how many frames in your swf?
how large is your swf?
I have 50 frames (that's 50 imported images from photoshop, all are size 1427 x 1763 pixels, resolution 300)
When importing I tick the box "set stage to the same size as photoshop canvas"
that's over 100megs of images so you are probably hitting a flash cs5/system limit.
are you using an alpha channel and layering some of these images over one another?
Thanks, that might be it, I will look at re-sizing.
I'm working in a very round-about way, of creating the frame by frame animation in photoshop, importing it to flash for preview, exporting from flash as png sequence into after effects where I continue animating.
So I will look at exporting the png sequence straight from photoshop - let's see how this goes
is there some reason you cannot use vectors for your animation?
vector animation is one of flash'es strong points.
