Extracting audio?

zarchy · Post by **zarchy** » Fri Aug 31, 2007 3:41 am

I have an mpeg2 clip that has the audio in Dolby format. I would like to extract the audio from the clip. I know know how to do it with Video Studio, except that I have VS 7 which doesn't support Dolby. I have Movie Factory 3 which will handle the audio. Is there any way to extract the audio with MF?

Well.... You could try making a DVD with LPCM audio. Then, import that DVD into Video Studio. But, I don't think Video Studio had a decent DVD Import tool 'till VS9.

You could also try using SUPER (FREE!!!).

Or, maybe it's time to upgrade one or both of your programs...

I don't upgrade every time a new version comes out, but the Dolby codec and the improved DVD Import should be quite valuable to you.

Thanks! I downloaded Super and was able to do what I needed. I may upgrade my VS anyway at some point., I just dread inheriting a new bunch of problems, LOL.

In Super you should see the ffmpeg encoder/decoder.
Just use the correct extension for the audio that's in the source file.
To find out what streams are in the source file first type
ffmpeg -i input_file.mpg (read the results)
If Dolby Audio then:
ffmpeg -i input_file.mpg -vn -acodec copy output_file.ac3

No conversions performed, simple extraction.

Same with the video portion

ffmpeg -i input_file.mpg -vcodec copy -an output_file.m2v

Just another point if you have MF3 Disk Creator/MF5_Plus or MF6_Plus you can use the "Audio Disk" module to convert/extract audio from videos files, convert audio to different formats, extract audio from CD's, create MP3's etc.

Thanks etech. That's the kind of answer I was originally hoping for. I have MF 3 disc creator, but I don't see an "Audio Disc module". There is a "Create Music CD" icon in the GUI, but this did not seem to provide any of the features you described. At least not in any obvious way.

As I said earlier, I was able to do what I needed using Super. But if it can be done with MF, I wouldn't mind knowing how.

Off topic - I always have the "Notify me when a reply is posted" box checked but I haven't been getting the notifications. Is this normal?

Sorry, MF3 Disc Creator doesn't have this feature.
It came out with MF4 Disc Creator and above versions which has a conversion tool and CD extraction tool..

Yes, I haven't been being notified of answered posts either.

Hi, I hate to point out the obvious but if you're not getting email notice of post replies, check you spam and trash folders.

Good Luck.

Chuck,

Thanks - there is nothing in those folders. Oddly enought I received a notification for your post. I suspect one of the moderators found a problem and corrected it ??

This is nothing new. It has been a problem off and on for some time. It is just hit and miss if you'll be notified.

Maybe one of these days, now that Corel has the reigns, they will update the forum to a more reliable format, like SMF, or Invision Power Boards. The SMF is free, while IPB charges a fee.
