How to extract audio from .mpg video file?
Howdy people:
I've got a new project which requires me to normalize the audio on several .mpg video files. When I import them to Protools LE, the audio is absent. I'm guessing this has to do with PTLE not reading .mpg files correctly (they play fine with Quicktime player 6.0). Is there anyone who might offer some advice in this department? I was thinking to convert them to quicktime format -using QT6.0 Pro- but this will take a long time to convert the numerous files and I'm concerned about video/audio degradation during the various conversions. Thanks in advance. X [img]images/icons/smile.gif[/img] |

Have you tried the "import audio from other movie" function on the file?

Re: How to extract audio from .mpg video file?
If you use QT Pro try to extract audio using Export/Sound to AIFF/44.1/16 function and than import this AIFF to ProTools, but I am afraid if there is any possibility to extract audio directly from the file (e.g. if you import mpg into Adobe Premiere you will see nothing in the audio track).
Anybody knows?

It worked ok, so I did not look for another solution. Kuba [img]images/icons/cool.gif[/img] |

Re: How to extract audio from .mpg video file?
I have been able to do this. The trick is to "demux" (=de-multiplex) the audio and video. I found some shareware/freeware Mac tools (BBDemux I think it's called, have to check when I get home). I had tried first on a Windows machine (there are like ten times as many utilities for this), but since I do all my audiovisual stuff on the G4 and leave the PC for e-mail & surfing I preferred an all-Mac procedure

Sean,
Thanks for the help... hmmm... don't have Final Cut Pro... QT doesn't seem to want to deal w/ Mpegs... it works fine for .mov but not .mpg X |

QuickTime Pro...Copy the audio, open the movie, hold the Option Key and Choose ADD to the Movie you want the Sound track in. Make sure the Movie cursor is at the first frame (or whatever frame the audio starts from).
$29.95 from the Apple Site.
