Reducing imported frames file size

Lets take an example, I export some text blur effect from after effects and place into flash as sequencial jpgs,

Problem, it exports as 1.2 megs,

Soo I try and cut out everyother frame, note: that just make sthe animation faster but it does reduce the file size :smiley: . but now it;s to fast. Other than tweaking back in AE what other tricks does flash have ?
