Hello Barry,

for animations the Quartz node is the right one. Regarding to your new node:
There is variable in the input and output object called "label". If you set this variable to your input value it should work.
Or post your file with new node you want to create, that I can have a look.
In the attachment you will find a very experimental animation proposal. I don't know if storing pictures with the camera node under windows work.
The camera node saves single pictures that can be glued with mencoder or ffmpeg to a video.

Have a nice day
Karsten
