Adding realistic motion blur
Something that you probably have experienced while driving a car or traveling
by bus is looking out of the window and seeing the world moving so fast that
everything outside becomes blurred. The same thing happens when a camera is used
to record a movie, and this is because the frame or photograph doesn't represent an
instant of time. The time it takes to take a photograph or record a frame is defined by
the exposure's setting. In most situations, the exposure is enough to create a sharp
image, but there will always be some amount of motion blur. This is an important
concept to understand because when we first add the Motion Blur effect to the
movie, nothing happens.
Possibly, you are now trying the effect and seeing that nothing in the movie has
changed at all. Nevertheless, why don't you try to press the Play button and see this
effect in action? The following screenshot shows the difference in this effect being used:
The best way to see how the Motion Blur effect is affecting the clip or movie is
by dragging the time bar to the middle of the animation and tweaking the effect.
Motion Blur is one of the simplest effects to use, and you can rest your mind because
Lumion's team has developed this effect perfectly. The effect can only be perceived
when there is an animation, so if the camera doesn't move at all, no motion blur is
added. Also, the amount of motion blur is proportional to the camera speed, which
means that if the camera moves slowly, there will be a very small amount of blur in
comparison with a brusque camera animation.
