@Z Cheema: I dont know what "script marked batch" is, I will search the forums later. Will this make an avi with mp3 audio encoding when i render the project?
@Grazie: If i render the audio alone (NO VIDEO) I can render an mp3 from my project; BUT a silent mp3

, because the audio wont render. So i really dont think that with this "script marked batch" I will get some audio.
