The challenge is on. You are to make an amazing two-minute video in under two hours. The subject can be anything you like. But here's the catch... you aren't allowed to shoot video.
First, gather some pictures and Photomosh them, saving them not as images but as gifs/webm.
Find a royalty free soundtrack that will underpin your movie.
Then, spend half an hour playing with Adobe Spark, or Renderforest or Lumen5 to see if they can be of use to you.
And finally, you can bring all your pieces, the fragments, the pictures, the audio, the generated movies together in the excellent Clipchamp.
Here are some places to get pictures and sounds. Go get a little collection of maybe ten or so images perhaps. They might have a theme, or tell a story. It's up to you.
Think about how long you are aiming your video to be. Is it one minute, or five? It would be good to find a backing track that was roughly that. Maybe you could use some sound effects for certain parts of your video?
