I've been googling without much luck for a list of downlevel browsers so that I can redirect to alternative content (not a poster image). But I can't find a list of which version of the browsers is the "fail" zone. I found a site that scores browsers, but it doesn't really let me know if my animation will work on them. I know IE8 and below, what else? What version does animation fail on Firefox, Chrome, Safari, Opera, etc, etc.
Any help would be appreciated.
I guess I could just detect for mobile and serve up the Adobe Edge Animation. If it is anything else, serve up the backup SWF.
Just not sure if that is the best way to go.
