OK, I had this problem before and I thought it was just a glitch, and I never tried it again.

But now, I realize that every time I import an MPG file to iMovie, it imports the video fine, but it has no sound!

Is there any way to make it work right? This is a video from a friend's Sony digital camera, and he needs me to compress it for him.

QuickTime in general (and all apps like iMovie that use QT) doesn't deal well with muxed audio in MPG files. You should use another app to extract the audio from the file first.

OK, do you have any suggestions for a program to extract the audio? I tried Amadeus but it doesn't seem to have that functionality.

Try ffmpegX.

Grr, ffmpegx says the source file doesn't contain any audio or video, so it outputs a blank mp3 file.

MPEG Streamclip is the must-have app for this kind of task (demuxing). Very powerful, easy to use, rock solid, and free. You may need the MPEG-2 Playback Component from Apple, depending on what type of MPG file the camera spits out (you didn't tell us this in your post).

That said, if ffmpegX can't decode the video and audio, you may have a corrupt file. Most Sony cameras I've seen have outputted AVIs with the Motion JPEG codec, so I'm not familiar with the MPG from these things. Is it MPEG-1 or MPEG-2?

The camera is a Sony Cybershot DSC-W5, this is what DPreview has to say:

Quote:

MPEG Movie VX Standard/Fine Mode with Audio
Captures VGA (640 x 480) high frame rate (up to 30 frames per second) audio/video clips with length limited only by the capacity of the media. Video mail mode captures smaller file sizes suitable for email.

I'm downloading MPEG Streamclip and the component now. What's strange is that this file plays just fine in QuickTime 7, but iMovie can't read the audio Stay tuned...

Update: SWEET! Thanks Dorian! I demuxed the audio to aiff and imported it into iMovie, didn't need the MPEG-2 thing. Working like a charm!
