OK, possibly a (very) dumb question, but is there any way of converting a recorded video file to (ultimately) an audio mp3 file - I've got some great concerts recorded, and would love to have audio copies on my ipod.

If not, presumably the audio outs are the only possibility - and then I wondered what what the quality might be like recording from them.

Thanks in advance for any advice.

Yes, just use Project-X in its default (and recommended) mode (demux) where it will turn the .rec into a .m2v (video) and .mp2 (mpeg audio). If you wanted to you could then convert the .mp2 to a smaller .mp3 using Lame (or other tools), or to whatever you prefer.

Oh, and if you are brave enough to step into the options then you can turn off the video output and just get left with the .mp2 (or maybe two .mp2 files -- the extra one being a hard-of-hearing audio track).

I've used streamclip to produce an AIFF and then converted that to mp3 with another program - don't ask me how as I can't remember

Thanks! I had a look at Project-X - blimey! Is there a compiled version anywhere? There is a an old link to a compiled version, but it's dead. I downloaded the Doom9 site, but I just get a Java.lang error on starting (commons-net library not accessible)

Or any other less scary looking application. Thanks again

You've got a partial install. Have a look at this thread and add the extra jar files to the lib directory of your Project-X install.

I have both of those files in the 'lib' file already. The error message isn't the same as that on the thread, instead it reads: see readme.txt[ii] ensure the correct location/classpath, related to the executed .jar at net.sourceforge.dvb.projectx.common.Start.main(Start.java:256)

Any ideas?

I think it's the same problem. How are you running Project-X? If it's from a shortcut, is it starting in the correct folder? The "lib" folder containing the above jar files needs to be in the folder that contains Project-X.jar, and your shortcut needs to be set to start in that folder, too.

Or you can set -classpath and -jar to refer to the directory where these are (best done using a script).

If you are happy with command line stuff MPlayer will also strip the MP2 stream from a .rec file. I have used the following syntax:
mplayer.exe -dumpaudio -dumpfile "OutFile.mp2" "InFile.rec"

(there is also bbdemux)
I would also recomend mp3directcut if you need to remove bits from the MP2 file.

LAME will re-encode from mp2 to mp3 if needed, but a better solution is to find a player that will play the MP2 directly.

example command line for LAME is
lame -V 2 --vbr-new --verbose "OutFile.mp2" "OutFile.mp3"


Good luck

ProjectX would deserve to make the shortlist for "worst user interface, ever".

You might want to try the much more straightforward MPEG Streamclip instead. No compile or install required. "Demux to MPA" from the File menu will extract the soundtrack, and then you could use a Lame frontend like RazorLame to convert to MP3.

Sorry, I forgot to mention you do need to install Apple's Quicktime or the bother-free Quicktime Alternative for Streamclip to work.

Just to say, I downloaded everything, but was overwhelmed by it all. In the end I bought a external USB sound card and connected my laptop to the back of the Topfield using the RCA connectors and just recorded it to a WAV then MP3 file. To these ears it sounds perfect on my iPod in case anyone else wants to do the same thing. Thanks for the suggestions though!

I didn't need to do this. For radio shows I have done MPEG_Streamclip, open .REC, demux to .MPA (rename it .MP3) and use Mega MP3splitter to split into 5 min sections. Didn't cost a bean.

I think you only need Quicktime to convert MPEG to something else.

Quicktime Alternative gave me an awful lot of bother when I tried to install it. Quickly junked never to darken the hard-drive of my computer again.
