DIY Movie FX: Green screens for transparency

In this DIY video, I explain how to achieve a layered, transparent effect using a green screen and movie editing software (here, iMovie).

As an example I use my recent Halloween cover as Ursula the Sea Witch.

Be ensheathed in smoke! Be wrapped in flames! Appear as a ghostly vision in the sky! And other fun possibilities.
