My fifth graders all contributed to one rotoscope animation segment that became part of this international animation collaboration. You can see ours during the first segment beginning at the 25th second. I guess you can say we help get the rotoball rolling. We are so pleased to be a part of such an amazing video. Thank you David Gran, Art Teacher, Shanghai, China.

I was asked today by Melissa, art teacher in a Cincinnati Jr. High, to relay my experience rotoscoping with my 5th graders on iPads.
I had mapped out a plan a long while back as to how I was going to approach this lesson and found that I did made some modifications along the way.

1. Students created a short video (Learned that adding transitions like fading out doesn't translate well when student did a contour line drawing-skip that next time)
2. Convert the video to jpgs (try using MPEG Stream Clip (free download) Here is my  screencast showing you how to do this.
3. Dropped the images into Dropbox (They were all 001-335 already so everything was in order)
4. Assigning images to students (I was taking too much time with this process. I should have just written the image numbers on tickets and have a bucket for them to grab from. Then later when I needed to reject an image, which I did many times on my quality control checks, I would just put the number back into the bucket)
5. Import into layer in Brushes (yes----but they draw in a layer over the photo then hide the photo under the white layer before the turn it in. If they followed directions then it worked. If they drew on the photo layer. they wasted their class time. UGH!)
6. Uniform protocol (We all chose solid black lines size 3, full opacity and decided how to deal with difficult parts of the video together)
7. Turned back the art via email (They wrote their name and image number under the drawing in digital ink in Brushes and used the Subject line of the email to tell me again their name and image number) 
8.Collect the images (I grabbed the images from email and renamed them by number and artist ie, "007jessica" Everything neatly stacked up in the folder. So I dropped them all into imovie with .2sec no effects and made the movie. It was too slow at first. So I exported it-reimported it and used the speed adjustments to make it faster. I tried gifninja to make an animation of some in-progress images.
9. Tweak and turn in (we were able to submit it to Rotoball 12 after we cropped it to 15 seconds and added the ball in and ball out as required)
