We have now learned masking both static and animated. I don't know if there is a technique to fade out the mask (turns out you can do it with scripting, once you convert the final frame of the mask into a movie clip. I need to learn more to try it). I couldn't figure it out so, in the first example, "FishScales," I replaced the last frame with a screen capture of the frame, converted that to a symbol, and then motion-tweened it to alpha 0% to reveal the background. It seems smoother in the final product.
In the second, "Salmon," I tried a different approach to the transition from the mask to a bitmap. I duplicated the background image of the fish and positioned it on a layer above the mask and had it fade in before the end of the mask. The background fish was completely replaced by the second one by the time it reached 100% alpha. The transition is still a bit jarring and not as smooth as with the FishScales approach.
