Which one is better for 352x576 video, bicubic or lanczos?

It depends on your source. Use bicubic only for "upsizing" a movie. Not for downsizing. I believe lanczos is good for 1:1 and for downsizing, but not for upsizing.

Hi kwag,

What do you mean with "1:1" ?

No resize at all. Input res.=Output res. Not aspect related

If Input res.=Output res. then you don't need a resizer! do you

True, and the filter should then operate in "passive" mode, because it doesn't need to do any work. That is, if the filter is smart enough
But then again, no, you don't need the filter in place
