Video quality

[sly078]

Hi,

Like I explained in another topic, I'm trying to add a logo on a video and transcode it. I use this command line :

vlc --logo-file logo.png video.mpg --sout "#transcode{vcodec=mp2v,acodec=mpga,vb=1024,ab=128,sfilter=logo}:std{access=file,dst=new_video.mpg}"

I tried to find the best quality I can have. Over 1024 kbits/s (vb parameter) videos are all the same (and a little bit worse than the original). I would like to have DVD quality video (at least 4 Mb/s), do I have to use another command line or different parameters ?

Thanks,

Sly
