[MEncoder-users] Urgent problem mpeg4

[Ivan Arcos]

Before, I use this command
mencoder origen -oac copy -ovc lavc -lavcopts vcodec=mpeg4:keyint=25 -ofps
25 -of avi -o destino
but the movie haved low quality

Later I use

mencoder origen -aid 128 -oac copy -ovc lavc -lavcopts
mpeg4:vqscale=3:vhq:v4mv:trell:autoaspect  -ofps 25 -o destino
but the process is very slow and the resultant file is very big.

Anything in the middle?

I have to deliver the project tomorrow. I am grateful for any help
The problem is that the image watchs with a lot of pixels
Thank you
