Installing GIMP GAP 2.6 on to GIMP 2.8

1. Get the (shown above) zip file from Google - Unzip this file.
2. Unzipping this file will give you an excecutable.
3. When you run the executable you will get a folder. 
4. Copy the files within to the plug-in directory of GIMP

I created the folder GAP - the files I needed were deep within directories created by the executable.

I copied these files into the GIMP plug-in directory.

When I restarted GIMP, I had a new menu item - "video".  This is GAP
