I experimented with one group of 4th graders today to try out my green screen stop motion animation monster idea. Now that we have 6 iPad document stands in the art room (thanks to a grant from ABC/25 foundation) we can easily set up animation stations under them. We tried using simple green construction paper and movable monster figurines under the document stand using the iMotion HD app. We moved the figure, took a picture and repeated. After 20 photos students saved a finished 2 second animation at 10 frames per second. We made a ditty (see my ditty post here) and watched the creatures dance over the music video using the green screen app by doInk.
Parents and students are going to give this lesson a try on the evening of May 19th. I modified the lesson so that it's a bit more streamlined now that Ditty allows you to import your own video. we no longer have to have a green screen step to overlay the ditty music/text to our animation. Here are the directions: download this pdf
Remember those iTunes + iPod Ads?
First, I loaded a green screen video into DoInk Green Screen App. I cropped and resized it to make sure only the figure and green screen showed in the viewfinder. Here is what it looked like before I applied the chroma filters.
When you enable the Chroma filter the green disappears by default. I moved the color dial over to red (the complementary color of green) and adjusted the sensitivity level until I found the sweet spot where the figure became a silhouette.
I exported this clip as a movie to make sure this effect is retained. Here it is below.
Then, I put the video with the new effect back into the Green Screen app and applied the default chroma filter effect which removed the green but kept the black silhouette. I added an image of a color below s that I could see silhouette.
This is the clip of created from above. The next step is to make decisions about the background and the figure's placement to create your video.
I wanted to try to recreate the iPod/iTunes ad with "iWords" in white over a solid color field. So, I used Phonto to make these three images to play behind my silhouette video.
As I was playing with this dancing silhouette effect I found myself wanting to combine them with words and music. A very simple way to achieve this was by using the Ditty App (see this previous post about ditty) to make a musical video from the words I typed. The movie exports as a square. So, I used one of the video layers in the green screen app to add a color so I can scoot the Ditty to one side of the viewing stage. This allowed me to add the dancing silhouettes on the top layer. I played with the sensitivity level until they became semi-transparent so that they can overlap the words without blocking them out.
Here is the video I created over a ditty with two layers of dancing silhouettes. Both layers have some level of transparency so they can overlap the words.
I have been doing a graphic design lesson inspired by the iTunes and iPod ads since 2007. I wrote about this lesson for School Arts Magazine and created tutorials for creating these effects for using the Mac Desktop app Keynote and the iPad using Superimpose. View this post.
Also I've posted a couple lesson ideas using the Ditty app. One was about adding green screen stop motion animation over a ditty.
See that post here.
The other lesson idea included using drawn or composed animation over a musical ditty. See my post about this here.
