Test SWF Movies

Once you have created your Flash Movie, you need to check how long it will take to download!

Test your Movie for downloading. (Control > Test Movie)

Set download Speed

Check Bandwidth Profiler and Streaming

Check how the movie downloads to see if you need to create a preloader

Review the following:

Codecs, FLV, MPG, MOV

Movie too big? Create a pre-loader using if then else capability of actionscript!
Example: Create a simple animation that lasts 20 frames. On frame 21 add an action script that checks to see if the rest of your movie is completely loaded. If your movie uses 500 frames, your script would look like this

if (_framesloaded=500) {

gotoAndPlay ("Scene1","22");}
else {
gotoAndPlay ("Scene1","1"); }

Newground's Flash Help has a preloader you can use for your site if you don' t like the one you created!
