2) Note that when your viewer is connected to "Rotopaint6" there is some edge banding with regards to data outside of the display window. 

Workarounds
Workaround 1: 

1) Create a merge node beneath the rotopaint node connecting the "A Pipe" to the Rotopaint, and the "B Pipe" to the reformat node. which will then remove the banding correcting the workflow. 

Result: 

This will allow you to rotopaint with the correctly overscanned footage. 


Workaround 2: 

1) Create a Reformat node which matches the initial size of the plate. 
 use the expression "Reformat1.bbox.w" and "Reformat1.bbox.h" in the expression of the width/height parameters within the new Reformat node. 

2) Apply your Rotopaint node and in it's Root Transform Tab use the following expressions in the Translate parameter. 
(Reformat1.bbox.w-Reformat1.width)/2 
and 
(Reformat1.bbox.w-Reformat1.height)/2

3) Create another Reformat node and paste the following expressions into its width and height parameters, 

Reformat1.width

Reformat1.height

Result: 

This will allow you to rotopaint with the correctly overscanned footage.

Expected behaviour
Nuke would allow the user to rotopaint with overscanned footage without presenting any errors. 

Actual behaviour
When rotopainting on overscanned footage Nuke's viewport
