Oh, it's also worth noting that I always use JPGs now instead of PNG. I've found they play just as well and leave the final animation size considerably smaller. I have one animation that is 420 frames at 24 fps and is less than 9MB. Most are only 1-4 MB I think. Speaking of, that exact same animation plays slightly lagged on my D1, but perfectly smooth on D2 and DX. It has sound along with it, which I believe may help your animation. I've made at least a few animations first without sound, then adding sound later. In one case, my animation was 252 frames at 24 fps (should be 10.5s) and took 30 seconds from start to lockscreen. After adding sound, it finished perfectly on time and in sync with my sound file! I've been meaning to experiment with a blank sound file to speed up my animations. What do you think about helping with that experiment?
