when you see the army truck at night and well my question is how do you make the beams of light and how do you make the guys eye turn yellow but his face blue

The beams of light were made by grading the footage to be night and then masking where they wanted the beams to be to give the semblance of a headlight.

The color change was the hue shift filter masked to only cover the face and then the hue was changed to blue. They was another hue shift with a gleam effect was added for the eye.

I am not positive this is how it was done, it is only how I would have done it and what it looks like.

Multiwagon is pretty much on the ball here, especially with the blue soldier. Here's some more info on the truck:

Truck clip

Original:



The original was a very bright, sunlit shot. Not the most obvious candidate for day-for-night (indeed, Ashman didn't shoot this scene with that in mind).

Day-for-night:



A simple day-for-night filter was applied to the source clip in VisionLab Studio. Settings were tweaked slightly to get the desired appearance.

Headlights:



A new grade object was applied above the source clip. Masks were used to draw the headlights and animate them to match the movement of the truck. Then a gamma filter was applied to brighten the masked area. Gamma seemed to look more real than using a brightness filter.

Sky & Tinting:



An ambient light filter was also added to the headlight grade object, to make the light beams more yellowy-green, rather than the flashlight-style blue.

Finally, a second grade object was added. A rectangular mask was placed to cover the sky area, and a gamma filter was used again to darken the sky. This was a vital move, as the bright sky really gave the game away.

This post by itself would make a great VLab / CLab tutorial.
