We need FantaMorph in HD export file.
The 720 AVI output format is relatively old and the granularity is obvious if viewed in 1080i or 1080p.
FantaMorph in 16x9 HD
Re: FantaMorph in 16x9 HD
FantaMorph actually can export movies in any size. See http://www.fantamorph.com/lesson5.html, you can directly choose the movie size 1920 x 1080, or choose "Set Custom Size" to enter any other size.
