![]() ![]() Where to get the optional foreground mask to use when estimating motion: Note:The default value works well for most sequences. ![]() Lower values may miss local detail, but are less likely to provide you with the odd spurious vector, producing smoother results. Higher values allow you to accurately match similar pixels in one frame to another, concentrating on detail matching even if the resulting motion field is jagged. Sets the strength in matching pixels between frames. Note:High detail vectors take longer to render, but can improve the results you get from the VectorDistort node. The default value of 0.3 is sufficient for sequences with low detail and movement, but you may want to increase the detail to improve the vector quality in some cases. See Nuke 15 Release Notes for more information on the GPUs Nuke supports. You should also select this if you wish to render from the command line with the -gpu option. Note:Enabling this option with no local GPU allows the script to run on the GPU whenever the script is opened on a machine that does have a GPU available. When enabled, rendering occurs on the Local GPU specified, if available, rather than the CPU. Note: Selecting a different GPU requires you to restart Nuke before the change takes effect. ![]() You can select a different GPU, if available, by navigating to the Preferences and selecting an alternative from the default blink device dropdown. it was not possible to create a context for processing on the selected GPU, such as when there is not enough free memory available on the GPU.no suitable GPU was found on your system.Use CPU is selected as the default blink device in the Preferences.The sequence from which to generate motion vectors.ĭisplays the GPU used for rendering when Use GPU if available is enabled. Inputs and ControlsĪn optional matte of the foreground, which may improve the motion estimation by reducing the dragging of pixels that can occur between foreground and background objects. ![]() exr format, which are then used to drive the VectorDistort or VectorCornerPin nodes as part of the Smart Vector toolset. The SmartVector node writes motion vectors to the. ![]()
