Far right....4th button down.
Be aware, you will need to choose a compression, and the part that allows you to save just a part of your movie (a 14 min avi would be a tad big), has a bug that sometimes GREYS OUT the 'selection only' radio button....if you get this, you need to:
CANCEL OUT
CLICK INSIDE THE 'END TIME' SELECTION BOX (no changes needed)
SAVE AS AVI AGAIN
