FLASH: smaller gif makes swf larger?

[Chris Burke]

Hi all.


I am making a Flash movie that includes alot of bitmaps and so I did a

little experimenting with image compression. Since the final images are

Jpegs, I was curious to see how much compressing files _before_ importing

into Flash did to save file size in the swf. I was very surprised to find

the following:


original gif saved from photoshop with no extra compression- 60k

same gif after compression in Gif Builder- 34k


Okay that much makes sense but then look what happens after importing these

files into 2 identical Fla files and then exporting the swf's:


swf containing 60k photoshop gif- 17k

swf containing 34k Gif Builder gif- 26K


The smaller gif made a larger swf. Why would would that be? I left all the

export dialog settings at default (Jpeg quality = 50.) Anyone have an

explanation for this? Is there a better way to save file size with bitmaps?
