I've created a Flash web banner about 400kb in size that
plays fine until about halfway thru at which point the transitions
and animations seem to get noticeably slower. I've added a preload
script which loads the whole clip before playing and it still plays
with the same lag.
Also, it appears during playback within Flash that the Frame
per second (FPS) rate begins dropping from 12 fps after about 40
seconds and ends up at about 5 fps. Can you make the FPS rate stay
A. Flash is a processor intensive product and depending on
the processor and graphic animation you are performing you could
have an issue. Try using gettimer() functions to detect beginning
and end of slow points to isolate possible code such as transitions
B. Unnecessary code running that does not show up in display.
C. Did you perform a bandwidth analysis?
This is done with
1. File->Publish Settings select Flash tab and checking
Generate Size Report. You get data in the Output window when you do
Control->Test Movie and a text file in the publish directory.
2. This is done in Control->Test Movie and once running
with View->Bandwidth Profiler; View->Download Settings;
