Camera Shake [CSh]

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.

Controls Tab

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.

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

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.

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 controls the frequency, or rate, of the shake.

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.

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.

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.

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.

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.
