A Flipbook image is a common technique of packing multiple frames into a single 2d image. In Houdini we use the Mosaic SOP node for that.
This node does the reverse, it takes a mosaic style image and breaks it back out into the original frames.
Parameters ¶
Rows
Number of frames expressed vertically
Columns
Numbers of frames expressed horizontally
Frame
Value of the current frame, usually $F
Start Frame
Value of the first frame in the sequence
