Camera - Blur Tab

Description
The Blur tab of the Camera node has settings relating to motion blur and depth of field.

Motion blur is only available in Terragen 2 with Animation and Terragen 3 with Animation. Depth of field rendering is only available in Terragen 3 (any edition).

Terragen 3 does not support object motion blur yet, only camera motion blur.

Settings:

  • Motion blur length: This is the total length of time (in frames) during which the camera's shutter is open, affecting how much motion blur is visible when the camera is moving. If motion blur length is 0 there will be no motion blur, regardless of how fast the camera is moving. If motion blur length is 0.5 (the default) the shutter will be open for exactly half the amount of time that the camera moves between one frame and the next. This is the most popular choice. It produces motion blur similar to a 180-degree shutter in a film camera, or a shutter of 1/48 second in a 24 FPS video. If motion blur length is 1, the shutter will be open for the full duration of time that the camera moves between one frame and the next. This is not possible in a real camera, but if it were it would be equivalent to a 360-degree shutter, or a shutter of 1/24 second in a 24 FPS video. Other values can be chosen, even those outside the range 0 to 1, but it is very unusual to go outside this range in animations. Note: To render motion blur in Terragen 3 with Animation, motion blur must be enabled on the render node, while In Terragen 2 with Animation you only need to ensure the camera's motion blur length is greater than 0. Turning off motion blur on the renderer is not quite the same as turning it off on the camera. Even with motion blur turned off on the renderer, it still uses the shutter window to calculate motion vectors (if output) and always renders an image that is centred in the shutter window so that the rendered image can be properly motion blurred in post, if necessary.
  • Shutter offset: Offsets the time (in frames) at which the motion blur shutter opens and closes. A shutter offset of 0 (the default) causes the shutter to open exactly on the frame number and close at frame + motion blur length. If, instead, you set shutter offset to -0.5 times the motion blur length (e.g. -0.25 shutter offset with the default motion blur length of 0.5), the motion blur will be centred on the current frame. Choosing the correct shutter offset may be important if Terragen renders need to be composited with tracked footage or output from other renderers.


Back to: Camera

A single object or device in the node network which generates or modifies data and may accept input data or create output data or both, depending on its function. Nodes usually have their own settings which control the data they create or how they modify data passing through them. Nodes are connected together in a network to perform work in a network-based user interface. In Terragen 2 nodes are connected together to describe a scene.
