To start off an editing project in Nuke, the first thing to do is read in the camera plate and work out the frame range you want to use during your editing. After this, you write out the scene in targa format and then read it back in to check it's worked.
I also used a sticky note in my node graph to have the camera information present:
Lens - Samyang Cine Lens 24 mm
Camera - Blackmagic Cinema Camera (2.5k)
ISO - 400
White Balance - 6000 kelvin
Shutter angle - 180 degrees
The next step was to remove the lens distortion. To do this, a lens distortion grid is used.
The lens distortion grid is filmed for only a few frames using the same camera and lens as the camera plate was made with.
Next, the lens distortion grid is read into the node graph and a lens distortion node is used on it.
Detect will place these yellow lines over the grid, and then solve will solve the distortion and the lines will turn green.
The node can now be copied over to the camera plate to remove the lens distortion from the camera plate.
