Hi

I’m working on some optimisation techniques to allow Flash for export my .swf in various file sizes.

I need to export the same .swf in a high quality and a lower quality version; so I normally just alter the JPEG quality manually.

But I was wondering if there is a method using AS3 that allows me to adjust the JPEG quality dynamically?

Is there something that works similar to this:

```auto
[SWF(backgroundColor=0xFFFFFF)]  

```

Cheers

Mark
