No sound in mpeg-1 to mov conversion

tbalazs · Sep 10, 2003

I have a short mpeg-1 clip originally converted from wmv format by TMPGEnc. The mpeg plays fine in many players, including Quicktime.

When I convert to .mov using Quicktime Pro the video converts OK but the audio is not picked up and the .mov is completely silent.

I am using all of this under Win Me (unfortunately

).

Anyone have any ideas?

Thanks,
Tony.

Try and just export teh audio first in QT. If the audio does export, then I dont know what is up.

IF no audio can be exported, it seems QT is having problems with the mpeg file. Waht version of QT are you using?

I'm having the same problem with Quicktime for Mac OS9 - have you solved the problem tbalazs?

I've also got Adobe Premiere but it doesn't import Mpeg files or I'd have the problem solved by now....

An odd limitation of QuickTime is that you can't export the audio from an MPEG-1 movie that uses multiplexed streams for audio and video.

Fortunately, in your case you don't need to. Open the .mpg file in QuickTime Player (pro version). Choose "Save As" from the File menu (save as self-contained, use .mov file extension). This creates a .mov file with multiplexed MPEG1-compressed audio and video.

You can't EXPORT the audio, but you can Save As a .mov file, which for your purposes is the same thing.
