how to convert x264/aac/.mp4 to xvid/mp3/.avi ?

[Gawwad]

i've heard that it can be done using AviSynth and VirtualDubMod
so say that my source video is located on C:\Sample.mp4 and its fps is 23.976
what is the right script to use?

thanx in advance

For anything directshow related, you should make sure you have avisynth 2.5.7, then start with this simple script:

DirectShowSource("sample.mp4",fps=....,convertfps=true)

where you fill in the fps (typically 23.976) in case the file isn't CFR. You can sometimes even leave the fps parts out. From there, you just fill the script in with any sort of denoising, deblocking, and other tweaking you feel like.
