QuickTime 10.0 with No Sound

virtualplaid · #1 October 10th, 2009, 10:27 AM

I imported an MPEG 2 into QuickTime 10.0 and I don't get any sound. I thought it was maybe my video camera (Sony Handy Cam DCR-SR85) but there is sound on that when I play back the video. I exported the video to a .mov but still no sound. What's up with that? Please help me...I spent the $20 bucks for Snow Leopard to read MPEG 2's and now I don't get any sound??? I need some help soon!!!

Thank you for your help in advance!!

Well, Apple has just gone nuts with their nomenclature surrounding "X." While "Mac OS X" translates to "Mac oh-ess ten," I believe "Quicktime X" translates to "Quicktime ecks," not "Quicktime 10." Seems a bit silly that they'd jump from Quicktime 7 all the way to
Quicktime 10, but then again, the new Quicktime X is a radical departure from that which was once Quicktime 7...

...but I digress...

More than likely, the video and audio coming from your Sony HandyCam is "muxed" in the resulting video file. What I suspect you need to do is "de-mux" the audio and video into two separate files, then recombine them so that Quicktime "understands" them.

A Google search for "Mac OS X demux" turns up a lot of hits, some old, some new. It may take some digging to find a decent "demuxer" for Mac OS X.

You may also want to try a video conversion software like Handbrake... you may be able to convert the file to another format, which Quicktime then could understand.

That and you may need to get the MPeg-2 player.

"But it is in the QuickTime X! You don't needs it!!" screams the Apple people. I got it a long time ago for my standard QuickTime.

After upgrading to SL, I powered up the QTX . . . opened a [Porn video--Ed.] Shh! opened a video I watched all of the time--a documentary thank you very much [A porn documentary.--Ed.] . . . and . . . nothing!

Now, in this case it would not recognize the file. I went back and forth with Apple. Finally, a tech admitted that I "may" need to have that codec. This is particularly true given they still sell the damn thing!

Fortunately I saved my original system--and downloads.

I added back QT7--updated it--readded my MPEG-2 component . . . voila!

Now will that help you? I do not know. But if you desperately need to watch MPEG-2 very well may. VLC--a free player--plays a lot of things--a lot of things. That might work for you over QT. The other thing to get is Perian and Flip4Mac. If after ALL of those FAIL . . . and whatever EDCC's advice FAILs--if it will--then you may have to do that--get the MPEG add-on.

Do not know if that helps; just writing from personal experience.

I do find the "old" QT7-Pro FAR easier to work with than QT X, for what it is worth.

I am having the same problem. Bought the mpeg 2 codec, which allowed me to view videos taken by my sony handycam but doesn't play any sound. Is there any easier way than to "demux" it to get it to play sound? I can play them with the VLC player but still can't import them into imovie to edit them.
