Camera Shake [CSh]

Image:Icon_CameraShake.png

This tool can simulate a variety of Camera Shake style motions from organic to mechanical. It is not the same as the Shake Modifier, which generates random number values for tool controls. See the Connections and Modifiers chapter for more information about the Shake Modifier.

The Camera Shake tool concatenates its result with adjacent transformation tools. For more information on concatenation, consult the Transformations chapter.

Contents




Controls Tab


Deviation X And Y

These controls determine the amount of shake that is applied to the image along the horizontal (X) and vertical (Y) axis. Values between 0.0 and 1.0 are permitted. A value of 1.0 generates shake positions anywhere within the boundaries of the image.


Rotation Deviation

This determines the amount of shake that is applied to the rotational axis. Values between 0.0 and 1.0 are permitted.


Randomness

Higher values in this control cause the movement of the shake to be more irregular or random. Smaller values cause the movement to be more predictable.


Overall Strength

This adjusts the general amplitude of all the parameters and blends that affect in and out. A value of 1.0 applies the effect as described by the remainder of the controls.


Speed

Speed controls the frequency, or rate, of the shake.


Frequency Method

This selects the overall shape of the shake. Available frequencies are Sine, Rectified Sine and Square Wave. A Square Wave will generate a much more mechanical looking motion than a Sine.


Edges

This determines how the Edges of the image are treated.


Black

This causes the edges that are revealed by the shake to be black.


Wrap

This causes the edges to wrap around (the top is wrapped to the bottom, the left is wrapped to the right, etc.).


Duplicate

This causes the Edges to be duplicated causing a slight smearing effect at the edges.


Invert Transform

Select this control to Invert any position, rotation or scaling transformation. This option might be useful to exactly removing the motion produced in an upstream Camera Shake.


Flatten Transform

The Flatten Transform option prevents this tool from concatenating its transformation with adjacent tools. The tool may still concatenate transforms from its input but it will not concatenate its transformation with the tool at its output. See the Transformations chapter earlier in this manual for details on concatenated transformation.

Filter Modes

Nearest Neighbor

This skips or duplicates pixels as needed. This produces the fastest but crudest results.

Box

This is a simple interpolation resize of the image.

Linear

This uses a simplistic filter, which produces relatively clean and fast results.

Quadratic

This filter produces a nominal result. It offers a good compromise between speed and quality.

Cubic

This produces better results with continuous tone images but is slower than Bi-Cubic. If the images have fine detail in them, the results may be blurrier than desired.

Catmull-Rom

This produces good results with continuous tone images which are resized down. Produces sharp results with finely detailed images.

Gaussian

This is very similar in speed and quality to Bi-Cubic.

Mitchell

This is similar to Catmull-Rom but produces better results with finely detailed images. It is slower than Catmull-Rom.

Lanczos

This is very similar to Mitchell and Catmull-Rom but is a little cleaner and also slower.

Sinc

This is an advanced filter that produces very sharp, detailed results, however, it may produce visible `ringing' in some situations.

Bessel

This is similar to the Sinc filter but may be slightly faster.

Window Method

Some filters, such as Sinc and Bessel, require an infinite number of pixels to calculate exactly. To speed up this operation, a windowing function is used to approximate the filter and limit the number of pixels required. This control appears when a filter that requires windowing is selected.


Hanning

This is a simple tapered window.

Hamming

Hamming is a slightly tweaked version of Hanning.

Blackman

A window with a more sharply tapered falloff.

Kaiser

A more complex window, with results between Hamming and Blackman.

Most of these filters are useful only when making an image larger. When shrinking images, it is common to use the Bi-Linear filter, however, the Catmull-Rom filter will apply some sharpening to the results and may be useful for preserving detail when scaling down an image.

Tips for Camera Shake (edit)

Shaky Text with Camera Shake

Below is a simple example of how to achieve the `shaky text' effect using the Camera Shake tool.

  • Start a new composition and add a Text+ tool with medium size text.
  • Connect the output of the Text tool to the input of a Camera Shake tool (located in the main Tools>Transform menu).
  • Display the tool in one of the views and expand the Camera Shake tool's controls.
  • The default settings are quite good as a starting point, so leave the controls alone for now.
  • Set the Current Frame to frame 0.
  • Animate the Overall Strength slider by right-clicking on the control and selecting the Animate option.
  • Set the Overall Strength value to 0.0.
  • Advance to frame 9 and set the Overall Strength value to 0.75.
  • Advance to frame 49 and set a key frame for the Overall Strength to 0.75.
  • Advance to frame 59 and set the Overall Strength value to 0.0.
  • Open the Camera Shake tool's common controls Tab by clicking on the nuclear symbol in the controls.
  • Enable the tool's Directional Blur by checking (clicking on) the Directional Blur checkbox.
  • Set the Directional Blur Quality value to 5 for smoother results.
  • Set the Render Range to start at 0 and end at 59.
  • Create a Flipbook preview (note the size available according to available memory).
  • Remember that all of the nice details will only show up when the Hi-Q Preview option is enabled. Experimenting with the various parameters will produce different results. Increasing the Randomness and Deviation values can create some pretty violent results.
