Alt-] cycles to next node in the menu, while Alt-[ cycles to the previous node.

Tries to process at the current resolution as fast possible.

Tries to process as fast possible by first processing a 4:1 proxy and then full resolution.

Processes once the mouse or pen is released. This the default setting.

Silhouette does not process. If you place the cursor within the Viewer window and hit the Enter key, Silhouette will manually process any changes.

Controls editing in the Left/Right View.

When enabled, paint is added to both views simultaneously. When disabled, the left or right view is painted individually.

Only available once the Left/Right View is active, Stereo Split Mode determines whether or not the Left and Right Views are arranged horizontally or vertically.

When activated, Stereo Align uses a negative mode which inverts one of the views and mixes it with the other. This creates an embossed effect when similar image areas are not aligned.

With a layer selected, stereo sources can be aligned automatically by pressing Shift-Alt and clicking on the image feature that you would like to align. Shift-Alt will function whether or not the Stereo Align view mode is enabled.

Enable Stereo Align and drag on the Viewer to align the views.

When similar image features are perfectly aligned, you will see a solid gray color. The amount you move the view in Stereo Align mode is stored in the Stereo Offset parameter of the active layer which is set to animate by default. Animation of this parameter is needed for clips that contain depth changes.

There are four anaglyph viewing modes that you can choose from. The default mode is set using the Viewer > Anaglyph Mode preference.

The 3D Preview has a pop-up menu containing zooming controls and display selection choices. The pop-up menu is accessed by right-clicking in the 3D Preview window.

Zooms the image to fit into the 3D Preview.

Sets the image to a 100% zoom level and centers it in the 3D Preview.

Sets the 3D Preview to full screen.

A list of displays are available to choose from.

Preserves most of the color but causes retinal rivalry.

Creates a lighter image than a true anaglyph but results in more ghosting. No color is preserved.

Preserves less of the color but reduces the retinal rivalry.

Discards all of the red component from the original images and replaces it with a manufactured red channel derived from the green and blue components. The advantages are almost no retinal rivalry.

Interlaced mode requires a 3D monitor that uses interlacing like the Zalman passive display. Select the Left or Right Hardware Interlaced mode to determine which eye comes first--Left or Right. This needs to match up with how the monitor does the 3D effect.

1:1 keeps the image quality at full resolution.

2:1 lowers the image resolution by 1/2.

3:1 lowers the image resolution by 1/3.

4:1 lowers the image resolution by 1/4.

By default, Onion Skin is set up to display a mix to the previous frame.

Displays frames before the current frame.

Displays frames after the current frame.

Sets the Onion Skin mix value.

In Morph, it appears when View A/B is selected and in the Depth node, it is displayed when the depth map is viewed. Clicking the Blend Amount icon pops up a slider that can be moved from 0 to 100. You can also click and slide on the icon instead of using the slider.

Silhouette uses the OpenColorIO (OCIO) standard originally developed by Sony Pictures Imageworks for its color management. You can load custom color configuration files and custom LUTs, apply color space conversions, as well as use other controls for fine tuning. Silhouette includes a set of preset color profiles, plus you can configure and use your own by specifying one in the Color Management > OCIO Configuration preference.

For a more detailed explanation of OpenColorIO, including generating LUT’s and suggested workflows, please visit http://opencolorio.org/.

Sets the input colorspace of the scene. Silhouette automatically tries to determine the colorspace based on the data in the file and other information from the header. If a colorspace can’t be detected, linear will be selected.

Custom role names for different colorspaces can be assigned so it is obvious to artists which colorspace they should use. For instance, roles can be set up for compositing, color timing or matte painting. Artists still have access to the colorspace options they've always had, but now the roles can act as a quick way to understand and select the color workflow of a particular show.

Enter the role, family, and name of the role in the roles section of the OCIO config file located at <install_dir>\resources\ocio\silhouette-default.

If you are using a custom OCIO configuration with multiple Display options, the Display pop-up menu appears for you to choose the colorspace of the display. The default OCIO configuration only has one display option. Additional devices can be added in a custom configuration and will show up in this menu.

Sets the transform from the input scene’s colorspace to the display colorspace. Select a colorspace that matches your display device. You can select from sRGB, rec709 or None.

Applies a custom OCIO LUT to the scene. See the Appendix H - OCIO LUTS chapter for a detailed list of supported LUTs.

Select a LUT.

Clears the LUT list.

Adjusts the brightness of the image in F-stops. Gain is applied before the display transform.

Adjusts the gamma of the image. Gamma is applied after the display transform.

If you click on the numeric field to the right of the ROI label, the fields become editable. Just click in the field you want to edit, type in a number and press the Set button.

In the Silhouette/resources folder of your installation, there are two files: formats.xml and masks.xml.

You can add your own custom masks to the masks.xml file. The rectangle values are multiplied by the image width/height to figure out where the mask should be placed. For example, Safe Action is a 90% rectangle, so the border is .1, .1, .9, .9 (i.e. 10%, 10%, 90% 90%) of the image size.

You associate certain masks with certain formats by adding a “Mask” entry to the formats in formats.xml. You can add any number of masks to each format. These masks will be available in the mask selector in the Viewer, depending on the session format.

Go to the Viewer Rotation tutorial to see how it works.

Clicking on the Red, Green, Blue or Alpha buttons solo that channel as a gray scale image. The horizontal white bar above the RGBA buttons quickly toggles the display of the image back to full color mode.

Alt-R/G/B/A toggles the red, green, blue and alpha channels on and off.

Either press the Alpha button (to the right of the blue button) or the A key to cycle the state of the alpha display. Pressing once superimposes the alpha channel over the image. Pressing a second time displays the alpha channel over black. Hitting it again shows only the color image.

Shift-A toggles the View to Output, superimposes the alpha channel over the image and deactivates the Overlay. Pressing Shift-A again returns the Viewer to its previous state.

Alt+O toggles the view mode to Output and displays the alpha. Pressing Alt-O again returns the Viewer to its previous state.

The numeric entry box next to the RGBA buttons controls the opacity of the alpha channel when it is superimposed over the image.

You can premultiply the image in the Viewer by using Shift-0.

Go to the Using the RGBA buttons in the Viewer tutorial to see how it works.

Choose from one of the preset zoom percentages. 100% displays the image at its actual size at a ratio of one image pixel to one screen pixel.

You can also zoom the image using the scroll wheel on your mouse, the + or = keys to zoom in, and the - key to zoom out or press Space Bar-Shift and move the mouse up to zoom in or down to zoom out.

Either pressing the F keyboard shortcut or selecting Fit from the zoom pop-up window will display the image as large as possible within the Viewer window.

You can either press the H keyboard shortcut or double-click the middle mouse button to set the image to a 100% zoom level and center it in the Viewer.

Press Ctrl/Cmd-F to center the select object in the Viewer.

Go to the Viewer Navigation tutorial to see how to zoom and pan the Viewer.
