So now that I have animated all the various characters using the Puppet Tool in After Effects, I render all of them as PNG Image Sequences and import them all in Toon Boom Harmony. Then, I composite each one with its own electrical bubble, and work out a seperate motion path for each group. I also add final touches like sparkles and eye blinks, and a panning background (see video).
Once I’m happy with the way everything looks, I render the scene at 1920 x 1080 using Cineform Go Pro codec. The Cineform codec allows me to work at high resolution and maintain a very high image quality, while keeping the files to a manageable size. It is also gives you the ability to play the HD scenes in real-time within Adobe Premiere. You can find out more about Cineform here.
Once the scene is rendered, I bring it in Adobe Premiere and create a slow fade at the start to make it flow with the previous scene. I also add a vignette on top of the image. The vignette is a transparent PNG file, with slight shading on the edges, that covers the whole image. It is composited at the editing stage. Here’s a before and after example of the vignette:
