Blitz Defocus is a blinkscript-powered z-defocus node I wrote as I was struggling finding a tool that would simulate the bokeh streching and cat-eye occlusion happening on anamorphic and retro lenses. So I made one :)

It uses Jedypod's Optical Defocus algorithm so you can use real camera settings such as aperture, f-stop and focal.

Bokeh can then be squashed and cat-eye/barn-door occluded as they stray away from the optic center.

Some little extra features such as lens breathing, chromatic spread, bokeh noise and enhancements can also be found..

Would be amazing to have depth processed with this! :)

Just updated the tool, it should compute depth now :)

Great stuff Maxime! v2.0 does not have an extension and throws a whole lot of errors on pasting into comp.

Sorry, I will compile it properly as soon as I can put my hands on a license again..

If you replace '' with ' ' in i.e Sublime and change the extension to .nk it is working.

ok this reply looks off. In a text editor you see

< 0 x a 0 > (without spaces)

this you need to replace with a tabs

When I open it in notepad and search for that line it can't find it. Could you explain a little bit deeper? Would be awesome!

v3.0 fix is here

When I download it says v6.1, that's correct right? Thanks for making this one more awesome and awesome! Really neat gizmo! Good job!

Hey again! It doesn't recognize my depth pass even when I shuffle it out and use the depth input. Works fine in ZDefocus, Peregrine Labs and in Magic Defocus.

Thank you for the kind words , please try 6.3 :) depth pass should be coming from alpha channel though the depth input.

Hi! Thanks for the fast reply and fix! Will check it out! :D

In the gizmo it says v1.5 and the nk file is named v2.0. Then...

This is great! Would love a short tutorial or a written guide on all the features and how it works.

This might be the best defocusing tool out there. All the cat eye stuff has been done with some kind of array in the past, which introduced seams. And the Blink ones were very rudimentary. Nice job, combining the best of all worlds!!! Any chance you leave the Blink code unencrypted, so we can see and learn from it?

I will also leave some feedback for improvement:
The tool should be able to process (and output) the input resolution and not a specified format. Also, the boundingbox should not be discarded. Right now this also results in edge artifacts on the borders of the image and bokeh shapes "popping" into existence when the shot has motion. All this can be easily fixed though.

One more thing that could be improved:
Anamorph footage handling is a bit weird. I have to set the pixel aspect knob to 2 AND the anamorph value in the Filter tab to 0.5 in addition to selecting the anamorph format in the input format knob. Expected solution would be to remove the pixel aspect knob, as the format already contains a pixel aspect that we can use. (parent.format. pixel_aspect)
