Exporting Flash Movies to other formats
Just a quick one for those of you pulling your hair out. Movie clip animations don’t work when exporting Flash to other formats or importing .swfs into external applications, like Quick Time, After Effects or image sequences.
Movie clips themselves are fine, but they only display the first frame. The secret is to convert all your movie clips to graphic symbols! They work just fine. If you scrub the play head through your timeline, whatever you see will probably render okay elsewhere.
If you are creating a Flash Banner and want to export frames to animated gifs it is a good idea to build your animation entirely on the root timeline, or use graphic symbols. It will save you a lot of hassle later.
