Need new effect: pixel spread / erode-dialate / cleanplate

I don't see a lot of discussion around this topic and most After Effects compositors either use sub par methods or simply aren't in need for high end solutions. But for us being stuck in the ecosystem it is tremendously hard to perform high quality composite work without any form of pixel spread to do clean ups, edge extends and creation of clean plates from green screens.


These tools have been available in compositing packages like Flame, Fusion and Nuke for years already. The only thing we have is an immensly slow performing extend in Refine Hard Matte with tons of options we don't need and a range limit of about 1pixel. Their tools perform close to realtime and are able to smear the pixel information much much further.


Please consider implementing a very fast performing high quality pixel spreader that is able to take RGB information and spread it with different methods/modes via it's own layer's alpha/mask or external via the mask layer selection.


To understand what I'm talking about here are the tools in other software.

Flame (best implementation and featureset): https://youtu.be/d1q_4XTGaJk

Flame (same tool to do cleanplate in interpolate mode): https://youtu.be/DEg4jM11TQ8?t=203

Nuke EdgeExtend: https://youtu.be/_KhF9WnxITY

Fusion (least good algorithm/quality): https://youtu.be/wUSxUv9Y6Xc?t=593


Thank you.
