Hello,

I have QT X, version 10.1 (131) and Perian 1.2.3.
When playing high bitrate scenes of movies that are contained in an MKV file, playback becomes unbearably slow. The same cannot be said about VLC, MplayerX and Mplayer OS X Extended. So you'd wonder why I insist on using QT X instead, and the reason is the contrast and brightness of the player. They are much more to my liking on QT X.

So umm... I require assistance. :D

You can tweak the brightness and contrast to match that in vlc

I know that it's possible, but I tried and couldn't get a similar result.

QuickTime (unlike the other three you mentioned) doesn't have a native decoder for the MKV container so it relies on Perian, which apparently can't handle the high-bitrate fast enough.

Solution: convert the MKV to MP4 or something like that.

and if you do go down that route, here are some good tools to do so:

How long does it take to convert a 90 min video in average? Are we talking minutes, or hours? BTW, the QT X version is 10.0, not 10.1...

That depends on the power of your machine, which video format is used within the MKV container, the size of the original file, available memory etc etc.

The best thing to do is try it and see.

OK, it took roughly 18 minutes to convert a 12.44GB MKV file, however:
1. Neither VLC nor QT X can seek the file. That is, I cannot fast forward the movie.
2. QT X plays sound only through the left speaker. VLC does fine in this regard.
3. The produced file's size is 3GB lower than that of the original file, and I only unticked the embedded subtitle file before I hit the Convert button.
