I don't know how Nuke works, but if it reads scan lines top-to-

bottom-to-top (as opposed to accessing the scan lines in random

then reading chunks of 16 lines might actually be faster than reading
individual lines. Also, with 16-line chunks you tend to get slightly
better compression.
If you're zoomed out in Nuke, the scanline renderer is only drawing
every Nth scanline, so with Zip it will only decode and cache the
lines it needs. That's why Zip is a good choice for Nuke. Virtually
every other program reads the whole file every time, so Zip16
performs a little better for them.
