I believe the standard way of handling this is to have three different versions of your movie.
low, normal and high quality (how you down the file size is totally dependent on you, could be dropping frames, could be lower rez, whatever). Which one gets loaded in can be determined by connection speed, I think this is pretty much the norm way of doing it, and while Anthony's solution is good in theory, I think it would be too much of a pain in the ars, not to mention a butt load of server-side processing every time a user loads your site. - Taka On Wed, Apr 1, 2009 at 6:44 AM, Paul Andrews <p...@ipauland.com> wrote: > "default your mechanism"? > > LOL "defeat your mechanism"? > > Paul > ----- Original Message ----- From: "Paul Andrews" <p...@ipauland.com> > To: "Flash Coders List" <flashcoders@chattyfig.figleaf.com> > Sent: Wednesday, April 01, 2009 1:36 PM > Subject: Re: [Flashcoders] FPS question > > >> Karl, >> >> Despite what has been suggested, this will still only have a chance of >> working work for some flash Movies written in a certain way.
