Thank You for Your time and answer, François: > Maybe you can try vcodec instead of vcompressc ... vcompressc is not > documented on the mencoder man pages. All right, I will try it. - But my problem comes not from a bad parameters string of mencoder but from after upgrading - from lenny to squeeze. - That's why I have asked. Also, I do not pretend it to be the best optimized solution. so if have one, please, share it w/ me.
