I'm trying to create a presentation video that first begins with the audio from a Youtube audio source. At the beginning of the audio, I want a black screen for say 10 seconds. Then I want a stillframe of the beginning of a video source to be shown until a point in the music arrives. Then I want the video to play and fade at the end from a stillframe of the last frame in the video, back to a black color, with the music fading as well. I am kicking some things around but have been starting to go in circles. Could someone provide an overview of what is the best plan for doing something like this?
