After Effects – Green Screen and PixelPoly (Gr 5-6)

So now the Gr5-6s have a little experience with the After Effects workflow and are developing their understanding of keyframes, it’s time to have a bit more fun. I came up with the idea where they could blow themselves up. Imagine you see a robot, you beg for your life, it shoots you and you explode. See the video below.

Such a simple and fast video requires a lot of work in After Effects to pull off. I want to make a disclaimer right away – I know the video quality is rubbish. I had to use an iPad which was all we had to use for video at the time. The green screen corner I had painted in my room is also problematic because of either low or uneven lighting. This can make a big difference in keying out the green from the video.

In any case, this project took up three sessions. Session 1 was filming each group on the green screen, getting them to upload that video from the iPad to their Google Drive account and then importing that video into After Effects. Like the last project, I already had a After Effects project set up for them, so they just needed to open it and save it with their names as their own copy. From there, the students learned how to key out the green and clean it up as best they could. As I said, because of the lighting issues, results were quite varied.

Session 2 involved the students creating the explosion effect with the sound and Session 3 was about generating the laser effect.

Here is my video for teaching Session 1 – keying the green screen footage.

And my video for teaching Session 2 – creating the explosion effect

And finally my video for teaching Session 3 – creating the laser beam

I’ve also added again the video I used in the last After Effects post about exporting the finished composition to a video file.

As I mentioned before, After Effects is challenging to use, so if you are game like me and want to give your kids a go with it, there are several resources I can point to.

First, the Adobe Education Exchange is a must in finding courses, lesson plans and all sorts of teacher goodies. All completely free of charge. I highly, highly, highly recommend it. At the time of writing, there are close to 1000 hits when it comes to projects and lessons you can look at for After Effects – including Up and Running with Adobe After Effects CC.

If you want some simple starter activities, have a look at Adobe’s Learn and Support area for After Effects. There are some excellent tutorials and videos here for you to have a look at, with excercise files to play along with.

If you want something even more in depth, have a look at Lynda.com – a brilliant site for self paced courses. Check to see if your institution gives you free access to Lynda. My public library gives library members free access as well. Otherwise, it does cost to access the course library – but you can sign up for a free 10 day trial. Well, well worth it!

Finally, if you’re more of a book person, I love Adobe’s “Classroom in a Book series”. It comes with lots of projects, technical information for lay people and a host of excersise files to play with. The latest edition, at the time of writing, is Adobe After Effeects CC Classroom in a Book (2015 release).

The Gr 5-6s will be doing one final mini project where they combine their two videos for their portfolioin Premiere Pro. It’s a very simple thing to do, so I don’t think I’ll do a post on it. For this year, that’s then the last project for the senior grades. I’ll be posting a reflection during the holidays.
