A nuke gizmo which injects single new frames into a clip using Optical Flow.
This script was originally used to solve a specific problem for a sequence on All Eyez On Me. It can easily be extended to other similar use cases.
It also serves as a good template for extending the Nuke user interface through new gizmos and key bindings.
Add everything in the gizmos folder to your .nuke/gizmos folder.
Repeat the same with the python folder from this project and your .nuke/python folder.
If you would like a button to immediately add a frame and add a keyboard shortcut, then append the contents of menu.py to .nuke/menu.py.
You will need a working Nuke installation with the Kronos plug-in.
