Thanks for the meme, edgyvfx!
Tired of matching grain manually? Me too!
DasGrain takes the pain out of the re-graining process by automatically adapting the plate grain to your comp.
For areas where the original grain doesn't work, you can generate a new grain that is based on the original grain.
Having a good degrain is crucial for this tool!

Please let me know how it works for you or if you have any questions. I'm always happy to help! :)
Unfortunately DasGrain doesn't work with Nuke Indie and Nuke NC due to their Python and Blinkscript limitations.
v1.8
- updated UI and many of the tooltips (let me know what you think!)
- fixed a fundamental bug in the per channel range script
- added a metadata knob to choose between plate and comp
- added a threshold, so that a sample has to contain at least 10 pixels to be used
- deleted the colorspace choice in the two colorspace knobs so on first load it will be set to whatever is the default space in your config rather than potentially error.
- updated Python scripts to be Nuke 13 compatible
- fixed and improved many minor things
special thanks to Erwan Leroy for his feedback!
v1.7
- added stereo option to generate different grain per view
- added colorspace menu
- couple of bug fixes and improvements that accumulated in the last year (aka I didn't keep track, but it's better now!)
v1.5
- added Help tab (with setup steps and Troubleshoot button)
- reordered, improved and removed some functions (check the tooltips and the updated video)
- bugfixes
- copy/pasting now roughly a million times faster
v1.4
- fixed bug (due to a missing link in the last version, only frame 0 was being analysed. This could've led to issues if degrained plate and plate had different start frames)
- minor improvements
v1.2
- Bugfixes
- tech improvements
- added luminance grain compensation and new DegrainHelper node
- layout improvements
