Compv2coreNeeds full input

Overview

EXPERIMENTAL — still being built. Removes an object by pulling the TRUE background from the frames where it is visible: every masked pixel is filled from other frames warped through a BS_VectorBake, taking a confidence-weighted median so flicker and passers-by drop out. What no frame ever reveals is flagged in the holes matte, never invented -- turn on fill_holes to inpaint it and the matte still says where.

How to

How-to

Bake the shot's motion with a BS_VectorBake and name that bake in bake_path.
Wire the plate and a matte of the object to remove (matte_source chooses which input or channel).
radius is how many frames either side are searched; dilate grows the matte past the object's edge.
Read the holes matte: what no frame ever reveals is flagged there, and fill_holes inpaints it.

matte	the alpha that drives this node

Parameters

Parameter	Type	Default	What it does
bake_path	Text		The BS_VectorBake output this shot was baked to -- the fill travels through its vectors. Same knob as BS_VectorWarp.
radius	Float	12.0	How many frames either side to search for the revealed background. Wider finds more but costs more frames per render; if the object moves slowly you need more.
matte_source	Choice	auto	Which plane of the matte input is the object: its alpha, its luminance, or auto (alpha when it actually varies). `autoalphaluminance`
dilate	Float	2.0	Grow the object matte by this many pixels so its soft edge -- half background, half object -- is treated as object and never bleeds into the fill.
temporal	Float	0.5	How much nearer frames outweigh farther ones: 0 treats every frame alike, 1 halves the weight at the edge of the search. Raise it when lighting drifts across the shot.
conf_floor	Float	0.05	Below this vector confidence a candidate frame is not trusted for that pixel. Same meaning as on BS_VectorWarp.
fill_holes	Bool	false	Inpaint the pixels no frame ever revealed from their surroundings. Off, they stay the plate's own and the holes matte shows them; on, they are filled AND the holes matte still shows them, so the fill is auditable.
output	Choice	result	What rgba shows: the result, the holes matte (what nothing revealed), filled_from (which frame each pixel came from -- dark is early, bright is late), or the confidence. The same three ride along as layers cleanplate.holes / .from / .conf whatever is shown. `resultholesfilled_fromconfidence`
bake_budget_mb	Float	4096.0	Memory allowed for the loaded bake frames. If the search radius does not fit, the node says how many frames it dropped.
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
