In this presentation, Aharon Rabinowitz shows you how to create this ocean scene in Adobe After Effects with only the tools found in AE - No 3rd-party plug-ins were used. He’ll also introduce you to a cool plug-in for creating realistic water. This was part of a presentation he gave on June 25, 2009 at After Effects New York.
Note from Aharon: This is not exactly a polished tutorial. The presentation I gave at AENY was not captured well, so I just sat down in front of my PC and re-recorded it straight through. There is no editing or audio cleanup here. Also, I drank a bottle of something called Soju about 15 minutes before I did it. I bet you won’t even be able to tell… mostly.
