Batch Audio Compression of Many AVI files!

[Wesmosis]

hey guyz
plz I need a favour
I have about 250 xvid avi files, of varying names and sizes....and thier audio size quite big
I need a trick or something to do a batch audio conversion into mp3 or wma without processing each file in VDub and do the Audio Compression separatly! is that possible?!

[buzzqw]

1) no crossposting

something like demux audio (with avi2wav, even command line for batch processing), process with lame.exe.

But for remuxing avi+mp3... don't know, avi_mux gui has a batch scripting guide (not so easy...)

BHH

[Wesmosis]

I C ....thanx for answering
but I don't wanna Remux or DeMux ...only I wanna recompress the audio of the AVI fle into lower bitrate in order to reduce the size a little bit....but I have alot of AVI files and that's will a very lng process of Loading each avi file in the virtualDub and choose the Audio Compression and proceed......
any other solution

You can use VirtualDub script to do the lot.
Google and have a look around and you'll find plenty of examples.

If your still stuck in a month - i'll script it for you. Too busy at the moment.

Good Luck

waiting for you script

open up virtualdub, open up a file, configure your settings, press f4, edit --> process directory, start jobs.

[bobmaster]

stephanV's way is easier/better but here is the script anyway.

Just an example, modify it to what you need.


declare eps;

eps = "Video1.avi";

VirtualDub.Open("C:\\INPUT\\" + eps,"",0);
VirtualDub.RemoveInputStreams();
VirtualDub.stream[0].SetSource(0x73647561,0);
VirtualDub.stream[0].SetMode(1);
VirtualDub.stream[0].SetInterleave(1,500,1,1,0);
VirtualDub.stream[0].SetClipMode(1,1);
VirtualDub.stream[0].SetConversion(0,0,0,0,0);
VirtualDub.stream[0].SetCompression(85,48000,2,0,20000,1,12,"AQAEAAAA4AEBAAAA");
VirtualDub.SaveAVI("C:\\OUTPUT\\" + eps);
VirtualDub.Close();

eps = "Video2.avi";

VirtualDub.Open("C:\\INPUT\\" + eps,"",0);
VirtualDub.RemoveInputStreams();
VirtualDub.stream[0].SetSource(0x73647561,0);
VirtualDub.stream[0].SetMode(1);
VirtualDub.stream[0].SetInterleave(1,500,1,1,0);
VirtualDub.stream[0].SetClipMode(1,1);
VirtualDub.stream[0].SetConversion(0,0,0,0,0);
VirtualDub.stream[0].SetCompression(85,48000,2,0,20000,1,12,"AQAEAAAA4AEBAAAA");
VirtualDub.SaveAVI("C:\\OUTPUT\\" + eps);
VirtualDub.Close();

ect...


This script will encode Video1.avi and Video2.avi from "c:\input"
It encodes Stream 0 (first audio track) to MP3-128Kbps. (Assuming you have LAME ACM codec installed). The output video will be saved in "c:\output". The only thing that changes is "eps = " the rest you can just copy and paste for as meny videos as you need.

TIP:
An easy way to make a list of files is - in command prompt type "dir /b > list.txt"

Hope it helps
