auto'ing an AC3 to MP3 re-encode

[Robm2kx]

ey people, have a simple question about automating the below steps, i have done some of it but am just wondering if theres an easier way

1. de-mux an avi with ac3 into sound and video
2. re-encode the ac3 into mp3
4. rejoin the two

i have saved virtualdub settings to strip the audio and then ran the command line switch to create and run jobs per the settings (VirtualDub.exe /c /s"vdub.no.audio.set.vcf" /b"source dir","dest dir" /r /x)

I have found no way to automate or create jobs to "save wav" in virtual dub to get the audio

I have managed to crudeily make a batch file calling besweet to transcode the ac3 to mp3

and i am not sure how to automate nandub to load the video and audio and save as avi

can anyone offer any assistance or recommend a better program / method ?

What happened to step "3" :confused:

Try:
Install the ac3 acm codec.
Install an mp3 acm codec (lame).
Set video to direct stream copy.
Use full processing on the audio, compress to mp3.

All done in one shot.
