Rest

Rest here means bringing pixels to a line. The documentation places it in Image Pixel Tools and describes deformation of the image’s upper or lower part. The old text incorrectly promised restoration; this tool is not documented as damage detection, temporal analysis or denoising.

Channel selects Luminance, Red, Green, Blue or Alpha. This chooses data used to organize deformation, not five independent channel toggles. Inspect the selected Viewer channel: black-background luminance and opaque-background alpha describe different regions.

Floor Left and Floor Right are two points defining the reference line. Both have Y=0.5 in the source PNG, making the line horizontal. Different Y values tilt it. Do not collapse the points together or treat them as a 3D plane or collision system.

Position offers Up and Under for two placement modes relative to the line. Compare them on one marked silhouette and one line. Switching does not restore the upper or lower half of a frame from neighboring frames.

Amount controls influence. Separate reference states 0, 0.5 and 1 reveal which boundaries and details move. The brief BMD table does not specify pixel-selection equations, empty-channel handling or resampling rules; those cannot be inferred solely from the slider name.

The supplied images show Inspector rather than Flow. The teaching contract uses Input and Output for the required image path; it does not assert a standard Effect Mask on a particular wrapper. The local exercise uses a separate masked Merge and does not depend on an unconfirmed Rest port.

A moving source changes both channel data and deformation. Start with a held frame, then animate Amount, and only then inspect real footage. Temporal stability is something to review, not a promised stabilization feature.
