Hmm, just as I feared. Yeah, I need to create silent wav files to match the mpegs so I can then run the wavs through another piece of software to create a soundtrack for the mpegs. For this software to do its job, the wavs have to be the correct length.
It was a desperation, “Oh, crap, I’ve got 50 of these to do, there must be a better way,” question.
Thanks.
