User Manual

 SubView type: (These aren’t available in 3D viewers.) Clicking the icon itself enables
or disables the current “SubView” option you’ve selected, while using the menu
lets you choose which SubView is enabled. This menu serves one of two purposes.
When displaying ordinary 2D nodes, it lets you open up SubViews, which are viewer
“accessories” within a little pane that can be used to evaluate images in different ways.
These include an Image Navigator (for navigating when zoomed far into an image),
Magnifier, 2D viewer (a mini-view of the image), 3D Histogram scope, Color Inspector,
Histogram scope, Image Info tooltip, Metadata tooltip, Vectorscope, or Waveform
scope. The Swap option (Shift-V) lets you switch what’s displayed in the viewer with
what’s being displayed in the Accessory pane. When displaying 3D nodes, this button
lets you turn on the quad-paned 3D viewer.
 Node name: The name of the currently viewed node is displayed at the center of the
viewer’s title bar.
 RoI controls: Clicking the icon itself enables or disables RoI (Region of Interest) limiting
in the viewer, while using the menu lets you choose the region of the RoI. RoI lets you
define the region of the viewer in which pixels actually need to be updated. When a
node renders, it intersects the current RoI with the current Domain of Definition (DoD) to
determine what pixels should be affected. When enabled, you can position a rectangle
to restrict rendering to a small region of the image, which can significantly speed up
performance when you’re working on very high resolution or complex compositions.
Auto (the default) sets the region to whatever is visible at the current zoom/pan level in
the viewer. Choosing Set lets you draw a custom region within the frame by dragging
a rectangle that defaults to the size of the viewer, which is resizable by dragging the
corners or sides of the onscreen control. Choosing Lock prevents changes from being
made to the current RoI. Choosing Reset resets the RoI to the whole viewer.
 Color controls: Lets you choose which color and/or image channels to display in the
viewer. Clicking the icon itself toggles between Color (RGB) and Alpha, the two most
common things you want to see (pressing C or A also toggles between Color and
Alpha). Opening the menu displays every possible channel that can be displayed for
the currently viewed node, commonly including RGB, Red, Green, Blue, and Alpha
(available from the keyboard by pressing R, G, or B). For certain media and nodes,
additional auxiliary channels are available to be viewed, including Z-depth, Object ID,
Material ID, XYZ Normals, and so on.
 Viewer LUT: Clicking the icon itself toggles LUT (LookUp Table) display on or off, while
the menu lets you choose which of the many available color space conversions to
apply to the viewer. The top five options let you choose Fusion controls that can be
customized via the Edit item at the bottom of this menu. The rest of this menu shows all
LUTs installed in the LUT directory to use for viewing.
By default, when using DaVinci Resolve, the viewers in the Fusion page show you the
image prior to any grading done in the Color page, since the Fusion page comes
before the Color page in the DaVinci Resolve image processing pipeline. When you’re
working on clips that have been converted to linear color space for compositing, it is
desirable to composite and make adjustments to the image relative to a normalized
version of the image that appears close to what the final will be. Enabling the LUT
display lets you do this as a preview, without permanently applying color adjustments
to the image.
 Option menu: This menu contains various settings that pertain to the viewers in Fusion.
–
Snap to Pixel: When drawing or adjusting a polyline mask or spline, the control
points will snap to pixel locations.
–
Show Controls: Toggles whatever onscreen controls are visible for the currently
selected node.
