Smooth animation involving multiple gradient objects

Hi,

 I have an animation that contains 3 rectangles with gradient fill on 3 
separate layers, overlapping each other(basically making a glassy capsule sorta

thing). In the beginning of the movie, the rectangles fade in, in more or less 
the same timeframe. The animation speed becomes choppy during this part of the 
movie, irrespective of the framerate I specify. (It's currently at 50)

 I also have some cacheBitmap() functions(for dynamic masking later on in the 
movie) taking place in the first keyframe. Tried removing them to test the 
speed, but no visible difference can be seen. 

 Would be great if someone could tell me how I could fix this problem.

 Thanks! :smile;

unfortunately, both a gradient and alpha transitioning are known to cause a 
slow down in rendering performance due to the extreme amount of calculations 
necessary in order to perform these redraws.  you could try using the 'use 
runtime bitmap caching' on all of those clips - or convert directly to 
BitmapData objects as CHAOS mentions.

Thanks a lot guys. I looked into the runtime bitmap caching issue, but it 
didn't seem to solve the problem. Although, there definitely was a noticeable 
performance increase when I did so. I enabled it for the background on which 
the rectangles were drawn. I haven't done the SVG thing though, as the 
gradients themselves were vector data, drawn in Flash. I could try grouping 
them and making them a single SVG file though -muses thoughtfully-
