Drawing API, and Video

This has a few parts. I want to know if it’s possible to use the drawing API along with dynamic Quicktime, FLV and images loaded behind them at runtime, save the data in some way and then load it back again.

  1. Is it possible to save what a user draws with the drawing API so that it can be saved to a database and retrieved at a later time? How about text annotations?

  2. Is there a way to make an eraser tool for the Drawing API?

  3. Can you save a composite of what’s currently displaying in the flash player such as a FLV with drawing API lines on top, or an image with drawing API lines on top?

  4. Any tutorials on saving keyframes of external video or FLV files? Advanced Video Capabilties with Flash 8? I rememebr seeing something from Macromedia or somewher eelse and can’t find it for the life of me.
