changed in Mavericks

[Don Smith]

FOUND IT!

If an MP4 was compressed with Streaming Hints turned on in the Compressor setting it will no longer open with the spacebar in the Finder under Mavericks.

But it always did up through Mountain Lion. Why has this changed under Mavericks?

Now, the two co-workers have three years of MP4 files that, when opened in Quicktime, the files starts automatically transcoding and the conversion operation is asking them to then save the file under a new name.

The co-workers have stopped at that point but I’m asking one of them to go ahead and save the file and then do a Get Info to see if it’s the same file but minus the Hints in the Codec section and to see if the transcoded file is playable with the spacebar in the Finder of Mavericks. I’ll keep you updated.

Thanks Don, I ran across the exact same problem (as you described it) with my upgrade to Mavericks from Mountain Lion as well. Including the attempted conversion from Quicktime. I thought it was because of my outdated version of Flip4Mac at first but an update to that didn’t solve the problem. Please let us know if you figure out how to get back the ability to preview the MP4s using the spacebar. I have years of MP4 and I would hate to loose the ability to preview/play them using the space bar. Converting them all is out of the question.

I have heard on very good authority, that 3rd party codecs and components (such as Flip4Mac) aren’t supported in the QuickLook Finder under Mavericks.

Yep, you are probably right – all I know for sure is that I could play the MP4 files using the spacebar under Mountain Lion with no problem and now I can’t under Mavericks. Flip4Mac was one of the very few software updates I needed to do when I installed Mavericks and the only related to video, so I was hoping that was it. It wasn’t, so now my conclusion is that something definitely changed between the Mountain Lion and Mavericks OS.

Apple removed third party codec/component support from QuickLook.

Here’s a link that addresses this without saying they removed some support: https://support.apple.com/kb/HT3775

Thanks – so they did remove some codec support.

I also found this related discussion on apple: https://discussions.apple.com/thread/5471254?start=0&tstart=0

As they suggested, I tried both adding the additional Apple Codecs in and removing Perian (which I forgot I even had installed). Neither worked for me, so I am still looking for a solution.

[Jeremy Garchow]

Not sure if there’s going to be a quick solution if Apple removed support.

Hi guys,

I had the same issue w/my Macbook Pro after installing Maverick.

Found this on a discussion group, resolved the issue for me.

Hope it helps !

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.

Drag or copy — do not type — the following line into the Terminal window, then press return:

qlmanage -r

Test.

Still having the same problem, tried the above solution from Matt Bisson but sadly no joy. Any more developments on this or is it just another thing to add to the downfall of the mighty apple?

It’s a very annoying issue.

Direct your feedback to Apple and ask for better Quicklook support in mavericks.
