Small file gets HUGE?

[wacki]

I'm using this code on a video that's 5 MB's big.

a = DirectShowSource("a.avi" ,fps=25)
a = subtitle(a, "1")
b = DirectShowSource("a.avi" ,fps=25)
b = subtitle(b, "2")


video1 = StackVertical(a,b)

return video1

I open with VirtualDub and save. The file ends up being 500MB's big. 100x larger than the original. Does Virtual Dub save in noncompressed avi's? Is that possible? How do you fix this?

That 5 MB file became 500 MB's when simply played twice.

Hi!Does Virtual Dub save in noncompressed avi's?Yes, unless otherwise instructed... How do you fix this?By selecting a codec, such as DivX, to compress...
