Property Bin
This is the group that the script outputs. After the curve tool sample runs there are options to either match or deflicker the source/ filtering the output curve , mix, and range through keys.
Under the Hood
Inside the group there are switches to toggle between linked options. Notice everything is linked to a reference frame which might need to be rerun if the source's reference changes.
Remove Keyframe Display
The script will search for every node of the default tracker class and will switch the keyframe display flag to 'none'.
Only on render
Set a simple gui expression for the selected nodes to be enabled just during render.
