-vf pp=lb

Hello,

Is there a difference in terms of interlacing between a talk show
an a movie. Both need to disable interlacing if one keeps full resolution ?

I maybe not clear.

If I mencode a talk show, news ... ie studio broadcasting or programs 
made for TV especially, I remark that the quality is better
with -vf pp=lb. Is that the same with a movie ?

what is better pp=lb or pp=DEINT_TYPE ?

do this filter work with -voc copy ?

Any idea is welcomme ...


Thanks. Nicolas.
