I'm trying to use the kJams MP3 export codec with the Quicktime Player and Applescript. Would like to automate export to MP3 files using Applescript, which requires a 4-character code to identify the type of export. "mp3" is unfortunately one character too short Does anyone have any experience with this?
Thanks for your note. I guess the problem I'm having, in part, in part has to do with scripting. But == as far as I can tell -- it may have to do with how the QT codec is compiled. All codecs have a name (yours is "LAME MP3"), a type ("spit"), a SubType ("mp3") and a manufacturer tag ("PYeh"). The SubType is theoretically four characters, conceived as a long integer; when scripting an export, you use this tag to identify the codec. Not sure how to reference the LAME codec because its SubType has only 3 characters. Have tried a leading and trailing space, NULL, etc. to no avail.
I'm trying to use the Quicktime Player for this task because I have a number of Quicktime movies with individual songs embedded in separate WMA-encoded tracks. I don't know if kJams would be able to separate the tracks and save each one as a mp3 file. I tried the demo version, but it appear to be able to import the files at all. (Perhaps that's just the demo?)
send me a song via email. kjams is pretty good at extracting the audio from just about every file type. if QuickTime can open it then so can kJams in theory, tho i may need to add an extension. be sure to install Perian.
it is 'mp3 ' with a trailing space, and it's 'PYEh' just to be clear
if you're talking multi-track then no, it won't work in kJams.
as a workaround, export AIF, then import THEM into kJams and batch re-encode them to MP3
Thanks again for your quick response! I don't seem to be able to get the export to work via Applescript with "mp3 ", and yes -- they're very odd multi-track files. So I think I'm going for plan B -- export to AIFF (that works!) and then encode as MP3.
Does anyone have any experience with this?
