Poser 5

Introduction

The motion blur option in Poser simulates how a camera takes pictures in real life. In Poser5, the two parameters “Open shutter” and “Close shutter” indicate how this virtual camera will take the picture, and at what points in the interval between the two main frames:

“Open shutter” indicates from when the camera starts to take the picture (i.e. the shutter opens);

“Close shutter” indicates when the camera stops taking the picture (i.e. the shutter closes).

Step 1 - The basics

Normally, when you render a frame, Poser will search for information for a motion blur in the next frame. However, when you render using the last frame in a series, Poser will simply use the previous frame to get the motion blur information. For this tutorial, I have always rendered from the last frame. Poser classifies the frames as follows:

The “Main frame” is the frame you are rendering;

The “Secondary frame” is the frame in which Poser will take the motion blur information

The timeline between two frames goes from 0 to 1. The value 0 (zero) is applied to the “Main frame” and the value 1 (one) is applied to the “Secondary frame”.

In practice, the “Open shutter” parameter indicates exactly when, during the interval between the main and secondary frame, the motion blur begins and “Close shutter” when it ends.

On the examples below, “Open shutter” is set to 0 (zero) while the “Close shutter” parameter goes through values from 0.1 through to 0.9.

Step 2 - How to use it in Poser5

Here's a concrete example of how to use motion blur in Poser. I used the Millennium Horse and a cyclorama background. In this case, the horse isn't blurred, only the background.

Create your scene in Poser5, in the first frame (picture above)

Change the number of frames to 2.
Go to frame 2 and “Add a keyframe”.
Go back to frame 1 and move the objects to be blurred by some small increment. In this example picture, I moved the Cyclorama.
Remember: the Main frame is after the Secondary frame (even if it does seem obvious, you'll probably make the mistake at least once)
