I am having this issue with Flash CS5 Mac version:
After making an animation, I export movie as Quicktime. When I view this movie, the animation leaves trails of color when an object moves across the screen, leaving behind little bits of color too. This does not happen when I export a SWF, but it does happen when I export a Quicktime movie. I export using Quicktime, so I can then I can export it into a flv in Adone media encorder.
Why does this happen? Any ideas?
Thank you very much.
This has been happening for years, looking for a decent solution myself.
