A brief description of FOV: Hold you arms out so that you are making an approximate 90-degree angle. Everything seen between your hands would be considered a 90 fov in the Anox world. Decrease that angle with your hands to 45-degrees. 45 fov. A knowledge of camera Lenses would be a great help to you here. FOV works in reverse compared to lenses. Ie: A wide angle camera lens, say a 10mm. Would be about a 110. A 300mm lens is like 20 FOV. Play around to get the desired look.
<P>
Subject A is ten feet from the camera. Subject B is 20 feet from the camera but directly behind subject A, but a little off to the side. If Camera A has an FOV of 90, Things would look normal. SEE BELOW.

Look at the FOV 20 Pic. Notice how Subject A and B look like they are really close to each other, and the Background also looks really close to the subjects.
<P>
We will want to make a new script to best show how FOV works.
<P>
Create a script, save it as "TUT_13"
<P>
Make it 1 camera looking at 1 point for 4 seconds. Play it just to see.
<P>
Go up to the FOV path right above the director path. Drop a node using CTRL. Now drop another. Move the First Node to 0:00, Move that second Node to 0:04
<P>
Select the second FOV Node by clicking on it(2D mode).
<P>
Hit 1 to edit. Move mouse up/down. Notice Value changing. THAT is your FOV value.
<P>
Make that second node have a value, of 50.
<P>
Play the script. The Shot Zooms in, without any camera movement. Change the First FOV node to 120. Now play that. Cool!
<P>
Return both FOV nodes to a value of 90.
<P>
Now select the second FOV node.
<P>
Hit 3 to adjust the velocity. Move the mouse up/down and look at the velocity graph. This is like adjusting the velocity of Roll.
<P>
When doing many camera cuts with the director path, you will have to double up your FOV nodes when doing hard cuts/changes to FOV. Above each director node you will usually see a 2 in the FOV paths.
<P>
FOV (I believe)is underused in most in engine cut scenes. And it truly is one of the BEST tools for composing shots. USE IT!!!! A Director once told me, “Know your lenses”. He was sooooo Right.
