http://www.manbirdproductions.com Here is a simple breakdown I did of the UFO sighting from inside a car shown on my 'Of the Third Kind' video. This was my first attempt at using purely 2-D elements. Far more advanced usage of this technique can almost replace 3-D elements all together. But they have to be used with caution and moderation!
This was done entirely in Adobe AfterFX. For the full video, check out the 'Of the Third Kind' video on my Youtube page.
