COMFYUI Nodes for procedural masking, live composition and video manipulation

JOVIMETRIX IS ONLY GUARANTEED TO SUPPORT COMFYUI 0.1.3+ and FRONTEND 1.2.40+

IF YOU NEED AN OLDER VERSION, PLEASE DO NOT UPDATE.

SPONSORSHIP

Please consider sponsoring me if you enjoy the results of my work, code or documentation or otherwise. A good way to keep code development open and free is through sponsorship.

HIGHLIGHTS

30 function BLEND node — subtract, multiply and overlay like the best

Vector support for 2, 3, 4 size tuples of integer or float type

UPDATES

DO NOT UPDATE JOVIMETRIX PAST VERSION 1.7.48 IF YOU DONT WANT TO LOSE A BUNCH OF NODES

* MIDIFilterNode

* MIDIFilterEZNode

Migrated to Jovi_MIDI

ALL STREAMING NODES:

* GLSL CONICAL GRADIENT

* GLSL DIRECTIONAL WARP

* GLSL FILTER RANGE
