Cropping elements off stage

When you export to video format, the file is cropped to the stage size.

Hi mate, 

Or you just mask the stage as shown in our Movie Template: http://flash-powertools.com/edapt-movie-template-free-download/

which you can download to see how the file is structured.

Good luck!

The clip content feature is just an author time conveniance. To fix the issue you see you need to change the stage scale mode. The default one is called "showAll", and it intenionally reveals the content off the sides of the stage. It's extremely useful when making mobile apps that have to work on a wide range of screen ratios.

To prevent the side items from appearing you can use "noBorder". That will have the opposite effect, in that as you make the browser window be taller or wider, the stage area contents will get cut off. You can work around that either by laying everything out with code, and using "noScale", or by designing your scene so that the important parts are far enough from the edges that they will remain visible for most window ratios.

The code to use is this:

stage.scaleMode = "noBorder";

Put that into the Actions panel in frame 1 of your timeline.
