Source是640x360的影片，上下要刪到640x272，只要

AviSource("?:\???.avi")
Crop(0,44,640,272)

二行就行了啊，為什麼還要作Resize呢?

Lanczos4Resize：

Lanczos4Resize is closely related to LanczosResize (correct name: Lanczos3Resize). The latter uses 2*3=6 lobes and the former 2*4=8 lobes to do the resizing. The result is that Lanczos4Resize produces sharper images. Especially usefull when upsizing a clip.

用估狗查的...
