Adding Motion Blur

To add motion blur:

1.   In the Shutter parameter group, select a suitable Shutter Time, depending on the amount of blur you wish to add. This sets the equivalent shutter time of the retimed sequence. For example, a shutter time of 0.5 is equivalent to a 180 degree mechanical shutter, so at 24 frames per second the exposure time is 1/48th of a second.

The larger the value, the more motion blur is produced.

A low Shutter Time value. A high Shutter Time.

Alternatively, you can enable Automatic Shutter Time to have Kronos automatically calculate the shutter time throughout the sequence. Note that this only produces motion blur when the retimed speed is greater than the original speed.

2.   Render the sequence to see the motion blurred result.
3.   If you can see that the motion blur has been created from a few discrete images, try increasing Shutter Samples. This results in more in-between images being used to generate the motion blur and so produces a smoother blur but takes longer to render.
4.   If you’re not happy with the results, proceed to Refining the Results.
