AS3 Error #1009, random line errors
This usually means something hasn’t been instantiated yet, and you’re trying to call on something that doesn’t exist or have it’s values yet. I kept getting related errors for line numbers that seemed obviously OK. My problem was that I had moved my super() call to below a couple other lines of code.
Use sin() to oscillate waves in After Effects
This expression will make something oscillate back and forth on the x axis, such as “puppet show” waves
amplitude = 10;
frequency = 3;
temp=amplitude*Math.sin(time*frequency)+amplitude;
// add the result to the current x pos
temp=temp+transform.position[0];
//plug the new x into slot 0. y is currently left unchanged
[temp, transform.position[1]]
Permutations of 1920×1080 for perfect scaling at 1.7(7)
Here’s a list of good sizes to use when scaling down a 16:9 image:
Also note that Adobe Media Encoder doesn’t allow odd numbers in it’s dimensions for mp4 files. It will round your dimensions and add black pixels to the edge of the movie. For mp4s in AME, only use dimensions where they’re both even numbers (e.g. INVALID dimension: 464 x 261)

Embedded FLVPlayback inappropriately taking over screen when SWF goes to fullscreen
Because the FLV player was manually placed in a movie clip, I used:
myFLVPlaybackInstanceName.fullScreenTakeOver = false;
However, if the player is generated at runtime via code, use:
// In main class constructor:
primaryDisplayObject.stage.addEventListener(Event.ADDED,
displayObjectAdded, true);
// A little later in the main class:
// Listener when any display object is added to stage.
private static function displayObjectAdded(evt:Event):void {
if (evt.target is FLVPlayback) {
evt.target.fullScreenTakeOver = false;
}
}

SWFObject hair-puller
I kept having unknown issues with my SWF Object html not working. Finally, I discovered that the permissions for the swfobject.js file were not allowing the .js to load.
Validate XML documents with Firefox
Open an XML file directly in Firefox to validate it’s structure. Sometimes it helps me catch a nasty invisible that is causing a parsing error before it mysteriously messes with the Flash trying to use it.
IE turns into a black screen when reloading or refreshing page with Flash
We had a stubborn bug in Internet Explorer where all of the Flash content would go black if you reloaded/refreshed the page. The issue turned out to be a dynamically adjusted mask that for some reason on reload (but not initial load) would cause the whole swf to crash. Specifically, I was using AS3 to resize the global screen mask to stage.stageWidth (& height). For some reason IE didn’t like it but all other browsers were unaffected. Once removed, it worked fine. This may have something to do with the stage being resized before it has been properly initialized, but I haven’t tested it.
Increase animation of rollout sheets in OS X
I hate how slow the Mac OS sometimes seems because of the “pretty” things it provides.
In Terminal, type:
defaults write NSGlobalDomain NSWindowResizeTime .001
This speeds up the “roll-out” animation of many dialog boxes and effects across various apps.
