User Manual

When the Saver node is set to DPX, it’s important to understand the reason for the
Bypass Conversion > Data is Linear option. When saving log data into a DPX, and not
using the Saver’s node’s own lin-log conversion (that is, Bypass Conversion is checked),
the Data Is Linear option should be off. This indicates whether the reason for checking
Bypass Conversion is because the data is linear, or whether it’s already log.
If Data Is Linear is enabled, then the DPX is marked in its header as containing linear
data. In turn, that means that when the DPX is loaded back into Fusion, or into other
apps that evaluate the header, those apps think the data is linear and do not perform
any log-lin conversion.
Common Controls
Settings Tab
The Settings tab controls are common to both Loader and Saver nodes, so their descriptions
can be found in “The Common Controls” section at the end of this chapter.
Clipping Mode
This menu, sometimes considered source image clipping, defines how the edges of the image
should be treated.
 Frame: The default Frame setting clips to the parts of the image visible within its visible
dimensions. It breaks any infinite-workspace behavior. If the upstream DoD is smaller
than the frame, the remaining areas in the frame are treated as black/transparent.
 None: This setting does not perform any source image clipping at all. This means that
any data that would normally be needed outside the upstream DoD is treated as black/
transparent. Be aware that this might create humongous images which can consume a
considerable amount of disk space. So you should use this option only if really needed.
For more information about ROI, DoD, and Infinite Workspace, see Chapter 8, “Using Viewers”
in the Fusion Studio Reference Manual or Chapter 60 in the DaVinci Resolve Reference Manual.
Save Alpha to Color
When enabled, this control causes the Alpha channel to be saved into the color channels as a
grayscale image. This completely overwrites any existing color information.
Color Space Type
This menu is used to set the Color Space of the output file so you could, for example, color
space convert images from linear to Rec709, etc., thereby delivering linear EXRs, 709
Quicktimes, etc.from a single source. The images are not being converted in the Comp, only in
the images saved to disk are converted.
 Auto: Passes along any metadata that might be in the rendered image.
 Space: Allows the user to set the color space based on the output format.
Curve Type
This menu is used to select a Gamma curve of the rendered file. Once the gamma curve type is
set, you can choose to apply the curve for output.
 Auto: Passes along any metadata that might be in the incoming image.
 Space: Allows the user to set the gamma curve based on the selected file format.
 Log: Displays the Log/Lin settings, similar to the Cineon Log node. For more detail on
the Log settings, refer to Chapter 39, “Film Nodes.”
