One problem when exporting scripted animations to video is that the overall animation is not finished at the last keyframe in main timeline. This could result in a video where the animation is cut before it is finished. I found out you can export your animation based on time rather than timeline frames.

This video tutorial from Layer Magazine explains how to export a scripted animation to Quicktime format (mov) directly from Adobe Flash CS. I don’t understand why they made such a long video tutorial because the only important thing is the export settings.

File > Export > Export Movie

Select the Quicktime format

Stop exporting “After time elapsed [time]“.

Watch is the result (1.4 Mb)

(I used Adobe Flash CS4 for this example but it works just as well in CS3).
