You are correct about the uneven number of frames.  I animated a logo on =
a flag using Zaxwerks Flag 3.0.1.  They introduced a "seamless loop" =
function in version 3. It doesn't work as advertised.  Not for me so =
far, anyway. =20

I spent about 5 hours trying to get my animation to loop perfectly, =
trying various loop points and durations.

I didn't get a seamless loop when I had my duration set to 10 sec. =
exactly, but I did have success making it 10:01 (at 29.97 fps).

So=85 back to the drawing board.  I'll try again making it 10:00 =
exactly.  Maybe I'll have better luck at a non-fractional frame rate, =
too.

Rick, thank you very much for the insight.
