About Motion Blur Layer

Blur is a graphical effect that aims to imitate an unfocused image. In a photography context blur can occur when the focal point of the lens is not at the right position of the target of the photograph. Also blur can have other origins. Blurs can happen as the result of a poor exposure during its recording (too long exposure time for a large movement of the object or a high movement of the recorder). Also blurring occurs when you use a very wide aperture (f4). In that case the objects that are out of focus are very blurred compared to the situation where the aperture is fully closed (f22).

In a graphical context, blurs are effects that imitate those situations (with more or less success). Motion Blur Layer allows to simulate the blur of picture, that arises by movement.

Specific parameters

The parameters of the Motion Blur Layer are:

Name Value Type
Type time icon.png Aperture 0f time
Type real icon.png Subsamples Factor 1.000000 real
Type integer icon.png Subsampling Type Hyperbolic integer
Type real icon.png Subsample Start Amount 0.000000 real

Subsamples Parameters

Subsamples Factor 
Subsamples Factor affects the number of subsamples to be computed. Using a high value the smudge is finer, but the rendering is longer as it involves much more computations.
Subsampling Type 
  • Constant
  • Linear
  • Hyperbolic
Subsample Start Amount 
If is value of Subsample Start Amount 0, has not any blur on start. Otherwise motions of objects from lower layers begin as a smudge.
Subsample End Amount 
If is value of Subsample End Amount 0, is last state of the objects from lower layers without any blur.

Samples

  From Subsample Start 0 to Subsample End 1 From Subsample Start 1 to Subsample End 0
0f–0f Motion blur 0-1 aperture 0-0f.gif
0f–24f Motion blur 0-1 aperture 0-24f.gif Motion blur 1-0 aperture 0-24f.gif
24f–24f Motion blur 0-1 aperture 24-24f.gif Motion blur 1-0 aperture 24-24f.gif
24f–0f Motion blur 0-1 aperture 24-0f.gif Motion blur 1-0 aperture 24-0f.gif
Note 
Rows in table – Aperture value from begin (0 frame) to end (120 frame).
Columns in table – Subsample Start Amount value and Subsample End Amount value
