jedypod / CornerPinOffset
Created Aug 3, 2019
CornerPin node with offset controls for each corner. Useful for tweaking cornerpin after all keyframes are baked (e.g. , from a tracker), in case you need to cheat the perspective or something else.

OpticalZDefocus is a physically accurate ZDefocus, which controls circle of confusion (coc) size based on lens geometry using the depth of field equation. Set your lens and film-back characteristics, your focus distance, and adjust the size of your bokeh with the aperture size, just like a real lens.


OpticalZDefocus is a physically accurate ZDefocus, which controls circle of confusion size based on lens geometry using the depth of field equation.

  1. Set your focal length and film-back characteristics to match the lens that shot your plate
  2. Animate your focus distance
  3. Adjust the f-stop to match the size of your bokeh to your plate

Just like a real lens! (And using the same math :P )

Nuke ffmpeg Render

Nuke ffmpeg Render

Writeffmpeg is a python script and a node that allows you to render from Nuke directly into ffmpeg. Instead of a 2 step process where you render from Nuke to a temporary image sequence that you then transcode using ffmpeg, this solution writes to a single uint16 cache tiff file and this data gets piped into ffmpeg.

I've included a little screen recordingto help demo how it works.

Type in 3D point coordinates, or use vertex selection in 3D viewer and click set to pick average of selected points, or set points to set all four points at once. \n\nYou can connect node output to scene together with your pointcloud or geometry and see where your points are located in 3d space. Double click any of them to move it in 3d space like any traditional nuke transform control. \n\nA matrix transform is also generated to be used with RotoPaint, SplineWarp and GridWarp nodes. If you are using matrix in GridWarp, points have to be in clockwise order, pick them one by one! \n\nCommand set points doesn't respect selection order! \n\nCheck out the demo video on my website!
