(but interlaced decoding is buggy atm - may crash due to invalid memory
accesses)

{{{
ANIM 16i/ANIM32i
These two formats are well worth experi-
menting with if you have the time. They are
only useful H you are going to play back ani-
mations at maximum speed all the time, but
the advantage is a 50% drop in file size. The
format works by taking advantage of the
Amiga's interlaced mode, which doubles the
resolution by using two screen refreshes.
Ordinarily this can appear as a form of flicker-
ing when used to display the largely- static
Workbench, but fast moving animations can
benefit. The original animation must have
been created in interlaced mode, and when
saved the new file will discard every second
line - which would not have been seen
anyway."
