Help needed with flash

hi guys i need some help,
i’m trying to make some clouds move in flash, i made some pics and made small jpg’s of it and imported them in flash put them in a movie clip woth a length of 300 frames at 15 fps.
it louks crappy the clouds move very shaky not very smooth, is there something i can do, its a small file not yet a 100 kb.
can anybody tell me if there is something to do about it.

Increasing the frame rate is probebly the only thing that will help that.

i have tried that but i didnt help, thanks for your reply though, bye
