why are people using vqmin=1?? Does it really improve?

ha! you didnt do anything about it so why should it be OK? You have to 
crop it first (-vop cropdetect to guess, -vop rectangle=w:h:x:y to 
finetune) and scale it to proper resolution (something like -vop 
scale=640:336,crop=714:464:2:6), see my last email for good resolutions 
list.
