It is still the faq, section 4.8:


> Simply encode all the files at once with mencoder:
> mencoder -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=3000:vpass=1:mbd=2:trell:v4mv -ffourcc DIVX file1.mp4 file2.mp4 file3.mp4 ...

Oh, well, this is much simpler! I will try it.

Any hint about how to extract the registration date from the file?
