Feed values into Crop Node (Left, Right, Top and Bottom) I am a noob at doing this, as I started very recently.
I tried cropping every frame in a video file to my mouse cursor. So, I searched up the Track Position Node and tracked the position of my cursor slowly moving.

Then, I made a Math Node tried outputting variables for my Crop Node's Left, Right, Top and Bottom values. However, there are no input nodes other than Image.

Is there any way I can feed a value output into the Crop Node's Left Right, Top and Bottom?
QUICK UPDATE

Found a workaround, just used an array of nodes that had x and y inputs


Going to crop manually later using another crop node
