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.

Subsamples Parameters
- Subsample Amount
- 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.
- Subsamples Factor
- Subsample Factor has affects to how many the subsamples must it to compute. If is the value of Subsample Factor high, the smudge is finer, but rendering is long, as it involves much more computations.
Samples
| From Subsample Start 0 to Subsample End 1 | From Subsample Start 1 to Subsample End 0 | |
|---|---|---|
| 0f–0f |

| 0f–24f | 
|
