RELEASE NOTES

Performance Timers

Nuke's performance timers have been updated to give more accurate and detailed timing information on all

platforms. When performance timing is enabled, timing information is displayed in the Node Graph, and the nodes

themselves are colored according to the proportion of the total processing time that was spent in each one, from

green (fast nodes) through to red (slow nodes).

In addition, new python calls have been added to provide python access to timing information for individual nodes.

Alternatively, Nuke can now be run from the command line with the -Pf argument to obtain the full performance

profile for a render in XML format. Performance profiling can help you to debug slow scripts and find out where the

bottlenecks lie; this new feature was also used internally during the development of Nuke to help us target our

performance work most effectively.

Node Improvements

• Backdrop nodes now have a Z Order control, allowing you to set the layering of Backdrops within other

Backdrops. The Backdrop with the highest Z Order is placed at the front.

• All Nuke nodes with a Node tab in their properties now include lifetime controls allowing you selectively enable

and disable nodes according to frame range when use lifetime is enabled.

Miscellaneous

• The Text node now includes a Shadows tab, allowing you to add drop shadow to text in the Viewer, either as a soft

effect or regular node in the Node Graph. Drop shadows incude color, softness (blur), and shrink/expand

(dilate) controls.

The Text node's general performance has been improved, including enhanced caching.

• The Merge node now allows you to merge metadata as well as image data from selected or all inputs using the

metadata from dropdown.

• Nuke's Read node now includes a Metadata tab showing all metadata associated with the file(s) read in.

• BUGID 43858 - Preferences: The Preferences dialog has been edited for clarity and accuracy.

Nuke Studio 9 Features

Soft Effects

Soft effects are GPU accelerated effects, which can be added and manipulated directly in the timeline to perform

common tasks in real-time. Soft effects are applicable at sequence level, where they appear as a layer above track

items on the timeline, and at clip level where they appear as a colored line inside the associated track item. Sequence-

level soft effects apply their effect to whatever is beneath them in the timeline, for the duration represented by the

color bar in the timeline.
